(hereinafter referred to as "Nantong Xunye") has officially rolled out its CD294 series 450V/1000µF 35×70mm S4 snap-in aluminum electrolytic capacitor. This product provides inverter manufacturers with a domestic, localized solution that seamlessly balances high performance with cost efficiency. Targeting Inverter Pain Points with Dedicated Solutions In industrial inverters, ripple currents and voltage spikes generated by the high-frequency switching of IGBT modules have consistently posed critical challenges to equipment stability and lifespan. Nantong Xunye’s CD294 series is engineered specifically to optimize performance under these demanding operating conditions. Featuring a compact 35×70mm footprint and a 4-pin (S4) design, the capacitor significantly enhances mounting stability on PCBs without increasing costs or compromising assembly efficiency, making it a perfect fit for mainstream inverter models. Leading Core Performance Indicators with Distinct Competitive Advantages According to the technical director of Nantong Xunye, the CD294 series outperforms comparable market alternatives across several key performance metrics: Higher Ripple Current Capability: It can withstand a ripple current of up to 4.2A (100Hz) at 105°C, whereas standard products from average market manufacturers typically offer only around 2.5A. This superior capability allows the capacitor to more effectively smooth DC-bus voltage and absorb peak interference, delivering a more stable and clean power environment for IGBT modules. Extended Operational Lifespan: The capacitor features a rated life of 2,000 hours at 105°C, with internal testing validating a reach of up to 3,000 hours. Under an 85°C operating environment, the actual service life can reach 8,000 to 10,000 hours, perfectly matching the long-cycle, continuous operation reliability requirements of industrial equipment. Low ESR Design: The Equivalent Series Resistance (ESR) is kept as low as 100mΩ (100Hz), which markedly reduces internal power dissipation and temperature rise. This enhances overall system energy efficiency and alleviates thermal design pressure. Furthermore, by optimizing the electrolyte formulation, excellent high-temperature characteristics are maintained despite the low ESR.

Medium-Power Inverters (11kW - 30kW): 4 to 6 units connected in parallel. High-Power Inverters (Above 37kW): Screw-terminal type capacitors are recommended. Component Selection Guidelines The technical team at Nantong Xunye offers the following selection advice for engineering designs: Voltage Margin: The rated voltage should be 1.2 to 1.5 times higher than the actual operating voltage. The 450V specification is suitable for a 2-unit series configuration on a 380V-class inverter bus voltage (approx. 540V). Lifespan Estimation: The actual operating life of a capacitor is heavily influenced by the operating temperature. It is highly recommended to position the capacitors within the cooling airflow channel, keeping the ambient temperature below 85°C. Ripple Current Verification: Designers must ensure that the actual ripple current in the circuit does not exceed the rated value; otherwise, overheating will lead to a sharp decline in component lifespan.

The latest "Global Quarterly Handheld Smart Camera Market Tracking Report, Q4 2025" released by International Data Corporation (IDC) shows that the global handheld smart camera market will ship 16.65 million units in 2025, a year-on-year increase of 83%. The sales revenue exceeded 46.1 billion yuan, a year-on-year increase of 86%. IDC predicts that by 2030, the global handheld smart camera market is expected to exceed 40 million units, with a five-year compound growth rate of nearly 20%.   From a macro perspective, although there are differences in the development of economies around the world, global per capita GDP and disposable income of residents continue to rise in the long run. The terminals of smart device users have rapidly extended from traditional tools such as PCs, mobile phones, and tablets to diverse AIoT devices, and new scenarios and ecosystems continue to emerge and iterate, reshaping the industry landscape.   In recent years, both in China and globally, short video, Vlogs, and social media traffic have shown a clear explosive trend. With the creation, storage, and sharing of a massive amount of exponentially rich and diverse content, the demand for intelligent devices for terminal shooting among active users worldwide has entered a new niche and redefined. Traditional digital, DSLR, and mirrorless cameras are already in a downward trend, with a more mature user base that leans towards photography enthusiasts. More demands are focused on high image quality, optical lens combinations, professional photography, native image quality, and relatively complex and extensive post-processing. They are non portable and have a relatively high average price.   IDC's definition of handheld smart cameras refers to consumer grade portable imaging devices that have computing processing capabilities, are equipped with electronic or optical image stabilization capabilities, have a resolution of 2K or higher, and can be handheld, including motion cameras, panoramic cameras, and pan tilt cameras. Among them, motion cameras are further divided into detachable motion cameras (commonly referred to as "thumb cameras" in the market) and non detachable motion cameras.   From the perspective of major competitors in the global handheld smart camera market in 2025, DJI ranks first with a 62% market share in shipments. In the fields of panoramic cameras and "thumb cameras" (defined by IDC as detachable motion cameras), DJI has continuously released competitive new products and achieved rapid growth, accelerating global expansion and becoming the main driving force for DJI's significant leadership in the global market. Yingshi maintains a leading position in the global panoramic camera and "thumb camera" (defined by IDC as a detachable sports camera) market, with the release of the Go Ultra new detachable sports camera and the Ace series innovative gameplay kit achieving crowd segmentation. Under the pressure of DJI and Yingshi, GoPro has been significantly impacted in both panoramic and motion camera fields, with a noticeable contraction in shipments.   Sports camera market: By 2025, the global shipment of sports cameras will exceed 8 million units, a year-on-year increase of 61%. DJI and Yingshi have both achieved good performance with their popular flagship products, and their market share in terms of shipment volume has significantly increased. The veteran manufacturer GoPro is facing strong competitive pressure. Among them, the detachable motion camera, also known as the "thumb camera," will have a shipment volume of over 1.3 million units in 2025, with a significant growth rate. Yingshi has a first mover advantage and leading position among them; In the second half of the year, DJI's new product 0smo nano made a strong entry into the market with its performance advantage and achieved impressive performance.   The market for pan tilt zoom cameras: In 2025, the global shipment volume of pan tilt zoom cameras increased by over 100% year-on-year, and DJI has a significant leading advantage in this market. The handheld gimbal camera accurately locates short video Vlog shooting scenes and has been widely praised and sought after by a group of users. Pocket has become synonymous with this market and has also attracted attention from manufacturers in different circles. In 2026, this market may usher in a new round of players and competition.   Panoramic camera market: By 2025, the global shipment volume will exceed 2.5 million units, with a year-on-year growth of over 50%. Yingshi has been developing and maintaining a leading position in the field of panoramic cameras for many years. DJI launches Osmo 360 new product in the second half of the year, entering the panoramic market with a significant increase in market share throughout the year.   Looking back at the global handheld smart camera market in 2025 and anticipating future market development, the following characteristics are expected: 1. The market size and penetration rate still have ample room for growth. Compared with the huge market sales of mature intelligent terminal devices, the handheld smart camera market still has great development space regardless of market size and user penetration rate. With the continuous improvement of product user experience and the gradual decrease of unit price, IDC predicts that by 2030, the global market size of handheld smart cameras is expected to exceed 40 million units, with a five-year compound growth rate of nearly 20%.   2. The supply chain is facing challenges and short-term pressure on performance growth. The price of memory has skyrocketed and there is no hope of recovery in the short term. The average price of handheld smart cameras is less than 2800 RMB, and compared to other smart devices, the higher proportion of memory costs may have a greater impact. The core manufacturers have already stocked up in large quantities, and the larger the volume, the stronger the upstream bargaining power and the more resilient the supply chain. They can partially absorb the cost pressure, but at the same time, they face fierce market competition, and their profit margins are squeezed, resulting in pressure on their performance in 2026.   3. Camera manufacturers' image quality output software algorithms are gradually emerging, and intelligent editing is becoming increasingly important for consumers. Camera stabilization, depth of field blurring HDR、 Night scenes, noise reduction, and other image quality performance, as well as post production video editing, all rely on body algorithms, manufacturer apps, or third-party software to achieve. Although traditional cameras and mobile phones already have mature algorithms and massive data, due to differences in shooting scenes, motion cameras and panoramic cameras still need to accumulate a large amount of user data to promote deep adaptation of algorithms and hardware, and optimize imaging effects. With the rapid expansion of the handheld smart camera market and the surge in user base, the algorithmic advantages of top manufacturers continue to amplify and have become core competitiveness.          

According to Omdia's latest research, in the fourth quarter of 2025, the Indian PC market (excluding tablets) will grow by 17% year-on-year, with shipments reaching 4 million units, mainly driven by strong demand for laptops. The shipment volume of laptops reached 3.2 million units, a year-on-year increase of 22%, benefiting from holiday demand, strong online promotions, and year-end inventory push from retail and e-commerce channels. Thanks to stable procurement by enterprises and institutions, desktop computer shipments increased by 2%, reaching 87 10000 units. Due to consumer demand and promotions offsetting the impact of weak education deployment, the tablet market also achieved moderate growth in this quarter, with shipments reaching 1.1 million units, a year-on-year increase of 3%. The strong performance in the fourth quarter of 2025 has led to a total of 15.9 million units shipped in the Indian PC market for the year, a year-on-year increase of 12.5%, setting a historical high in annual shipments. Among them, laptop shipments drove most of the growth, reaching 12.3 million units, a year-on-year increase of 15.2%; Desktop computer shipments increased by 4%, reaching 3.6 million units. Mainly due to delays in government led education projects, the tablet market decreased by 18% year-on-year, with shipments reaching 4.9 million units. However, if education demand is excluded, the tablet market grew by 12.8% year-on-year, demonstrating strong consumer demand.Omdia senior analyst Ashweej Aithal said, "As supply side pressures and rising component costs begin to affect device affordability, the market outlook for 2026 remains cautious. The impact of rising storage chip prices is particularly significant, but processor and GPU costs are also expected to rise, which will limit PC shipments to 14.3 million units, a year-on-year decrease of 9.8%, and the market returns to normal levels after record shipments. Driven by the delayed implementation of the education procurement project, the tablet market is expected to grow by 2.1% to reach 5 million units. ”         Omdia senior analyst Ashweej Aithal added, "The rise in component prices may reshape the purchasing behavior of various segmented markets, and buyers will be more cautious when upgrading equipment. This impact will be most evident in mainstream consumer and entry-level commercial PCs, as the price sensitivity of these segmented markets remains high. Manufacturers may absorb some of the cost increases through promotions, but sustained cost pressures may still suppress demand in price sensitive markets. ”        The shipment volume of PC education market in India has decreased by 5%, reflecting delays in institutional procurement projects. However, the ELCOT contract to be executed from the end of 2025 may provide early impetus for the deployment of the education market in 2026. Overall, the commercial PC market in India is expected to decline by 8% in 2026, but with the implementation of new education tenders, the education market is expected to grow by 14%. Aithal pointed out that education procurement remains an important influencing factor in the Indian PC market, and the upcoming bidding will shape the market trend in 2026. ”        The shipment volume of tablets in India decreased by 18% to 4.9 million units. The commercial tablet sector fell 52%, mainly due to government led delays in education bidding. The demand for small and medium-sized enterprises and enterprise tablets has also declined, as procurement slows down and institutions adopt cautious spending strategies. In contrast, the consumer end grew by 21%, benefiting from strong demand both online and offline, strong promotional efforts from manufacturers, and holiday promotions.         Aithal said, "Although rising component costs may suppress entry-level demand, this could accelerate the already evident trend towards high-end in the Indian PC and tablet markets. As the prices of entry-level devices rise, the price gap between mainstream and high-end systems narrows, prompting buyers to upgrade to devices with stronger performance and longer lifespan
