PCIM Asia 2025, Asia's premier power electronics exhibition, will be held in Halls N4 and N5 of the Shanghai New International Expo Center from September 24th to 26th. Shanghai Yongming Electronics Co., Ltd. will exhibit its core capacitor solutions covering seven key sectors: AI servers, new energy vehicles, drones, robotics, photovoltaic energy storage, consumer electronics, and industrial control. Located at booth C56 in Hall N5, the exhibition will showcase its technological breakthroughs and domestic substitution achievements in high-reliability capacitors.

As a leading manufacturer of a wide range of capacitor products, including aluminum electrolytic capacitors, polymer capacitors, and supercapacitors, Yongming Electronics' comprehensive product line not only addresses application pain points across various industries but also demonstrates its technological strength by precisely benchmarking against leading international brands, demonstrating its commitment to "When faced with capacitor challenges, look no further than Yongming." The exhibition is expected to attract over 260 leading global companies, spanning 25,000 square meters, making it a vital window into technological trends in the power electronics industry.

AI Servers: Efficient and Stable, Powering the Computing Revolution

In the AI ​​server sector, Yongming Electronics exhibited three core products specifically addressing the stable operation needs of data centers. The IDC3, a bullhorn-shaped aluminum electrolytic capacitor, utilizes proprietary technology, boasts a withstand voltage of 450-500V and a capacitance of 820-2200μF. Designed specifically for high-power server power supplies, its high capacitance density and long lifespan eliminate dependence on imports. The MPD, a multilayer polymer solid capacitor, achieves precise filtering with an ESR (equivalent series resistance) as low as 3mΩ, rivaling similar Panasonic products in performance, providing ultimate voltage regulation for motherboards and power supply outputs.

For critical BBU backup power scenarios, the SLF/SLM lithium-ion supercapacitor module offers 3.8V/2200-3500F specifications, millisecond-level response time, and a cycle life of 1 million cycles, rivaling Japanese Musashi products in performance. These products, with their ultra-low ESR and high ripple tolerance, effectively reduce power supply ripple, ensuring stable 24/7 operation of AI servers and providing reliable energy support for cloud computing infrastructure. The exhibit covers core components such as AI server power supplies, motherboards, and storage.

New Energy Vehicles: Automotive-Quality, Driving a Green Future

Yongming Electronics' new energy vehicle capacitor series is fully AEC-Q200 certified—a stringent standard for automotive-grade passive components, requiring a product defect rate below 1 part per million (PPM), significantly higher than the 500 PPM standard for consumer-grade products. Exhibited products cover core components such as charging systems, electric drive and control systems, battery management systems, and thermal management systems, with the polymer hybrid aluminum electrolytic capacitors (VHE) performing exceptionally well.

The recommended VHE models, 25V 470μF/35V 330μF (10×10.5 size), offer stable operation for 4000 hours at 135°C, an ESR of only 9-11mΩ, and ripple current parameters superior to comparable Panasonic products, making them a drop-in replacement. In response to the trend toward 800V high-voltage platforms, metallized film capacitors (MDRs) offer a withstand voltage of 400-800VDC and a ripple tolerance of 350Arms. Their thermal stability at an operating temperature of 85°C meets the stringent requirements of main drive inverters, making them suitable for the current mainstream 400V/800V high-voltage automotive platforms. Liquid aluminum electrolytic capacitors (VMMs), with their high-temperature tolerance of 125°C and low ESR, provide high reliability for motor drive systems.

Drones and Robots: High Energy Density, Precise Control at Every Moment

Yongming Electronics exhibited two specialized capacitor products for the high-dynamic applications of drones and robots. The multilayer polymer solid aluminum electrolytic capacitors (MPD19/MPD28) offer a high withstand voltage of 16-40V and a capacitance range of 33-100μF, suitable for the electronic speed controllers of drones and model aircraft. Their extremely low ESR effectively suppresses current ripple and noise caused by power switching transistors, ensuring stable operation under extreme high-frequency and high-voltage conditions.

Conductive polymer tantalum electrolytic capacitors (TPD40) for robotic arm drives are available in large-capacity sizes, including 63V 33μF and 100V 12μF. Their ample voltage margin design allows for stable operation in key areas such as powertrains, flight control modules, and joint drives.

New Energy Photovoltaic Energy Storage: High Reliability, Protecting Energy Conversion

Photovoltaic energy storage exhibits focus on the long life requirements of harsh outdoor environments. Metallized film capacitors (MDPs) are suitable for PCS converters and offer a lifespan of up to 100,000 hours at 105°C, significantly exceeding that of traditional aluminum electrolytic capacitors. Their high capacitance density effectively stabilizes voltage and provides reactive power compensation, while their strong ripple resistance suppresses high-frequency noise and transient surges.

Cow-horn aluminum electrolytic capacitors (CW6), with a high voltage rating of 315-550V, are designed to withstand the transient high voltage and load fluctuations of photovoltaic systems. Their low ESR and high ripple resistance enhance system stability. Together, these two product categories provide high-temperature-resistant, long-life capacitor solutions for photovoltaic inverters, BMSs, and various energy storage systems, helping to improve energy conversion efficiency and system cycle life.

## Consumer Electronics and Industrial Controls: Compact, High-Efficiency, and Widely Compatible

The consumer electronics and industrial control exhibition area highlights the product advantages of "compact design + high performance." The liquid aluminum electrolytic capacitors (KCM) offer a lifespan of 3,000 hours at 105°C. The 400-420V/22-100μF specifications are smaller than the conventional KCX series, with significantly reduced diameter and height, making them suitable for the compact designs required by PD fast charging and smart home appliances.

The polymer solid aluminum electrolytic capacitors (VPX/NPM) feature an extremely low leakage current of ≤5μA, effectively suppressing self-discharge during standby mode. After reflow soldering, the capacitance stability of the 16-35V voltage range remains within twice the specified value. The smallest Φ3.55mm size offers 5%-10% higher capacitance than similar products on the market. For narrow and thin terminals, supercapacitors (SDS) and lithium-ion capacitors (SLX) offer specifications of 2.7-3.8V/1-5F, with a minimum diameter of just 4mm. Compared to traditional batteries, they offer faster charging speeds and longer cycle life, enabling the miniaturization of devices such as Bluetooth thermometers and electronic pens.

Conclusion

During PCIM Asia 2025, Yongming Electronics will host a product display and technical consultation area at booth C56 in Hall N5, where a team of engineers will be on hand to answer capacitor application questions. As a key player in the domestic substitution of passive components, Yongming Electronics showcased its comprehensive range of solutions, highlighting the technological breakthroughs achieved by Chinese companies in core power electronics components.
