In the wave of miniaturization and high-density iteration in electronic devices, the limited space in PCB (Printed Circuit Board) layouts and the performance limitations of traditional capacitors have become common challenges in the industry. Shanghai Yongming Capacitors' ultra-thin packaged solid-state capacitors, thanks to groundbreaking technology, achieve a dual breakthrough of "smaller size and better performance," successfully solving this dilemma. They have already been applied in products such as wireless chargers and desktop charging docks, providing a new solution for the upgrade of electronic devices worldwide.

Technological Innovation: Ultra-thin Design + Core Performance Breakthrough

Traditional electrolytic capacitors, due to their bulky size, high ESR (Equivalent Series Resistance), and short lifespan, are difficult to adapt to high-density design scenarios such as multi-layer boards and high current applications. Yongming has achieved a significant reduction in package thickness while maintaining the same capacitance value by innovatively adopting high-conductivity polymer materials and optimized winding processes.

Its flagship VP4 series boasts a world-leading thinnest capacitor at a mere 3.95mm surface mount height, covering a rated voltage range of 6.3V to 35V. At a capacitance of 220μF, its ESR is only 60mΩ, balancing low loss and stability. The other core series, VPX, features a compact 6.3×4.5mm size, reducing volume by 22% and height by 1.3mm compared to traditional capacitors, improving space utilization by nearly 30% and freeing up crucial space for internal expansion or the addition of new functional modules.

All products in the series have passed high-temperature life tests at 105℃/2000H or 125℃/2000H, with some VHT series products achieving an even longer durability of 125℃/4000H, reaching industry-leading levels of reliability.

Scenario Application: Two Typical Applications Validate Practical Value

Wireless Charging: Single Capacitor Replaces Multiple MLCC Clusters

In wireless charging product design, traditional solutions require an array of 10-20 MLCCs (Multilayer Ceramic Chip Capacitors) to meet capacity requirements. However, this approach suffers from issues such as effective capacity decay with voltage and temperature, large space requirements, susceptibility to cracking, and potential for howling noise.

Yongming's VPX series 25V 100μF solid-state capacitor (6.3×4.5mm) can directly replace this array. It not only maintains over 95% of its capacity and stably provides 100μF of effective capacity, but also compresses the component's space to a single point, eliminating noise issues caused by piezoelectric effects. This reduces design complexity and overall cost, significantly improving production yield.

Desktop Dock: Enabling High-Density, Multifunctional Integration

The Anker 14-in-1 Display & Charging Dock, a representative product of multi-interface, high-density design, features four Yongming VPX series solid-state capacitors (two 25V 220μF and two 25V 100μF). Leveraging its ultra-thin packaging, the device achieves multi-interface integration and high-performance power supply while maintaining a compact design.

The freed-up space not only optimizes internal wiring and heat dissipation but also provides redundancy for future functional upgrades, demonstrating Yongming capacitors' core value in "freeing up design space and enhancing performance options" in high-density electronic devices.

Market Landscape: The Rise of Domestic Capacitors Breaks International Monopoly

For a long time, the global high-end capacitor market has been dominated by Japanese and Korean brands. Yongming, through its continuous deep cultivation in high-frequency, high-capacitance, and ultra-thin technologies, and with technological leadership and product reliability as its core competitiveness, has gradually replaced Japanese and Korean brands, becoming a core capacitor supplier for global power supply design.

Currently, its products are widely used in various electronic devices such as power banks, wireless chargers, and desktop docking stations, providing global manufacturers with capacitor solutions that are "smaller, more stable, and more durable." In the future, Yongming will continue to focus on technological innovation, driving the development of solid-state capacitors towards thinner and higher performance, helping electronic devices achieve a perfect balance between "high performance and extremely small size."
