As consumer electronics devices continue to evolve towards miniaturization and high power density, PCB layout space on smart digital power modules (power banks, PD fast charging adapters, USB-C docking stations, etc.) is becoming increasingly scarce, with limited board space. Traditional capacitors, constrained by materials and structure, have long faced a severe “capacity-volume” dilemma: increasing capacity requires more board space, while reducing volume often sacrifices filtering and energy storage performance. This directly restricts innovation and performance improvement in high power density designs of end products.
YMIN Solutions and Process Advantages
Shanghai YMIN Electronics Co., Ltd.’s YMIN VPX/VPT series of high-capacity-density polymer solid aluminum electrolytic capacitors, designed for smart digital applications, achieve higher capacity within the same package size. These high-capacity-density solid capacitors are specifically designed for smart digital power modules.
Compared to traditional liquid aluminum electrolytic capacitors, which are prone to capacitance decay, increased ESR, and increased leakage current under high-frequency, high-ripple, and high-temperature conditions, YMIN’s VPX/VPT series high-capacity-density polymer solid aluminum electrolytic capacitors utilize nanoscale high-voltage anode foil technology, special conductive polymer materials, and optimized electrode structure and dielectric layer density. This achieves higher capacitance within the same package (especially the 6.3×5.8mm small solid-state capacitor package) or significantly reduces size for the same capacitance.
Specific advantages include:
1. Approximately 10%–15% increase in capacitance compared to traditional solid-state capacitors within the same 6.3×5.8mm package;
2. Capacitor size can be reduced by up to approximately 25% for the same capacitance requirements;
3. Maintaining low ESR, high ripple resistance, and low leakage current performance under high-frequency, high-ripple conditions.
Application Scenarios and Recommended Models
YMIN VPX/VPT series solid-state capacitors are widely used in intelligent digital power modules, PD fast charging adapters, USB-C docking stations, power banks, and portable power supplies. They achieve higher power density and a simpler layout, fully meeting design goals and becoming the preferred solution for high-performance, high-reliability designs.
