As the electric vehicle (EV) industry moves toward higher-voltage architectures, the 800V platform has become a mainstream trend. This technological shift significantly increases charging power and shortens charging time, while also posing unprecedented challenges to core electronic components. Among these, the DC‑Link capacitor (DC‑support capacitor) – a critical energy‑storage component that connects the traction battery to the traction inverter, stabilizes the DC bus voltage, and absorbs high‑frequency ripple currents – has become a focal point for technology upgrades.
Foshan Pin'er Electronics Co., Ltd. has released a new‑generation DC‑Link capacitor solution. It features a metallized polypropylene film dielectric with an integrated copper terminal design, achieving a parasitic inductance of less than 10 nH and supporting 400 kW ultra‑fast charging systems. The product has already entered the supply chain of a leading domestic automaker and is scheduled for mass production in 2025.
Key technical highlights:
1. High energy density: Volume reduced by 25% compared to conventional products.
2. Long cycle life: Passed 2,000 fast‑charge cycles with capacitance degradation of less than 5%。
