Advantage

 












Vertical integration capability





Independent control of core processes such as thin film coating, slitting and winding to reduce supply chain risks.







Strict quality control





IATF 16949 automotive grade certification, full inspection of voltage resistance, ESR, and life span for each batch of products.







Rapid mass production capability





Flexible production line supports small customized orders and large-scale deliveries.









 







Application Scenario

 






 




  • On-Board Chargers (OBC) (input/output filtering)

  • Motor Drivers (IGBT Buffer Capacitors)

  • Battery Management System (BMS) (voltage sampling decoupling)

  • DC/DC converter (high voltage isolation capacitors)

  • Electric drive systems (EMC filtering to suppress radiation)



 







FAQ

 






 







Q: How is the rated voltage selected?





A: It needs to be higher than 1.5 times the maximum operating voltage of the circuit and consider temperature derating.







Q: What are the capacity error ranges?





A: Commonly ±5% (J), ±10% (K), ±20% (M), some precision capacitors up to ±1%.







Q: What is the operating temperature range of film capacitors?





A: -40°C to +105°C (conventional), special models can support -55°C to +125°C.
