High Voltage Film Capacitors in EV Charging and Renewable Energy Systems

26 Aug 2025

 

Kingtronics International Company — Inspired by Innovation

When engineers search for high voltage film capacitors, EV DC link capacitors, or renewable energy capacitors, they expect components with long-term stability, low dissipation factor, and reliable insulation resistance. As a professional manufacturer, Kingtronics provides the FKT-AC and FKT-AD axial polypropylene (PP) film capacitors, designed for EV charging stations, solar inverters, and industrial control systems.

Watch our factory in action — manufacturing capability & quality control for film capacitors.

Why Polypropylene (PP) Film Capacitors for EV & Renewable Systems?

  • High Voltage Range: suitable for DC link & inverter nodes in EV chargers and renewable systems.
  • Low Dissipation Factor: enables higher efficiency under switching frequencies.
  • Wide Operating Temperature: reliable performance in harsh environments.
  • Self-healing Property: enhances long-term stability and safety.
  • Flexible Options: axial construction (cylindrical / oval), broad capacitance selections.

Axial Film Capacitors — Series at a Glance (PP vs PET)

Series Dielectric Typical Applications Voltage / DF / Temp* Notes
FKT-AC / FKT-AD Polypropylene (PP) EV charging DC link, solar/wind inverters, industrial control High voltage capability; low dissipation factor; wide operating temperature. Engineer-centric; reliability-focused.
FKT-AA / FKT-AB Polyester (PET) Audio crossovers, DIY/consumer, household electronics Broad capacitance options; compact size; stable for signal/AC coupling in audio. Community-oriented; case-based content.

* For exact ratings (voltage range, dissipation factor by frequency, operating temperature, dimensions), please refer to each series datasheet on the product page.

Applications

  • EV Charging Stations — DC link & filtering in fast chargers (high voltage film capacitor / EV film capacitor).
  • Solar & Wind Inverters — renewable energy capacitor for long-term stability and efficiency.
  • Industrial Power Control — drives, UPS, automation (reliable axial film capacitors / DC link capacitors).

By partnering directly with a film capacitor manufacturer, you gain consistent quality, reliable lead times, and flexible supply for your EV, renewable, and industrial projects.

About

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval. Please visit our Products page, you could please download all our PDF datasheet and find cross reference for our Trimming Potentiometer and capacitors.
