YuhChang MPP Capacitor Manufacturer – High Performance MPP Film Capacitors for Industrial Applications
As a leading MPP capacitor manufacturer, Yuhchang specializes in the design and production of high-quality MPP film capacitors for use in energy storage, filtering, and pulse applications. Our MPP type capacitors are trusted by customers worldwide for their exceptional performance, long lifespan, and reliability in demanding environments. In addition to MPP film capacitors, we also offer a wide range of other power electronic capacitors to meet diverse application requirements.

What Is an MPP Capacitor?
An MPP capacitor, or Metallized Polypropylene Film Capacitor, is a type of film capacitor that uses a self-healing polypropylene dielectric material. Known for their low loss factor, high insulation resistance, and stable electrical characteristics, MPP capacitors are ideal for high-frequency and high-voltage applications. Unlike aluminum electrolytic capacitors, MPP capacitors offer superior thermal stability and longer service life, making them the preferred choice in modern power electronic systems.

Applications of MPP Capacitors
Yuhchang MPP film capacitors are engineered for diverse industrial applications that demand reliability and efficiency. Common applications include:

  • DC link and DC filtering in industrial power converters and traction systems
  • Low power drives requiring consistent voltage and current performance
  • Impulse discharge applications such as magnetizing and welding systems
  • Ideal for replacing aluminum electrolytic capacitors when lower capacitance and higher pulse current handling are required  

Whether for renewable energy systems, electric vehicle components, or automation equipment, our MPP type capacitors provide unmatched durability and electrical performance.
