Film Capacitors

Film capacitors are highly stable capacitors that use a thin plastic film (foil) as the dielectric material. The dielectric, often made from specialised plastics like polypropylene, polyester, or polystyrene, provides excellent electrical insulation. This thin film is sometimes metallised to enhance conductivity. A film capacitor is well-regarded for its robust reliability and excellent electrical properties, making it ideal for use in multiple electronic circuits. We provide a wide range of film capacitors with varied capacitance values, voltage ratings, tolerances, mounting configurations, and package options to meet your specific needs.

Why Buy Film Capacitors?

Film capacitors are an excellent choice for multiple electronic applications due to their robust reliability, stability, and impressive electrical performance. They are particularly valued for their low dielectric losses and high insulation resistance. Unlike other capacitors, film capacitors have a long operational lifespan and are less susceptible to aging effects, ensuring consistent performance over time.

Different Types of Film Capacitors Available: 

At Enrgtech, several types of film capacitors are available, each with specific characteristics and applications, including: 

  • Polypropylene (PP) Capacitors: A polypropylene capacitor is best known for high-voltage and high-frequency applications. These capacitors have low dielectric losses and excellent insulation resistance.
  • Polyester (PET) Capacitors: They provide a compact design and good stability for use in general-purpose applications.
  • Polystyrene (PS) Capacitors: PS capacitors exhibit high precision and excellent temperature stability. They are typically used in RF circuits.
  • Polycarbonate Capacitors: They are suitable for analogue signal applications due to good stability and low leakage current.
  • Metallised Film Capacitors: A metallised film capacitor features a self-healing property that makes it more robust and less prone to failure in high-stress situations.

Typical Applications of Film Capacitors:

Film capacitors find widespread uses in various electronic devices and systems, such as:

  • Power Supplies
  • Motor Run Applications
  • Industrial Electronics
  • Audio Equipment
  • Snubber Circuits
  • Automotive Electronics
  • Lighting Ballasts.
