• Introduction to Film Capacitors
  A film capacitor is an electrical component which is similar to a traditional cylindrical capacitor in terms of function but has a flat plate design. The plates are sandwiched between layers of plastic (polyester, mylar, polypropylene, etc.) with aluminum contacts which allow electricity to flow through them. Typically, these capacitors are used in high frequency applications and are designed to provide a high level of stability and performance.
  Film capacitors provide a range of attributes that make them ideal for specific applications in the electronics industry. These capacitors feature a high degree of stability over temperature, voltage, and humidity. They are also able to withstand excessive levels of current, making them perfect for transient suppression applications. Some types of film capacitors also offer small size and low cost, which make them suitable for a wide range of applications.
