Film Capacitors

Capacitors are an integral component of any operation in the electrical and electronic industries. They store energy and help regulate current flow. Film capacitors are an important subset of capacitors developed to improve the performance of electrical systems. The 38FB4420A-Fis one of the most well-known film capacitors available today and is used in many applications and systems.

What are Film Capacitors?

Film capacitors are a type of capacitor made out of thin dielectric films such as polyester, polycarbonate and polypropylene. They are constructed by winding the film onto a spool and surrounded by metal electrodes. Film capacitors are often categorized according to their physical form, and can be found in axial (radial) and surface mount types. Film capacitors are generally more stable than electrolytic and ceramic capacitors, and offer superior performance in applications such as filters, power supplies and high-frequency circuits.

Advantages of Film Capacitors

Film capacitors offer a number of advantages over other types of capacitors. They are typically more reliable and less prone to leakage and breakdown. The dielectric films used in their construction provide excellent insulation, low parasitics and high current capability. Film capacitors also have superior temperature stability and are particularly well suited for high frequency applications. Furthermore, film capacitors do not suffer from moisture absorption, making them suitable for outdoor applications.
