Film capacitor is also called plastic film capacitor. It takes plastic film as dielectric.

Structure of Plastic film capacitors:

The internal structure of the film capacitor is mainly composed of metal foil (or foil obtained by metallization on plastic) as electrode plate and plastic as dielectric. It is produced by winding or laminating process. Different arrangements of foil and film lead to a variety of structure.

Classification of Plastic film capacitors:

Thin film capacitor is composed of dielectric, electrode, electrode transition, lead out, package, seal and mark.
According to the media classification: polyester film, polypropylene film.
According to the structure classification: winding type, laminated type, inside string type.
According to the electrode classification: metal foil, metallization (aluminum metallization, aluminum zinc metallization), film foil composite structure.
According to the electrode lead out way classification: radial, axial.
According to the packaging mode: box type, immersion type, bare package.

Plastic film capacitors Summary

Thin film capacitor is the closest "ideal capacitor", but it has the advantages of high voltage, high power, high frequency, high stability, high reliability and long service life. It is used in automobile, locomotive, wind power, photovoltaic and other equipment to replace electrolysis.

WEET 3.3uF +/-5% 250VDC MKP Precise Audio Capacitor is the best choice for audio crossover application and speaker system.
