Film Capacitors

A film capacitor, sometimes referred to as a plastic capacitor, is a capacitor primarily intended for AC signal applications. It is one of the formative capacitors, which are predominately used to store and transport energy with particular values of parameters that are needed for various different environments. Film capacitors offer good voltage and temperature stability, low dielectric absorption, and low leakage current over a wide range of frequencies. Due to its high performance and long life, a film capacitor is an ideal choice for many pulsed circuits.

BFC247018105 is a particular type of film capacitor, more precisely a polypropylene capacitor. It has a maximum voltage rating of 63V AC and a capacitance of 0.018μF. It is equipped with a reliable metalized polypropylene film or cardboard construction and can handle high levels of temperature. Thanks to these characteristics, BFC247018105 is suitable and widely used in many applications such as switching power supplies, medical equipment, high-voltage applications, inverters, electrical motors, and so on.

BFC247018105 Application Field and Working Principle

Application Field

BFC247018105 is suitable for a variety of switching power supplies, medical equipments, inverters, electrical motor and so on. It requires reliable insulation and other special characteristic during operation. Internally, it consists of an insulating film. On one side of it, thin metal layers are added as electrodes. Dielectric constant is equal to 2.2 while dissipation factor is less than 0.1%. Nonlinearity of the capacitance is less than 5%

Working Principle

Film capacitors BFC247018105 are AC-only capacitors. They are used to store electrical energy at a variety of frequencies. Being insulated by a thin metal film, the negative and positive electrodes them can store energy for alternating current when an AC voltage is applied to them. Because of the thin metalized layers, it could dissipate the heat rapidly during operation.

The capacitance of BFC247018105 varies with the AC frequency, temperature and voltage. It shows a strong non-linearity and has a high dissipation factor at higher frequencies. It is also suitable for AC signal applications, because film capacitors usually have low dielectric absorption, good voltage and temperature stability as well as a low leakage current over a wide range of frequencies.
