Introduction to Film Capacitors

Film capacitors are components which store energy in an electrostatic field. They are made from thin layers of plastic, such as polyethylene terephthalate (PET), polypropylene (PP), and polyvinylidene fluoride (PVDF). The layers have conductive metal coatings on the surfaces, which form the terminals of the device.

There are three main types of film capacitors; polypropylene (PP) capacitors, polyester (PET) capacitors and polyvinylidene fluoride (PVDF) capacitors. PP capacitors are widely used due to their excellent dielectric properties, while PET and PVDF capacitors have the advantage of greater temperature stability.

All film capacitors have excellent surge characteristics and are widely used in wide range of high-frequency applications, such as automotive and telecommunications.

B32521C3224K189

The B32521C3224K189 is a polyester film capacitor manufactured by EPCOS (now part of TDK). It is a non-polarized device, meaning that it does not have a positive or negative terminal and may be interconnected either way. The device has a rated voltage of 250V AC/DC and a capacitance of 2.2nF.

The B32521C3224K189 is a low-voltage, high-capacitance capacitor suitable for a variety of applications, including power supply filtering, frequency compensation, and cross-overs. Due to its robust construction, it is also suitable for high temperature and vibration applications.

Application Field and Working Principle

The B32521C3224K189 is designed for use in power electronic circuits and its main applications are power supply filtering, frequency compensation, and cross-over circuits. The capacitor\'s excellent characteristics, such as high capacitance and robust construction, make it well suited for use in harsh environments where high temperatures and vibrations are present.

The working principle of the B32521C3224K189 is the same as that of other film capacitors. It consists of two metal plates separated by a dielectric layer. The capacitor stores energy in an electrostatic field created by applying a voltage across the plates. This stored energy can then be used to filter power supplies, control frequency response, or create cross-over circuits.
