B32653A2772J000

Film capacitors, also known as plastic film capacitors, polypropylene film capacitors, or film dielectric capacitors, are passive devices used in electronic circuits to store energy and to filter and smoothen signals. The B32653A2772J000 is a film capacitor that has many application fields and a specific working principle.

Application Field

The B32653A2772J000 is a non-polarized, snap-in MKT film capacitor. Its capacitance is between 0.0047 microfarads (uF) and 4.7 microfarads (uF), vibration resistant, and the temperature coefficient of the capacitance is +500 and -520 parts per million (PPM). With its quick installation feature, it is highly suited for use in transceiver equipment, and other devices that require many, compact components. With its high temperature coefficient and non-polar feature, it is the best choice for use in switched-mode power supplies, and other applications that require stability across temperature ranges.

Working Principle and Structure

The B32653A2772J000 consists of overlying plates (metallic layers) that are separated by a dielectric film in order to create the capacitance. The film is the dielectric, and it is usually a polypropylene film but it can also be other kinds of plastic films. This dielectric film provides electrical insulation between the plates, and it also provides a stability for capacitance through temperature variations. The plates, which are made from aluminum, are connected in parallel and they are connected to the leads of the capacitor. The dielectric film is placed between the two plates and the electric field created by the plate polarizes the dielectric film. The dielectric film stores electrical energy, which is used to charge and discharge accordingly, creating capacitance.

Conclusion

The B32653A2772J000 is a versatile film capacitor that has many applications and a specific working principle. It is non-polarized, easy to use, stable, and vibration resistant. It consists of separated plates (metallic layers) covered by a dielectric film, which provides the capacitance and the electrical insulation for the plates. This specific film capacitor is highly suited for use in transceiver equipment, switched-mode power supplies, and other devices that require many compact components.
