Film Capacitors

Film capacitors, or plastic film capacitors, are essential components in a variety of applications such as automotive, home appliances, industrial and energy control systems. As a result of their stability, film capacitors are very popular within the electronics industry where they are used especially in high temperature applications. Today, these capacitors are available in many types and varieties, each having a particular set of functions.

B32672Z5105K189 film capacitors are designed for a wide range of applications. Typical application fields include motor run, motor start, DC filtering, snubber, DC link, AC line bypass, and motor control circuits. The capacitor features a compact and robust aluminum case with high temperature and shock resistance, and a plastic or metal insert for better thermal performance. It also has a high stability and ripple current capability. In addition, the capacitor offers excellent protection against EMI/RFI.

Working Principle

B32672Z5105K189 film capacitors operate using the electrical charge transfer behavior of polarized film capacitors. Such capacitors consist of two metalized layers of polyester or polypropylene film that are separated by a dielectric layer. The metalized layers serve to connect the electrical leads of the capacitor, while the dielectric layers provide an insulating barrier between them. This barrier is the source of the capacitive platform, which provides the electrical insulation required in many applications.

The capacitor works on Faraday\'s Law of Electromagnetic Induction. This law states that when an electric field is applied between the two metalized layers, the resulting electrical charge is proportional to the field intensity as well as the dielectric material\'s relative permittivity. In a B32672Z5105K189 film capacitor, the two metalized layers and the dielectric material create a parallel-plate capacitor.

When an alternating current (AC) voltage is applied across the capacitor, the electric field between the two metalized layers creates a displacement current. This current moves through the dielectric layer and sets up the dielectric material\'s electric polarization in the opposite direction of the applied field. Thus, in the case of a B32672Z5105K189 film capacitor, the electric field creates an electric charge that accumulates on either metalized layer.

As the charge accumulates on either metalized layer, the capacitance fluxtuates with the applied voltage. This phenomenon is termed capacitance (or capacitive) response, and it’s used in applications such as high pass filtering to condition the audio signals. The B32672Z5105K189 film capacitor is also capable of producing a capacitive reactance that can create an inductive negative feedback loop.

Conclusion

B32672Z5105K189 film capacitors are designed for robust and reliable performance in applications such as motor run, motor start and DC filtering. These capacitors are powered by faraday\'s law of electromagnetic induction and use a combination of two metalized layers and a dielectric material to create a parallel-plate capacitor. As a result, the capacitors are capable of producing a capacitive reactance that creates a negative feedback loop. As such, these capacitors are extremely popular in the electronics industry, due to their high levels of stability and reliability.
