Film Capacitors

Film capacitors are components which are made from multiple layers of electrodes which are covered by a thin film. Generally, the electrodes are of dielectric material and the material used for the film usually depends on the application and the acoustic properties needed. The materials used for the film can range from polypropylene, polyester, fluorinated ethylene propylene (FEP), polyetrafluoroethylene (PTFE), polysulfone, polycarbonate, and more.

In this article, we focus on the B32672L8472J189 film capacitor. The B32672L8472J189 film capacitor is a type of radial-leaded, non-solid-electrolyte aluminum electrolytic capacitor. This type of capacitor is commonly used for power factor correction, high-voltage applications, positive temperature coefficient (PTC) or negative temperature coefficient (NTC) thermistor applications, signal processing, and transient protection. Its key features include a long life span, long time stability, and high reliability.

The B32672L8472J189 film capacitor is composed of a single-cylinder body which is filled with a low-viscosity electrolytic fluid. The body is made of aluminum and serves as the anode. The anode is then covered in an insulating sleeve that serves as the film. The film is composed of a polymeric material and is sandwiched between two electroded films. These films are in turn attached to two Cathode seals.

The working principle of the B32672L8472J189 film capacitor is based on Faraday’s law of induction. This law states that a changing magnetic field induces an electromotive force in a circuit or any part of an electrical system. In the case of the B32672L8472J189 film capacitor, the changing magnetic field is generated by an alternating current (AC) power source. This AC power source causes the insulating polymeric film to become polarized and, as a result, an electrical current is induced in the capacitor.

The B32672L8472J189 film capacitor is an excellent choice for applications such as power factor correction, high-voltage applications, positive temperature coefficient (PTC) or negative temperature coefficient (NTC) thermistor applications, signal processing, and transient protection. Its long life span, long time stability, and high reliability make it an ideal choice for these applications. In addition, the fact that it is a non-solid-electrolyte capacitor means that it is also suitable for use in high-frequency applications and switching power supplies.
