Film Capacitors

Film capacitors, often known as plastic film capacitors, or simply a film capacitor, is a capacitor that applies a film as its dielectric, hence the name film capacitor. Typically, the films used are polyester (Mylar), polypropylene (PP), polycarbonate (Lexan), polyphenylene sulfide (PPS), or Teflon, although applications exist for other polymers. Film capacitors may have a range of capacitance values, depending upon the dielectric and thickness chosen.

The BFC241617504 film capacitor is an axial-lead capacitor with a metallized polypropylene dielectric. This type of capacitor has a number of features which make it very popular in a range of electronic applications. It has high insulation resistance, excellent stability, low leakage current, low losses, and low noise generation. The excellent dielectric characteristics of this type of capacitor make them suitable for use in high frequency AC circuits. As well as this, they also offer advantages when used in DC circuits, such as high peak inverse voltage capability and very low ESR. This type of capacitor can also be used for a variety of low power applications, including filtering, decoupling, and bypassing.

The operating principle of the BFC241617504 film capacitor is based on the basic principle of capacitance. When a capacitor is suitably charged, an electric field is established between the plates of the capacitor. This electric field causes electrons to be attracted toward the opposite plate and in doing so, it builds up an electric field between the plates of the capacitor. This electric field is what is referred to as electrical capacitance.

The capacitance of a film capacitor is affected by several factors, which include the type of dielectric used, the size of the capacitor, and the ambient temperature. Generally speaking, the higher the capacitance value, the larger the size of the capacitor. Furthermore, the capacitance of a film capacitor changes with the ambient temperature. As the temperature increases, the capacitance decreases.

The BFC241617504 film capacitor offers the possibility of medium to low voltage applications with rated voltages up to 4KV. Depending on the application, various lengths and diameters can be used to give a wide range of capacitance values. The capacitance of this type of capacitor can range from 0.001μF to 4.7μF.
