Film capacitors are components that store electrical energy in the form of electrical charges. They are made up of two electrically conductive electrodes, separated by a dielectric material and have very low impedance and very low leakage current. The most common type of film capacitor is the metallized polyester film capacitor, commonly referred to as a polyester capacitor. The BFC238323104 is a type of metallized polyester film capacitor and is used in a wide variety of applications which include snubbers, DC-link capacitors, and AC-motor run capacitors.

Application Field:

The BFC238323104 is suitable for a variety of applications due to its high operating temperature capabilities, low ESR, low equivalent series resistance (ESR), and withstanding of high voltage. As well as the quality of film, this capacitors is specifically designed to work in a circuitry requiring the voltage to remain constant, this type of capacitor can is used in DC link capacitors where it can provide reliable constant power even on inhomogeneous voltage environments. It can be also used as snubbers, pulse motor and power applications.

Working Principle:

The working principle of a film capacitor relies on the fact that electrical charge will be stored on the dielectric material, which is the nonconductive material sandwiched between the two conductors. The magnitude of the stored charge is determined by the capacitance, which is simply stated as the ratio of electrical charge to voltage. When the capacitor is charged, a voltage is applied across it from one side to the other. This causes the electrons of the metal plates to be attracted to one another, leaving behind a net positive charge on one plate and a net negative charge on the other. The capacitance is then determined by the amount of electrical charge stored on the plates and the applied voltage.

When voltage is then applied to the plate, an electric field is created, which causes electrons to be pushed away from the negative end of the capacitor, through the dielectric material and onto the positive end. The more electrons that are pushed onto the plates, the greater the capacitance of the device. This effect is what is used in the BFC238323104 to store electricity.

The main advantages of using this type of capacitor over other types are that it has an extremely low equivalent series resistance (ESR), which is important for the applications it is used in. It also has a high operating temperature range, up to 200°C, which makes it suitable for many high temperature applications. It also has a very low leakage current, which could potentially disrupt the electrical and production system.
