Film Capacitors

Film capacitors are one of the many types of capacitors used in electrical circuits. The main function of a film capacitor is to store charge. They also act as a filter, smoothing out high frequency noise signals. Film capacitors are named for the dielectric material that is used as the insulator between the two metal plates. Film dielectrics are commonly made from polyester (PET), polypropylene (PP), or polycarbonate (PC). They are then wound in multiple layers to create a compact package. Film capacitors are preferred over other types of capacitors, such as electrolytic capacitors, because they have a low dissipation factor and a linear temperature coefficient.

BFC2373FB104MD application field and working principle

The BFC2373FB104MD is a type of film capacitor designed for power electronics applications. It is a pole type capacitor constructed with polyester dielectric. It is designed to provide high quality power energy storage and filtering. Its construction consists of a dielectric polyester film with Ag plating deposited on the aluminum anode and cathode electrodes. The capacitor operates over a broader temperature range than other types of capacitors, and is able to withstand higher frequencies. It offers low loss and high capacitance, and is very reliable.

The working principle of this capacitance unit is based on the capacitive effect of a capacitor. Capacitance is the ability of a device to store an electric charge and is measured in Farads. A typical BFC2373FB104MD capacitor has a capacitance of 0.1uF. When a voltage is applied across its terminals, a charge is stored on each of its plates. This creates a potential difference between the two plates. As current passes through the capacitor, the electric charge accumulates on each plate, creating an impedance that changes the shape of the input waveform.

The BFC2373FB104MD film capacitors are used in a wide range of power electronics applications and industrial control systems. They are commonly used in automotive, medical, and audio applications. Due to its superior performance, it is also used in high frequency switching converters. It is also suitable for applications that require low voltage drop or improved EMI filtering.
