Film Capacitors

Film capacitors, also known as polyester capacitors, are a type of capacitor consisting of two pieces of metalized polyester film which are separated by a thin dielectric layer. Film capacitors are used in a variety of electronic applications due to their high capacitance and stability over temperature. Their certain thickness and dielectric materials provide advantages in capacitance, pulse handling capability, dielectric absorption, surge handling, and stability.

BFC237112823 application field and working principle

The BFC237112823 is a film capacitor manufactured by Beixin Electronics Co., LTD. It is used in a wide range of applications, including power electronics, motion control, switch mode power supplies, aerospace, defense, medical, and industrial applications. This capacitor is constructed using high performance polypropylene film as the dielectric material and aluminum foil as electrodes. This combination provides excellent frequency characteristics, humidity resistance, and long life.

The working principle of film capacitors is similar to that of a conventional capacitor. When a voltage is applied across the two leads, the electric field created by the voltage increases the electric field of the dielectric, resulting in an increase in capacitance. As the voltage across the capacitor increases, the stored charge increases. The stored charge corresponds to the capacitance value of the capacitor.

Film capacitors have several distinct advantages over other types of capacitors. Film capacitors are more stable than other types of capacitors since their capacitance is not influenced by frequency or temperature. This makes them suitable for high frequency, high temperature, or harsh environments applications. Film capacitors also have long shelf lives, low ESR, wide capacitance range, and low cost.

The BFC237112823 film capacitor from Beixin Electronics provides a wide capacitance range of 100uF to 1500uF. This capacitor provides excellent reliability, stability, and surge hoaning capability.
