Film Capacitors

A film capacitor, also known as a polyester capacitor, is a capacitor that uses a thin plastic film as the dielectric. This type of capacitor is widely used due to its stability, low price and large capacitance. It iss suitable in applications which require high accuracy and stability, like power supplies, timers or frequency control.

BFC237139184 application field and working principle

BFC237139184 is a film capacitor product with 380VAC rated voltage, 10/450/1350 voltage-sensitive characteristics. It is mainly used in AC and DC circuits of motor pool, motor, power tools and other small household electrical appliances, some complex circuits and high-performance filters. It has a small size, which is suitable for compact product design. Moreover, it is also mainly used in the adjustment of the DC operating voltage, rectifying connection, ripple absorption, filtering, voltage damping, starting capacitance, noise filtering, etc.. In addition, it also has a wide frequency range, high breakdown voltage and good temperature coefficient.

The working principle of the film capacitor is based on the dielectric electrostatic field developed by the insulation between the electrodes. The electric charges stored in the film capacitor are the result of the accumulation of positive and negative charges on opposite sides of the insulation. When a voltage is applied across the dielectric of a film capacitor, the positive and negative charges on the electrodes accumulate on the opposite sides of the dielectric layer, forming an electric field. The strength of this field increases with the increase of the applied voltage, which increases the storage of electric charges in the capacitor.

In conclusion, BFC237139184 is a multipurpose film capacitor product with the advantages of high frequency, high temperature and low loss. It has excellent performance and is suitable for motor pool, motor, power tools and other small household electrical appliances, complex circuit and high-performance filter, AC and DC circuits, etc. applications.
