Film capacitors are used in many applications due to their high reliability, exceptional voltage range and temperature stability. Among them, BFC238640104 is one of the more commonly used film capacitors. The following is a brief introduction of its application field and working principle.

Application Field of BFC238640104

BFC238640104 is a metallized polyester film capacitor. It is widely used in printed circuit board applications such as power supply, voltage sensor, stroboscope, thyristor control circuit, battery-powered devices, high frequency DC-DC conversion, and motor control. It can also be used in electric welding machine, charge and discharge circuit in battery packs, electronic ballasts, automotive electronics, radio, television, audio and other lighting circuits.

Working Principle of BFC238640104

BFC238640104 is an alternating current capacitor. It is composed of two electrodes (metallized polyester film) and electrolyte dielectric. When AC power is applied, the electric field formed in the dielectric material between the two electrodes will allow current to flow in the form of alternating current. The electric charge (capacitance) stored in the capacitor will cause the current to decrease and finally reach a balanced state.

The capacitance of the BFC238640104 mainly comes from its construction. Its two metallized polyester film electrodes are separaed by a dielectric material. The capacitance is determined by the size of the two electrodes and the distance between them. The higher the capacitance, the greater the electric charge stored in the capacitor.

In addition to its inherent capacitance, the insulation resistance of the BFC238640104 is also of great significance. Its insulation resistance mainly comes from the two insulating substrates. In order to ensure it works effectively, it must ensure that the two insulating film electrodes and the dielectric between them can not be broken down at high voltage.

Conclusion

BFC238640104 is a film capacitor with high reliability, temperature stability, exceptional voltage range and long-term stability. It can be widely used in printed circuit board applications. Its capacitance is determined by the size of the two electrodes and the distance between them. Its insulation resistance mainly comes from the two insulating substrates. With its good performance, it is an ideal choice for many power applications.
