Introduction to Film Capacitors

Film capacitors are solid capacitors with thin semi-conductor film substrates and dielectric layers that provide outstanding electrical properties and reliability. They exhibit excellent temperature stability, high ripple current capability, low losses, long life and low ESR. Many types of film capacitors are available on the market for a variety of applications.

BFC237874823 Application Field and Working Principle

The BFC237874823 film capacitor is a high voltage polypropylene (PP) film capacitor designed for power supply, motor-start and lighting applications. The capacitor is characterized by low ESR and medium ESL values, and a high insulation resistance of up to 10,000 mega-ohms. Its rated voltage is up to 400V and its capacitance is from 1.2µF to 33000µF.The working principle of the BFC237874823 film capacitor is based on the effect of electrostatic charge. When an AC input voltage is applied to the capacitor, the alternating electric fields cause the electric charges on the two capacitor plates to move back and forth. This creates an electrical field between the two plates that stores and releases energy. The capacitor works like an energy reservoir, and it is able to store and release the electrical energy by the cyclic motion of the electric charges in the plates.When the power is turned off, the electric charge stored in the capacitor is also lost. This is why the life expectancy of a film capacitor is inversely proportional to its operating voltage. The higher the voltage of the capacitor, the shorter will be its life time.The BFC237874823 capacitor also features good self-healing properties, which protects the capacitor from heat and voltage stress. When the capacitor\'s insulation layer is damaged, the high electrical field causes the insulation to be repaired automatically. The heat generated during this process is also dissipated quickly.

Conclusion

The BFC237874823 film capacitor is a high voltage PP film capacitor developed for power applications. It exhibits good electrical properties, low ESR, high insulation resistance, and exceptional self-healing properties. It is able to store and release electrical energy while the power is applied, and it also features a long lifetime when compared to other types of capacitors. All these features make it ideal for a wide range of applications, such as power supply, motor-start and lighting applications.
