Film Capacitors

Capacitors are electrical components used to store electrical energy and regulate electrical current. Film capacitors use paper or plastic film as the dielectric to create electrical energy storage. For this reason they are often referred to as film dielectric capacitors, or simply film caps. One such model is the 940C30P15K-F, which has several applications and an interesting working principle.

940C30P15K-F Applications

The 940C30P15K-F is primarily a high voltage AC capacitor, with capacitor rating of 1500 volts and a capacitance of 30 microfarads. This makes it suitable for applications such as suppression of transient impulses in switching power supplies, AC line filtering, and power factor correction in power generators and motors. It can also be used to suppress radio frequency interference and harmonic generation in lighting systems, as well as for bulk power factor correction for power distributions. This particular film capacitor can also be used for low-level audio applications, such as active and passive high-end filtering designs. The 940C30P15K-F is mainly employed in industrial, medical, and high-level audio applications as well as elsewhere in special purpose applications.

Working Principle

The 940C30P15K-F is composed of a two or three-layer arch design with the film dielectric in the center, and two metal plates on the outside. The film is rolled which allows for a high voltage rating and a large capacitance. When a voltage is applied across the two metal plates, a charge will flow between them. The size of the charge depends on the capacitance, which is determined by the size and thickness of the dielectric film as well as its permittivity. The higher the permittivity, the higher the capacitance.The voltage will remain constant as long as the charge remains equal to its capacitance. As the current flowing through the capacitor increases, the capacitance decreases due to the decreasing amount of space between the metal plates. When the charge is different from the capacitance, the voltage will change accordingly.

Conclusion

The 940C30P15K-F film capacitor is primarily used for high voltage applications. It has a rating of 1500 volts and a capacitance of 30 microfarads. Its working principle is based on two or three-layer arch design with a film dielectric in the center and two metal plates on the outside. The capacitor works by storing charge on the film dielectric and releasing it when a voltage is applied across the two metal plates. It is suitable for applications such as RF suppression, power factor correction, bulk power factor correction, and low-level audio designs.
