Introduction

Film capacitors usually refer to the capacitors with plastic films and they are widely used in various kinds of electronic equipment. Among them, ECQ-E10683KF is a kind of miniature metallized polyester film capacitors which is produced with advanced techniques. The film capacitors can have features of low dissipation factor, high insulation resistance, good self-healing property and long life span etc.

Application Field

ECQ-E10683KF is of low voltage, so it is mainly used in household appliances and other kinds of electronic equipment such as TV sets, audio devices, air conditioners and other electric motors. Because ECQ-E10683KF has good electrical performance, stable frequency response of power amplifiers, excellent durability and stable temperature coefficient, it is especially excellent for audio-frequency filtering, oscillation loading and wave-trapping in intermediate frequency circulation system of radio receivers. ECQ-E10683KF is also applicable in time delay circuit, energy storage system, bypass circuit and DC-blocking applications.

Working Principle

The basic working principle of ECQ-E10683KF is that when an AC voltage is applied, a capacitive current flows through the capacitor. The capacitive current is proportional to the applied AC voltage. The electric field generated by the AC supply will polarize the film and charges of corresponding polarity will be accumulated on both sides of the electrode and dielectric. As a consequence, the capacitance of ECQ-E10683KF is mainly affected by thickness and distribution of the film and the directivity of the eddy currents induced in the external electrical circuits. Under DC supply, it may form an electrical double layer on the surface of both sides of the dielectric which produces the DC and AC voltage that may discharge the capacitance.

Conclusion

ECQ-E10683KF is a kind of miniature metallized polyester film capacitor which has features of low dissipation factor, high insulation resistance, good self-healing property and long life span etc. It is mainly used in household appliances and other kinds of electronic equipment such as TV sets, audio devices, air conditioners and other electric motors. Its working principle is that when an AC voltage is applied, a capacitive current flows through the capacitor and the directivity of the eddy currents induced in the external electrical circuits will affect the capacitance.
