Introduction of Film Capacitors

Film capacitors are one of the main categories of passive components. A film capacitor is made of thin metal film with a dielectric between two electrodes and a terminal. It is usually used in AC circuits with low frequency. Film capacitors also exist as fixed-position capacitors and variable capacitors, their performance is good and their scope of application is very wide.

Features of ECQ-E2223JF3

ECQ-E2223JF3 is a film capacitor developed and produced by Chuangke Gaoke Electronics Co., Ltd, which is a dedicated capacitance components manufacturer. This product is a polyethylene naphthalate colophony film capacitor and its features includes, but is not limited to, low ESR, low self-inductance, large capacity, stable performance, reliable quality and so on.

Application Field of ECQ-E2223JF3

ECQ-E2223JF3 product is suitable for input filter, output filter, and frequency divider in televisions and audio products, power supplies of communication equipment and other consumer electronics, anti-interference filters and coupling capacitors of radio-frequency circuits and precision frequency measurement equipments, etc. They can be used in AC circuits with low frequency and wide temperature range. Besides, it also can be used for frequency selection for excitation circuit of motor and lamps.

Working Principle

Capacitance is a result of electrostatic condenser effects when an electric field is formed between two electrodes of paste films. Electric charge will produce a voltage difference between the electrodes, which will form a stationary electric field in the dielectric medium. During the process of charging, an electric charge will be drawn onto the film by an external force, and the same amount of opposite electric charge will be stored in the element’s terminal. Until the charge stored in the electrodes and terminals is balanced, a stable electric potential will be formed in the electric field and the capacitance internal electric potential is the same.

Conclusion

ECQ-E2223JF3 film capacitor is a great choice for AC circuits with low frequency. It has excellent performance, stable quality and wide range of application. Thanks to its good performance and reliable quality, it is widely used in a variety of electronic products.
