Film Capacitors

Capacitors are widely used in electronic equipment and electrical circuits. Film capacitors, also known as plastic film capacitors, are capacitors with plastic film as dielectric. In the field of electronic technology, the application range of film capacitors is very wide, and now it has become the mainstream capacitor in the market. In order to meet the requirements of the development of electronic products in the electronics industry, 762M504912-162 Film Capacitors are developed and manufactured to provide reliable and stable performance for various application.

Application Field

762M504912-162 Film Capacitors have a wide range of applications, especially in power electronics. The main application fields include microelectronics, general-purpose inverters, UPS systems, frequency converters, and medical equipment. Applications such as power supplies, controller circuit boards, communication base stations, elevators, etc. It can be seen that 762M504912-162 Film Capacitors are widely used in various products and fields.

Working Principle

762M504912-162 Film Capacitors mainly use polyester film, Teflon film or polypropylene film as the dielectric material. The application of film capacitors can increase the frequency response range, reduce the resonance frequency, reduce the surge current and temperature rise, and eliminate high frequency interference. Due to the potential evenly distributed on the two electrodes, the dielectric loss is small, and the capacitors have small volume and large capacitance, and can be widely used in electronics, communications, and medical equipment.

The working principle of 762M504912-162 Film Capacitors is simple and clear. When a DC voltage is applied between two electrodes, a reverse electric field is formed between them. This electric field maintains the movement of charged particles, causing an opposite charge to build up on both sides of the dielectric. This charge separation represents a certain amount of capacitance, equal to one Farad when the voltage is one volt.

The capacitance of the 762M504912-162 Film Capacitor will decrease slightly with the increase of temperature, but the main influence on its performance is the dielectric loss. When AC is applied between the capacitor electrodes, the electric field keeps continually changing, which will cause the charge on the dielectric surface to leak out and the potential difference between the two electrodes decreases, resulting in dielectric loss represented by the constant of RMS.

Conclusion

In conclusion, 762M504912-162 Film Capacitors are widely used in power electronics, microelectronics, general-purpose inverters, UPS systems, frequency converters, medical equipment, etc. With the advantages of good insulation performance, small volume, large capacitance, low loss, and wide application, the 762M504912-162 Film Capacitors have become the indispensable electronic components in various products and networks.
