Film Capacitors

film capacitors are non-polarized capacitors used for various applications, which are mainly distinguished by their dielectric construction. Film capacitors, sometimes also called plastic capacitors, are constructed with a thin film of plastic, polyester or polycarbonate material as insulation between two electrodes. The type of film capacitance used includes mainly polyester, polypropylene and tantalum film capacitors.

475MHBS70K2J application field

475MHBS70K2J capacitors are applied mainly in automotive, railroad and military applications. They are robust and have a wide temperature range, making them a suitable choice for a variety of power electronics applications. They are also suitable for use in RF applications, such as mobile radio and base station equipment.

Working principle

Film capacitors use dielectric films of plastic, polyester or polycarbonate material as the insulation between two electrodes. This enables them to store electric charge. When an electric current passes through the capacitor, charge is stored in the dielectric film. This charge creates an electrostatic field, which allows the capacitor to function. When charge is applied to the capacitor, it will store the charge until it is fully charged. When the capacitor is fully charged, it will begin to reduce its charge, until it is completely discharged.

Film capacitors are commonly used in power electronics for a variety of reasons. They are highly resistant to damage, operate at high voltages, and have excellent reliability, making them suitable for harsh environments. They are also non-polarized, meaning that they are not easily damaged by voltage spikes or surges. Furthermore, their dielectric construction allows for a wide range of capacitance values, allowing for high frequency operation. This makes them ideal for use in power supplies and DC/DC converters.

Conclusion

In summary, 475MHBS70K2J capacitors are ideal for a variety of applications due to their robust construction and wide temperature range. They offer excellent reliability, are highly resistant to damage, and can be used in a variety of RF applications. With their dielectric construction, they are able to store electric charge, allowing for a wide range of capacitance values at high frequencies. This makes them a suitable choice for power electronics applications.
