Film Capacitors

A film capacitor is a type of capacitor that uses a thin plastic or paper film as its dielectric. This type of capacitor is widely used in a variety of applications, ranging from electrical power supplies to power conditioning equipment, and from audio and consumer electronics to heavy industrial process control. Film capacitors have a variety of shapes and sizes that are well suited for these applications.One particular type of film capacitor is the 38FB4430A-F. This film capacitor is designed to provide a high voltage tolerance and superior heat transfer performance, making it ideal for a variety of industrial applications. The 38FB4430A-Fis a three-terminal, metallised polyester quarter bridge, and is available in either radial or axial leaded versions. It is important to note that the38FB4430A-F is a non-polarised capacitor, meaning that it does not require polarity reversal for installation or use in electronic systems.

38FB4430A-F Application Field

The 38FB4430A-F is an ideal capacitor for a variety of industrial applications, including high frequency power switching applications, power sources, AC mains rectification and low-voltage DC power supplies. It is also suitable for a number of other applications, such as motor drives, inverters, UPS systems, welding systems, capacitor discharge applications and static switching circuits.It is particularly useful in high-temperature, high-coronary-temperature, and high-vibration applications, as it is able to withstand temperatures up to 125°C and peaks of up to 150°C. It is also RoHS compliant and has an operating temperature of -25°C to 125°C.

38FB4430A-F Working Principle

The 38FB4430A-F is a three-terminal, metallised polyester quarter bridge. Its operating principle is based on the fact that it is composed of a dielectric layer created by a combination of polyester plastic and metallised aluminium, which act as its two sections. The thickness of the dielectric determines the capacitance of the capacitor.When an AC signal is applied across the capacitor, the oppositely charged surfaces of the two sections create an electrical field that stores electrical energy. This electrical energy is then released when the signal is removed and the capacitor returns to its original state.The 38FB4430A-F is designed to provide high voltage tolerance and superior heat transfer performance due to the metallised aluminium section. This ensures that the capacitor can withstand high temperature applications and peak voltages of up to 150°C.

Conclusion

The 38FB4430A-F is an ideal capacitor for industrial applications that require high temperature, high-coronary temperature, and high-vibration environments. It is capable of handling peak voltages of up to 150°C and is RoHS compliant. Its non-polarised design means that it can be installed and used without requiring polarity reversal. Its three-terminal, metallised polyester quarter bridge design makes it ideal for a variety of applications, including high frequency power switching applications, power sources, AC mains rectification and low-voltage DC power supplies.
