Film capacitors, also known as plastic film capacitors, are one of the most widely used and versatile capacitor types. The F339MX231531JFP2B0 capacitor, manufactured by KEMET Electronics, is a general purpose film capacitor designed to improve performance in a wide range of applications. Its construction and operating principles allow for improved reliability and efficiency, making it a great choice for a wide range of applications.

Capacitor Construction

At its core, a film capacitor consists of an insulating dielectric (typically plastic), two metallic electrodes, and a pair of outer terminals for connecting an electrical circuit. The F339MX231531JFP2B0 capacitor is composed of a polycarbonate film dielectric, which provides excellent insulation and heat resistance. On each side of the dielectric is an aluminum electrode (one connected to the top terminal and one connected to the bottom terminal). Adding further reliability and durability, the entire assembly is hermetically sealed.

Working Principle

Like all capacitors, the F339MX231531JFP2B0 capacitor works by storing electric charge. When an alternating current (AC) is applied, the capacitor acts as an open circuit, allowing charge to pass through and be stored on one side of the capacitor while the other side remains neutral. When a direct current (DC) is applied, the capacitor acts as a closed circuit, blocking the flow of current.

The amount of charge the capacitor can store is determined by its capacitance, measured in Farads. In the case of the F339MX231531JFP2B0 capacitor, its capacitance is 1µF. This relatively low value is suitable for use as a bypass capacitor in AC circuits to smooth out voltage ripple, or as a filter capacitor in audio circuits.

Application Field

The F339MX231531JFP2B0 capacitor is one of the most versatile film capacitors available, making it suitable for a wide range of applications. For example, it can be used as an energy storage capacitor in a variety of power supply, lighting, and switching circuits to reduce noise and power supply ripple. It is also a great choice for use in automotive electrical systems, such as fuel pump relays and starter relays, due to its very low ESL and low leakage current. Additionally, it is well-suited to filter RC circuits used in oscillator circuits, switching regulator circuits, and digital/analog control circuits.

Conclusion

The F339MX231531JFP2B0 film capacitor from KEMET Electronics is a versatile part that can be used in a variety of power, lighting, and moving part applications. Its reliability and efficiency make it a great choice for designers who need a reliable and efficient capacitor. The excellent insulation of the polycarbonate dielectric, combined with low ESL and low leakage current, make it an ideal solution for both automotive and audio applications.
