Film Capacitors

Film capacitors, also commonly referred to as plastic film capacitors, are electrical components designed to store and discharge electrical energy and have the capability to convert electrical energy into mechanical energy. Film capacitors are typically constructed from two conductive surfaces and a dielectric material. The two conductors may be either two separate pieces of metal foil or a combination of a metalized film with a tab connected to the foil. Each type of film capacitor has its own unique characteristics, including voltage, temperature, and frequency ratings.

ECW-FE2J155J Application Field and Working Principle

The ECW-FE2J155J is a film capacitor specifically designed for motor applications. It has a high-temperature rating of 150°C, making it suitable for use in motors, generators and other high temperature applications. The ECW-FE2J155J features a high dielectric strength of 10,000 VDC, low inductance, and low equivalent series resistance. This makes it highly suitable for use in high-current, high-frequency applications. Additionally, the ECW-FE2J155J has a UL 1414 listing and is RoHS compliant.

The ECW-FE2J155J film capacitor works by creating an electric field between the two electrically connected electrodes and the dielectric material in the capacitor. The dielectric material is an insulating material with a dielectric constant (K) which decides the amount of electric energy stored in the capacitor for a given voltage. This principle is known as the capacitance effect and when an alternating current flows through the capacitors, the capacitors are forced to store alternate amounts of energy. The magnitude of the electric charge stored in the capacitor is determined by the capacitance and voltage of the capacitor.

The ECW-FE2J155J film capacitor also features a small equivalent series resistance (ESR) of less than 0.5 Ohms, making it ideal for smooth, low-ripple operation. The low inductance also makes it highly suitable for use in high-frequency applications. Additionally, the ECW-FE2J155J has a long life span, withstanding up to 500,000 cycles. This allows for long-term reliable operation in many different applications.

Conclusion

The ECW-FE2J155J is an exceptionally versatile film capacitor due to its ability to withstand high temperatures, high-current, high-frequency applications and its long lifespan. This makes it suitable for a variety of motor applications. Additionally, its high dielectric strength and low ESR make it highly reliable in many applications. Together, these features make the ECW-FE2J155J an excellent choice for film capacitors.
