Film capacitors are a type of capacitor that uses an insulating film as the dielectric material. This type of capacitor is stable, reliable and highly resistant to mechanical and environmental stresses. The ECQ-E4394KFW is an example of a film capacitor and is designed to be a reliable and efficient power supply filter capacitor. It is also designed to withstand high temperature, has a long operating life and can be used for a wide variety of applications.

Application Field

The ECQ-E4394KFW is a highly effective power supply filter capacitor that is used to smooth out effects caused by fluctuations in a power supply. It is typically used in audio equipment, industrial power supplies, and medical equipment. Additionally, it is suitable for power line automation systems, basic industrial motors and other equipment requiring a highly reliable and efficient solution.

Working Principle

Film capacitors are composed of two conductive materials separated by a thin dielectric film. This film acts as an insulator, preventing the materials from making direct contact. When a voltage is applied across the two materials, the dielectric film stores electrical energy, blocking the flow of direct current and allowing the alternating current to pass. The dielectric film also blocks the flow of heat energy, contributing to the capacitor\'s high temperature and humidity resistance.

The ECQ-E4394KFW is a polypropylene capacitor, meaning the dielectric material is polypropylene film. This type of film is ideal for high-frequency applications, as it has low losses in comparison to other dielectric materials. The capacitor also has an electrolytic layer which helps to absorb any remaining heat. This improves the capacitor\'s efficiency and eliminates the need for heatsinks.

The ECQ-E4394KFW is a reliable and highly efficient power supply filter capacitor. Its polypropylene construction gives it high performance in terms of frequency response and temperature stability, while its electrolytic layer helps to improve its efficiency and temperature range. It is designed for use in a wide variety of applications and is ideal for use in audio equipment, industrial power supplies, and medical equipment.
