Film Capacitors: ECW-FD2J395KQ Application Field and Working Principle

Film capacitors, also known as polyester capacitors, plastic film capacitors or very generally as paper and oil capacitors, are capacitor construction types in which two electrodes are separated by a dielectric plastic film. They are classified as a type of dry capacitor. The modern film capacitor industry began with the development of polyethylene terephthalate (PET) in the 1940s and continued to evolve with the advent of polypropylene (PP) and polytetrafluoroethylene (PTFE) in the 1970s. ECW-FD2J395KQ is a product of film capacitors. It is a film capacitor with a capacitance of 0.0039 μF, a working voltage of 50V or 100V, and a tolerance of ±10%. The special feature of this product is its low lead length and high ripple current capabilities. In this section, we will discuss its application field and working principle in detail.

Working Principle of ECW-FD2J395KQ

The working principle of ECW-FD2J395KQ is based on the principle of capacitance. When two conductive and polarized plates are separated by an insulating dielectric such as a film, a capacitor is formed. This capacitor stores an electrical charge and is able to provide energy even when the input voltage changes. The most common dielectric materials used in film capacitors are plastic films such as polyethylene terephthalate (PET), polypropylene (PP), and polytetrafluoroethylene (PTFE). These dielectrics are chosen due to their superior characteristics such as high breakdown voltage, very low losses, and low temperature coefficient of capacitance. ECW-FD2J395KQ’s thin and flexible polypropylene film allows for a high ripple current capability. This allows it to be used in high frequency applications, such as in power conditioning, where accurate resolving of ripple currents is essential. Overall, the ECW-FD2J395KQ is a versatile film capacitor that can be used in many different applications. Its small size and high ripple current capability make it an ideal choice for industrial automation and power conditioning applications. Additionally, its wide temperature range makes it a suitable choice for automotive audio systems and instrumentation circuits.
