Film capacitors, also known as plastic film capacitors or plastic film dielectric capacitors, are capacitors which use a plastic film as the dielectric. Film capacitors generally have lower losses than other types of capacitors, and typically consist of a strip of plastic film insulated between two metal plates, one of which is often partially wound to form an electrode, with the two plates held together mechanically and electrically by a metal can. The ECW-H8363JL is a type of film capacitor designed for a variety of applications from audio electronics to power systems. This article will discuss the application field and working principle of the ECW-H8363JL.

The ECW-H8363JL is a non-polarized film capacitor that can operate in temperatures ranging from -55ºC to +85ºC, making it suitable for a wide range of applications in both extreme cold and hot temperatures. It is designed for high-reliability applications, such as power conditioning, EMI/RFI filtering, and DC blocking in medical and industrial electronics, and is also used in consumer electronics, automotive electronics, and aeronautical and aerospace applications. The ECW-H8363JL has a working voltage of 50V, a temperature range of -55ºC to +85ºC, an operating life of 15,000 hours, and a capacitance of 470μF. It also features a dielectric strength of 25 kV/mm and a low self-capacitance of 5.5 nF.

The ECW-H8363JL\'s construction is comprised of two metallized polypropylene films that are separated by an inter-leaf separator and encased in a flame-resistant epoxy resin. This structure provides dielectric insulation, low dielectric absorption, and stable capacitance over time and temperature variations. The dielectric film further adds to the reliability of the capacitor by providing maximum resistance against electrolytic corrosion, which is a common cause of component failure. Overall, the ECW-H8363JL is an optimal choice when long-term reliability and stable performance are desired.

In terms of working principle, the ECW-H8363JL operates in a similar way to a traditional capacitor, in that it stores energy through static electric fields. The metal plates of the ECW-H8363JL create two oppositely charged surfaces on either side of the dielectric film, which creates an electric field between them and stores energy. When a current is applied, the electric field creates an electrostatic force that moves charge carriers (electrons) from one plate to the other. As the plates charge, energy is stored in the capacitor, and when the current is removed, the energy is discharged and the plates reset to their original positions.

The ECW-H8363JL is a versatile, long-lasting film capacitor that is designed for a wide range of applications and is well-suited for both extreme cold and hot temperatures. It features a stable capacitance over time and temperature variations, and its dielectric film provides maximum resistance against electrolytic corrosion. The ECW-H8363JL operates in a similar way to a traditional capacitor, utilizing an electric field to store energy, and is a reliable choice when long-term stability and high-reliability performance is desired.
