Film capacitors, also known as film dielectric capacitors, polyester capacitors or plastic film capacitors, are electrical components which use a film as a dielectric. The ECW-FE2J105K film capacitor is a polyester-based type which is a long-life, low-profile, high-frequency, polyester film capacitor with an epoxy resin impregnation.

Application Field

ECW-FE2J105K film capacitors are widely used in various fields of electronics, such as:

• High frequency filters, low pass filters, notch filters, coupled filters and narrow-band filters
• Broadband communication systems, receivers and speakers
• Test and measurement instruments
• Power supplies, DC-DC converters and switching power supplies
• AC-DC converters and inverters
• Signal processors and audio equipment
• Control and measuring equipment

Working Principle

The ECW-FE2J105K film capacitors are based on a polyester film dielectric and an epoxy resin impregnation for moisture-proofing. The layered construction is designed to minimize changes to the capacitor due to temperature and humidity, thus ensuring a long life. The working principle is the same as other types of capacitors: the capacitor is able to store energy in the form of an electrical field between two conducting plates. The amount of energy stored depends on the amount of charge (Q) on each plate and the capacitance (C) of the capacitor.

Capacitance

The exact value of the capacitance of ECW-FE2J105K film capacitors depends on the thickness and type of film used, and the size of the area of overlap between the two conductive plates. As this overlap increases, the capacitance of the capacitor increases. The capacitance of ECW-FE2J105K film capacitors can range from 2.2nF to 4.7uF, however the larger value types are recommended for high frequency applications.

Dissipation Factor

The dissipation factor of ECW-FE2J105K film capacitors is very low, with a typical value of 0.002-0.008. This low value is due to the high dielectric constant of the film and the thin nature of the dielectric layer.

Leakage Current

The leakage current of ECW-FE2J105K film capacitors is very low, typically less than 0.001mA, which is suitable for applications requiring ultra-low leakage. This is due to the thinness of the dielectric layer and the epoxy resin impregnation, which minimizes the amount of ions which can pass through the dielectric.

Temperature and Humidity

ECW-FE2J105K film capacitors have an operating temperature range of -25°C to +85°C and an operating humidity range of 0% to 95%. This wide range of temperature and humidity makes them suitable for extreme operating conditions.
