Film Capacitors

Film capacitors are electronic components with solid dielectric that are used to store electrical charge in a single electrical component. They are typically made up of two thin layers of metal, or conductive material, separated by a dielectric film, which can range from 5 micrometers to 500 micrometers thick. The dielectric film provides a medium between the two metal layers that allows electrical charge to be stored and released without any risk of short circuiting or power leakage.

The ECQ-E10102JFB film capacitor is a non-polarized capacitor that uses polypropylene as its dielectric material. The polypropylene is combined with an aluminum oxide film, which helps improve the resistance to temperature and the capacitor’s stability over time. The ECQ-E10102JFB has a capacitance range of 0.1 microfarad (μF) to 0.01 microfarad (μF) and an operating voltage range of 200 volts DC. It has a maximum leakage current of 2.5 microamps and a maximum temperature coefficient of 0.22%.

Applications

Film capacitors are a popular choice for applications that require low electrical losses and high reliability even when used in extreme environments. They are commonly used in high frequency circuits, audio applications, and in power supplies. The ECQ-E10102JFB film capacitor is commonly used in AC power lines, motors, DC-DC converters, low noise amplifiers, switching power supplies, as well as battery chargers and DC-AC inverters.

Working Principle

The ECQ-E10102JFB film capacitor works by storing an electric charge in its dielectric material which separates two thin layers of conductive material. When a voltage is applied to the two plates, an electric field is generated in between the plates, which stores the charge in the dielectric. When the voltage is removed, the stored electric charge is released back into the circuit. Film capacitors are characterized by their low electrical losses, since the dielectric material minimizes the leakage of electric current.

The ECQ-E10102JFB film capacitor has a voltage rating of 200V DC and a current rating of 2.5μA. Its maximum temperature coefficient of 0.22% gives the capacitor better temperature stability, ensuring reliable and consistent performance.
