Film capacitors are divided into organic dielectric thin-film capacitors, metalized film capacitors, and polyethylene naphthalate capacitors. The ECQ-B1822JF series is a major application field of metalized film capacitors. Here we discuss its application field and working principle.

Application Field of the ECQ-B1822JF Series
The ECQ-B1822JF series is a polyester metalized film capacitor. It has the advantages of low loss, low parasistance, low dielectric absorption, and high ripple current capability. It can be used in a wide range of applications, such as high frequency and high voltage switched-mode power supplies, AC/DC and DC/DC switching converters, PF correction circuits, line output filters, high-precision operation amplifiers, HF/VHF radio receivers and transmitters, high frequency switched mode power supplies, pulse circuits, diode bridge circuits, and LED lighting circuits.

Working Principle of the ECQ-B1822JF Series
The ECQ-B1822JF series is a polyester metalized film capacitor. It works by storing electrical energy in the form of electrostatic field using metallic films as electrodes. The electrodes may be either metallized aluminum foil or metal plates. During capacitor operation, an electric current flows through the electrodes and generates a capacitance field between them. The electrons in the capacitance field create an electric field that stores the electric energy. The capacitance of the capacitor is determined by the surface area of the electrodes, as well as the dielectric material used to create the electric field.

The ECQ-B1822JF capacitor has a wide range of applications due to its low losses, low parasistance, low dielectric absorption and high ripple current capability. Its construction and layout, as well as its operating voltage and temperature, need to be carefully considered. Its suitability for use is largely dependent on the application and environment in which it is used.
