Film Capacitors

Film capacitors are a type of capacitor that use electrically semi-conducting or non-conducting polymer materials as the dielectric medium. These capacitors have a higher temperature coefficient than ceramic or glass dielectric types and are the preferred choice for applications where high frequency, low ESR, and low impedance are needed. Due to the nature of the dielectric material, film capacitors offer a wide range of total capacitance and voltage ratings, with maximum working voltage ratings of up to 10KV.

ECW-HA3C222H4 application field and working principle

The ECW-HA3C222H4 is a film capacitor from the ECW series of capacitors manufactured by Solenoids Technology Inc. It is specifically designed for high-temperature, high-voltage applications. The ECW-HA3C222H4 features a Polypropylene film dielectric and a 100µF capacitance rating, with a maximum working voltage of 630V. It is rated for an operating temperature range of -40°C to +85°C. This capacitor is ideal for use in audio-frequency circuits, power supplies, DC/DC converters, and other high-voltage, high-temperature applications.

The ECW series of film capacitors use a special-type of dielectric film made of polypropylene with a non-polarized structure. When applied with an alternating voltage, this type of dielectric material exhibits a high degree of electrical insulation properties at high temperatures. The advantages of the ECW-HA3C222H4 are that it performs better than traditional capacitors with ceramic or mica dielectrics, as it is able to withstand temperatures up to 125°C, and it offers higher total capacitance at a lower working voltage. Additionally, it is designed for high-frequency applications, which makes it ideal for use in audio circuits.

The working principle behind the ECW-HA3C222H4 is the same as other capacitors – it uses two parallel plates, in this case consisting of the semiconductive or non-conductive polymer material, or dielectric, sandwiched between them. When a voltage is applied to the capacitor, electrostatic forces induce an electrical charge on the plates, storing energy in the dielectric material. When the capacitor is connected to a circuit, this energy is released in the form of electric current and the capacitor discharges.

The ECW-HA3C222H4 is a reliable and highly efficient capacitor perfect for high-temperature, high-voltage applications. With its wide temperature range, high capacitance rating, and high frequency performance, this film capacitor is an ideal choice for power supplies and DC/DC converters. It is also very cost-effective, making it a great value for any project involving high-temperature, high-voltage applications.
