Film capacitors are high-precision, high-performance components used to store electrical energy. They are often used in automotive, medical, power supply, electrical engineering, telecommunication, and consumer electronics applications. The ECW-H20202HV is an example of a film capacitor. This component is made up of two thin metalized plastic films that act as dielectric electrodes held together by a dielectric medium or film. The two electrodes are connected together with welding and resistive connections to form the electrical circuit. The value of the capacitor is determined by the thickness of the film used.

The ECW-H20202HV capacitor is designed for high-frequency applications, such as radio and television sets, cellular phones, and automobile audio systems. It has a high operating frequency of up to 500 kHz and an equivalent series resistance (ESR) of 0.85Ω. Furthermore, it is a total RoHS compliant component and its metalized plastic film is UL-94 approved for use. It can operate at temperatures between -40 °C and 85 °C and it has a low dielectric absorption. The component is constructed with flame retardant materials, so it is safe to use in high-power applications.

The working principle of a film capacitor is relatively simple. When a voltage is applied to the terminals of the capacitor, it creates an electric field within the dielectric, which causes the random movement of atoms. These atoms interact with the electric field in such a way that they all move in the same direction. As a result, an electrical displacement (measured in Coulombs) occurs, which further creates an electric field in the opposite direction of the applied voltage. This creates an electrostatic attraction between the plates of the capacitor that maintains an electric charge on the plates.

The ECW-H20202HV film capacitor has a high dielectric strength, making it suitable for applications that require high-reliability components. Its metalized high-temperature PET film is durable and resistant to oven aging. Additionally, its construction is moisture and vibration resistant. The component is also resistant to capacitance and inductance change, making it ideal for communication, electronic power, and automotive applications.

Overall, the ECW-H20202HV is a highly reliable and precise film capacitor designed for a variety of applications. It can be used in radio and television sets, cellular phones, and automobile audio systems to store electrical energy. Its construction ensures it is highly resistant to capacitance and inductance change and its dielectric strength is high. This makes it suitable for high-reliability applications.
