The ECW-H12202RHV capacitors are a type of film capacitor that includes many features, which makes them the ideal choice for a wide range of applications.

The ECW-H12202RHV film capacitor is a general-purpose product developed for automotive and industrial applications. It is made from metallized polyester film with a brass end-plate. It has a dielectric strength of 4000 V, an insulation resistance of 6000MΩ, and a capacitance range of 0.001µF to 0.1µF. The product is also RoHS compliant, so it satisfies all the requirements of the Directive 91/338/EEC on the restriction of hazardous substances. The capacitors are rated for an operating temperature range of -25℃ to +85℃.

Working Principle

The working principle behind the ECW-H12202RHV capacitor is based on the basic principle of capacitance. Capacitance is the ability of a device to store an electric charge. A capacitor consists of two conductive plates separated by an insulating material known as a dielectric. When a voltage is applied to the plates, electrons move and create an electric field. The capacitance of the device is determined by the size and separation of the plates, and the dielectric material used. When the applied voltage is removed, the charge remains stored on the plates.

Application Field

The ECW-H12202RHV film capacitors are suitable for a wide range of applications, such as motor starting, motor run, flash lamps, filters, signal conditioning, power supplies, and voltage regulation. In automotive applications, they can be used in spark plug and fuel injection systems, interior lighting, alarms, and other similar applications. In industrial controls, they can be used in contactors, circuit breakers, relays, and motor control circuits. In switchmode power supplies, they can be used for smoothing high voltage and surge requirements as well as filtering to reduce ripple.

The advantages of the ECW-H12202RHV film capacitors are their long life, high reliability, low cost, and small size. They are capable of withstanding harsh environmental conditions and are a suitable solution for many different applications. The ECW-H12202RHV is a quality product that offers reliable performance with very little maintenance.
