It can be used in motor controllers, signal amplifiers, TV receivers, audio amplifiers, frequency reducers, electroplating circuits, communication systems, household appliances, and various other power electronic circuit designs. It is also used in many high frequency, high power, and high voltage circuits.

Working Principle

SCD474K202A3Z25-F film capacitor works on the principle of electric charges that are stored and released through an electric field. When a voltage is applied to the capacitor, electric charges are stored on the plates of the capacitor. The electric charges are released when the voltage is removed from the capacitor. This process is repeated when the voltage is cyclically applied and removed from the capacitor, resulting in an alternating current. The rate of charge and discharge depends on the capacitance of the capacitor. The higher the capacitance, the more charges it can store and release.

SCD474K202A3Z25-F film capacitor consists of a plastic film sandwiched between two metal plates. The plastic film works as a dielectric material which resists the flow of electric charges and stores the charges when a potential difference is applied across its terminals. The plates are connected to the outer world by leads or terminals which are soldered on them. The leads are used to connect the capacitor to other electrical components in the circuit.
