Capacitors

Capacitors store and release electricity to maintain the circuit voltage at a constant level. Maintaining the circuit voltage also reduces circuit noise. Capacitors also insulate against direct current, thus eliminating noise and transmitting only the alternating current that acts as signal. They are found in most electrical circuits such as camera flush circuits and computer circuits and are an essential component in electronic devices. A capacitor consists of an insulator sandwiched between 2 electrical conductors. Capacitor performance varies depending on the insulator used and modifications. Available varieties include those with enhanced insulating and heat-resistant properties, high-precision products, products with high capacitance, etc., and should be selected according to operating environment and application.
