GuangHuiy 50pcs CBB 474 100V 474k 0.47uF 470nF P10 Metallized Polypropylene Film Industrial Electrical s Two conductors that are close to each other, with a non-conductive insulating medium sandwiched in between, constitute a capacitor. When a voltage is applied between the two plates of a capacitor, the capacitor stores charge. The capacitance of a capacitor is numerically equal to the ratio of the charge on a conductive plate to the voltage between two plates. Capacitors play an important role in circuits such as tuning, bypassing, coupling, and filtering. It is used in the tuning circuit of Model GuangHuiy Brand Name AHBFC Unit Count 1.0 Count Item Weight 50 Grams Part Number GuangHuiy Manufacturer GuangHuiy
