100% Brand new and high quality. 1uF~470uF = 12values *10pcs, total 120 pcs. Product Introduction: Electrolytic capacitor is a kind of capacitor. The metal foil is a positive electrode (aluminum or copper). The oxide film close to the positive electrode is a dielectric. The cathode consists of conductive materials, electrolyte (electrolyte can be liquid or solid) and other materials. Since electrolyte is the main part of the cathode, electrolytic capacitor gets its name. Mainly used in power filter, signal filter, signal coupling, resonance, DC isolation and other circuits.
