12-5010 is a type of General Purpose Plastic Film Capacitor made by GC Electronics. It is an electrolytic capacitor consisting of an anode, a dielectric, and a cathode in a plastic housing. This capacitor is a non-polarized, axial leaded, Ta/Polyester Film Capacitor that is rated to work at -30 to 85°C and at a voltage of 1-450VDC. It is designed for general use in commercial and industrial electronics. Its purpose is to act as a buffer, temporarily storing electrical energy and releasing it as needed. It is often used in circuits to reduce AC interference, smooth out pulses, timing circuits, and more.
