It has an extended life due to its radial-leaded, non-polarized design, making it a reliable choice for many applications.

Working Principle

An aluminum electrolytic capacitor is a type of capacitor that has a larger capacitance than conventional electrolytic capacitors due to its use of aluminum surfaces as the anodes. The MAL215821272E3 operates on a simple principle: two thin aluminum plates are separated by an electrolyte. The electrolyte acts as an insulator to store electrical charge on the surface of the plates. When a voltage is applied to the plates, electrons are attracted from one plate to the other, creating an electric field. This electric field enables the capacitor to store and release energy as needed.

The MAL215821272E3 utilizes a non-polarized design and features capacitance ratings of 220μF, voltage ratings of 63V, and tolerance ratings of ±20% (40℃ / 100kHz). The capacitor also features an Intermittent Operating Temperature of +105℃. The capacitor can handle 1,000 hours of life at its rated temperature of +105℃ and can operate reliably over a wide range of -40℃ to +105℃ temperatures.
