In telecommunications equipment, it can be used in power supplies, input/output stages, and amplifier circuits. It is also commonly used in home appliances, professional audio equipment, instrumentation systems, and automotive electronics.

Working Principle of MAL214631471E3

Aluminum electrolytic capacitors are composed of two dielectric layers, separated by an electrolyte solution. The inner layer consists of an anode foil which is coated with a thin layer of oxide. The outer layer is a layer of aluminum foil which serves as the cathode. Between the two dielectric layers, there is an electrolyte solution which is composed of aluminum oxide, water, and a low concentration of acid. This electrolyte allows the capacitor to store and discharge energy.

When a voltage is applied, ions from the electrolyte migrate towards the cathode. This movement of ions creates a build-up of charge on the two electrodes which is called electrostatic double layer (EDL). This EDL acts as a smaller capacitor, partly shielding the two electrodes. This build-up of charge and the formation of an EDL is known as "activation" and is necessary for the capacitor to store energy.

When the applied voltage is removed, the ions within the electrolyte solution return to their original positions and the stored energy is discharged. This mechanism is known as "refrigerant".

The MAL214631471E3 capacitor is a radial aluminum electrolytic capacitor with screw terminals. It is rated for operation at a temperature range of -55°C to +105°C, and is designed to achieve a long service life in harsh operating conditions.
