Aluminum electrolytic capacitors, abbreviated as AECs, are widely used electronic components, mainly the basic types of linear electric components. The ELXZ630ELL221MJ25S is an AEC represented by the part number code.

Application Field

The ELXZ630ELL221MJ25S is a compact radial leaded electrolytic capacitor. The capacitor is mainly for general automotive, light industrial, telecommunications and consumer electronics applications. It is a high ripple current version and suited for 125 Vac input applications. It has a series of features including long life (3000-6000 hours), high capacity, low impedance and high temperature resistance.

Working Principle

An aluminium electrolytic capacitor works in the same way as a conventional capacitor. It stores energy in the electric field between its two plates. However, unlike conventional capacitors, which use discrete insulated surfaces, aluminium electrolytic capacitors use an anode made of aluminium foil, which is etched to increase its surface area and create extremely small pores that trap the electrolyte. Since the pores are so small, they cannot be seen by the naked eye. When the capacitor is charged, ions from the electrolyte pass through the pores and attach themselves to the anode, creating an electrochemical reaction and forming a double layer of dielectric on the anode surface. This process allows it to store more charge than conventional capacitors and is what makes an aluminium electrolytic capacitor so efficient.

Package

ELXZ630ELL221MJ25S is offered in an axial leaded plastic package, and sealed to protect against dust and moisture. The physical size of the capacitor is 6x13mm.

Characteristics
