Aluminum Electrolytic Capacitors refer to capacitors with an anode of aluminum foil covered with an oxide film; cathode of liquid or solid electrolyte. The advantage of this kind of capacitor is that its volume can be made very large with small size. Therefore, it is often used in occasion where big capacity but small size is necessary. And among Aluminum Electrolytic Capacitors, the EKXJ161ELL221ML25S is one of the most common one.

EKXJ161ELL221ML25S is an axial lead, electrical and mechanical compliant, 220μF, 25V aluminum electrolytic capacitor. It is a miniature surface-mount device which is designed to provide very low profile with improved electrical and mechanical properties. It can provide long life and high reliability, and it has very good temperature characteristics.

As a one of the most common capacitor among Aluminum Electrolytic Capacitors, the application field of the EKXJ161ELL221ML25S is quite wide. Starting with general purpose electronics, like portable receivers, power amplifiers, computer host systems, etc. Then to medicine field, like medical imaging systems. It can also be used in a wide variety of consumer electronics, such as air conditioner, washing machines, refrigerator, etc. It can also be used in electronic toys and even in some heavy duty application, like aerospace or military, such as radio communications or navigation control.

The working principle of the EKXJ161ELL221ML25S is quite simple. The anode of the capacitor is made of aluminum foil printed with tin, which covered with an oxide film. The foil is immersed in an electrolyte and electrically connected with the cathode by means of a bridge-like conductive area or a liquid or solid electrolyte. A voltage difference between the anode and the cathode, electrostatic attraction of particles occurs, causing the dielectric of the capacitor become condensed, thus forming An electric field between the anode and the cathode. Since electricity is not conducted for the dielectric, the capacitor can store electric energy.

In conclusion, the EKXJ161ELL221ML25S is a medium sized and medium voltage aluminum electrolytic capacitor. It has great reliability and long life which makes it welcomed by a wide variety of application field and occasions. And its working principle is quite simple.
