Aluminum Electrolytic Capacitors

381EL331M160H022 application field and working principle

Aluminum electrolytic capacitors are widely used in various electronic products, mainly used to store energy. It is composed of liquid electrolyte, organic membrane, etc. Aluminum Electrolytic Capacitors model 381EL331M160H022 is an excellent performance multi-layer aluminum electrolytic capacitor, with highly reliable long life.

The application fields of 381EL331M160H022 are AI equipment, industrial robots, air conditioners, electronic appliances and other high-end electrical products. It has the characteristics of quick charge and release of energy and great energy storage capacity. It is also with high temperature stability, good temperature characteristics, stable performance, low leakage and high voltage resistance. Due to its high reliability, it is often used in critical applications requiring ultra-long life.

Working Principle

The working principle of 381EL331M160H022 aluminum electrolytic capacitor is similar to that of other electrolytic capacitors. It consists of two metal electrodes (anode and cathode) separated by an anion-permeable dielectric membrane. The anode is rolled up with the dielectric membrane into a cylindrical shape, and it is also impregnated with an electrolyte and sealed into a cylindrical aluminum shell. A ceramic capacitor is usually inserted into the center of the cylinder, providing a barrier capacitance. When voltage is applied to the capacitor, a voltage is generated on the dielectric membrane that allows anions to move to the other side of the membrane. These anions accumulate in layers, forming a double-layer capacitor with very low resistance and large capacitance.

This aluminum electrolytic capacitor has a unique feature, called the “self-recovery” effect. When the capacitor is overcharged and ruptured, the recovery of the broken membrane is completed within five minutes due to the restored charge balance. That is, the self-healing effect of the 381EL331M160H022 aluminum electrolytic capacitor makes the capacitor have a longer life than other electrolytic capacitors.

The 381EL331M160H022 aluminum electrolytic capacitor is widely used in many high-end electronic products, due to its excellent performance, reliability and long life. It can provide great convenience in various applications.
