Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors, are electric double layer capacitors with a dielectric made of aluminum oxide film. The largest characteristic of aluminum electrolytic capacitors is their large capacity. The specific capacity is related to its maximum operating temperature and working voltage. Its working voltage is usually between 16V and 450V.

The model B43305C9397M80 is an aluminum electrolytic capacitor. It is a high-temperature leaded type, which has a radial leaded design. The capacitance value of the capacitor is 470uF, and its operating temperature is up to 105℃. Its rated voltage is 25v, with maximum allowable ripple current of 8.32mv and life-span of 2000 hours at 105℃.

The most representative application field for model B43305C9397M80 is in industrial and audio frequency applications. The aluminum electrolytic capacitors are generally applied to power supplies, audio frequency processors, and light control instruments in industrial and audio frequency applications for mainly industrial equipment, communication devices UPS, LED drivers, audio amplifiers and many other instruments. The capacitors by this model have larger capacity in comparison of others and suitable for larger voltage power and equipment.

Working Principle

The principle of an aluminum electrolytic capacitor is that the aluminum anode is oxidized to an aluminum oxide film, and between the aluminum and the oxide film, there is a very thin insulation layer, into which an electrolyte is inserted, which stores an electric double layer effect. When the capacitor is subjected to excitation of voltage, the effect releases and generates a current. This electric double layer effect helps establish a charge and discharge effect in the capacitor.

In addition, the parameters of the aluminum electrolytic capacitor must be particularly considered, because too low a temperature or too large a ripple current will cause X and Y life on the single capacitor. Therefore, when selecting, the choice of the parameters related to the temperature and the ripple current should exceed the operating voltage. The voltage should be much higher than the working voltage, and the ripple current should meet the requirements of the load type.
