Aluminum electrolytic capacitors are one of the most commonly used and versatile capacitors available in the market. They are made of an anode, a cathode and a dielectric, which are all composed of an aluminum oxide film. This oxymethylene paper film, which is located between the two electrodes, is porous and acts as an insulator. The anode or the positive terminal is made of aluminum foil that has been covered with a thin anodic oxide film. The anode has a cylindrical shape and, at the side, holes are made in order to create electrical contact with the electrolyte. The cathode, which is the negative terminal, is made of aluminum covered with a thin layer of cathodic oxide film. It also has a cylindrical shape with a number of holes to create contact with the electrolyte.

The 860130874006 aluminum electrolytic capacitor is an example of these devices, having a jacking-in type construction. It has a capacitance of 33µF, rated voltage of 500Vdc, and a ripple current of over 1A at 105°C. Its maximum operating temperature is 105°C, so it can sustain elevated temperatures without malfunctioning. Its applications range from general purposes like power supplies, decoupling, and bypassing, to complex ones like converter, inverter, or switching regulator. The 860130874006 capacitor also works on audio-video equipment, car audio, and mechatronics, especially under high temperature or high voltage conditions.

Aluminum electrolytic capacitors exhibit several advantages over their paper-wound counterparts. They offer high capacitance values, good thermal stability, long life, and good performance in high temperature applications. Moreover, they can reach a smaller size and are often used when it is not possible to use other types of capacitors due to space reasons. They reach excellent insulation and stability, being environmental friendly and eliminating the risks of fire.

The operating principle of aluminum electrolytic capacitors is relatively simple. The applied voltage charges the anode creating a positive pressure that pushes away the dielectric layers of the capacitor, creating a conduction path between the terminals. In the absence of a voltage they stop conducting, thus blocking current flow. The applied voltage is actually creating a charge in the electrolytic medium and the current that is produced is seen as movement of ions. The behavior of the electrolytic capacitor is unlike other voltage-controlled components such as ceramic capacitors or semiconductor devices, which behave linearly to voltage, or other magnetic components, which behave linearly to an applied frequency.

In conclusion, the 860130874006 aluminum electrolytic capacitor is an excellent choice for high temperature and high voltage applications. It has a jacking-in type construction, a capacitance of 33µF, rated voltage of 500Vdc and ripple current of 1A. It provides good thermal stability, long life and excellent insulation, as it works in accordance with the operating principle of aluminum electrolytic capacitors. Suitable for both general and complex applications, it is highly recommended for power supplies, car audio, and mechatronics.
