Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, also known simply as an electrolytic capacitor, is a polarized capacitor which utilizes an electrolyte to achieve a larger capacitance per unit volume than other capacitor types. Aluminum-electrolytic capacitors can have capacitance values in the range of µF to many thousands of µF. The most popular type of aluminum electrolytic capacitor is the radial leaded type. These have one lead exiting the can along the negative terminal, and the insulation sleeve along the positive terminal.

MAL212875159E3 application field and working principle

MAL212875159E3 aluminum electrolytic capacitors are typically used in DC power supplies, power supplies for LED lighting, DC/DC converter circuits, battery chargers, high frequency inverters, and audio amplifiers.

The working principle for these capacitors is that they provide a reactive component between the two plates of the capacitor. The capacitance of the device is inversely proportional to the distance between the two plates, so by increasing the distance between them, a higher capacitance value can be achieved. The electrolyte acts as a dielectric medium between the plates, providing a high value of capacitance while allowing for current flow between the plates.

In addition, the design of the MAL212875159E3 capacitor allows for a higher rated voltage than other aluminum electrolytic capacitors. An aluminum electrolytic capacitor is able to withstand higher DC voltages than other types of capacitors due to the high breakdown voltage of the electrolyte. This makes them ideally suited for applications operating at higher voltages.

The MAL212875159E3 capacitor also provides a lower ESR than other aluminum electrolytic capacitors, making them suitable for applications which require a high ripple current. By utilizing aluminum as the dielectric material, the ESR can be kept low, reducing the chance of overheating and providing a higher reliability.

In conclusion, the MAL212875159E3 aluminum electrolytic capacitor is a highly reliable and robust device, and is well-suited for applications that require a high capacitance, low ESR, and high voltage rating.
