Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as electrolytic capacitors, are a type of capacitors most widely used in electronic circuits. They use a semi-liquid electrolyte between two conductive metal plates which are connected to an anode and a cathode. They can be used to store charge, block low-frequency signals, filters, and also find use as pulse energy accumulators. One typical example of aluminum electrolytic capacitors is the MAL214099512E3.

MAL214099512E3 Application Field

The MAL214099512E3 is specifically designed for high voltage applications where a large capacitance is needed. It\'s a low-leakage and long life radial type capacitor with non-solid electrolyte. It can handle voltage from 25V to 100V and capacitance range from 100uF to 20000uF. Its excellent ripple current rating make it particularly popular for applications such as power supplies, switching mode power supplies, motor drives, various electronic apparatuses, and LCD display systems.

Working Principle

Like all capacitors, the aluminum electrolytic capacitor works on the principle of storing and releasing electric charge. In electrolytic capacitors, an electrolyte is used, which is a solution of an ionic compound, and it is the ionic compound that gives an electrolytic capacitor its unique properties. The two conductive metal plates housed inside the capacitor act as electrodes, and the electrolyte acts as a separator between them. All three of these materials come together to form the primary components of an aluminum electrolytic capacitor.

When a voltage is applied to an electrolytic capacitor, an electric field is created between the two metal plates. This electric field causes charge to flow from the positive terminal to the negative and causes a separation of charges between the two metal plates. These charges then form an invisible electrostatic barrier between the metal plates and prevent further current flow. That is, when a voltage is applied to the capacitor, it causes negative and positive charges to build up on corresponding plates, thus forming an electric field. The capacitor then acts as a storage space for this charge, freeing up the circuitry it’s connected to from having to send its own data right away.

Due to their large capacitance and excellent electrical properties, AL214099512E3 capacitors are ideal for high voltage, high power applications. This type of capacitor has very good performance in terms of temperature coefficient, capacitance stability, and noise filtering. Additionally, their low leakage current makes them suitable for a multitude of applications.
