Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (also known as “electrolytic capacitors”) are polarised capacitors that are used in electronics where a large value of capacitance is needed in a relatively small volume. Many types of AC and DC applications use electrolytic capacitors due to their low cost, high efficiency, and easy to use. Due to the nature of the aluminum electrolytic capacitor design, they are very sensitive to temperature, voltage, and current, and require special handling in order to optimise their performance.

MAL210487102E3 Application Field and Working Principle

The MAL210487102E3 is a type of aluminum electrolytic capacitor specifically designed for DC application. It has a maximum DC voltage of 50 VDC, a maximum rated capacitance of 10,000µF, and surge voltage of 63.5 VDC. The MAL210487102E3 is designed for direct connection to the positive and negative power pins of the DC circuit, while the other two terminals of the capacitor are used for lead-in wiring. The MAL210487102E3 has a maximum Ripple current rating of 2.5A and a temperature rating of -20°C to +85°C.

In order to work, the MAL210487102E3 needs to be placed in a specific order, with the positive terminal connected to the positive power pin, and the negative terminal connected to the negative power pin. To maintain optimal performance, a small clearance and insulation is required around the MAL210487102E3 to avoid excessive heating due to resonance, and from current leakage from the circuit.

The working principle of the MAL210487102E3 is to store electric energy in its aluminum oxide double layer. This double layer is formed when the electrode material is in contact with the electrolyte solution, and is responsible for storing and releasing electric energy, and providing low impedance paths in the circuit. When the MAL210487102E3 is subjected to alternating or direct current, electrons are transferred onto the aluminum electrode which is then attracted by the anode to form the double layer.

The MAL210487102E3 aluminum electrolytic capacitor has numerous applications such as power supplies, LCD modules, protection circuit, and signal circuit applications. It is often used in combination with other components, such as diodes, resistors, and semiconductors, to form low and high pass filters which are used to control the frequency or signal power.
