Aluminum Electrolytic Capacitors

The MAL214250102E3 is an aluminum electrolytic capacitor, a type of capacitor that utilizes an electrolyte to create capacitance. This type of capacitor is distinguished from other types of capacitors by its wide range of capacitances, relatively large size, long shelf life and long operating temperature range.

This type of capacitor is constructed with a positive anode of aluminum foil, a cathode of aluminum oxide, and an electrolyte. An anodic film of aluminum oxide is formed on the surface of the positive anode. The formation of this oxide film increases the dielectric strength of the anode, and provides the capacitor with the necessary capacitance.

Application Fields

The MAL214250102E3 is used in many different industries and applications, including medical electronics, audio & video equipment, computing, telecommunications, LED lighting and automotive. It is highly reliable and has a non-inductive design, making it suitable for use with high frequency signals.

This type of capacitor is also highly suitable for use in consumer electronic circuits, such as laptops, cell phones and tablets. It is also commonly used in consumer grade AC/DC controllers, power supplies and adapters as well as in high & low voltage automotive applications.

Working Principle

The working principle for aluminum electrolytic capacitors is based on the dielectric strength of the oxide film that is formed on the anode. This oxide film acts as an interface between the aluminum foil and the electrolyte (an ionic conductor) to form a barrier resulting in a higher dielectric strength.

When a voltage is applied to the capacitor, the oxide film is weakened, creating what is known as a depletion zone. This zone reduces the capacitance of the capacitor, and increases the leakage current. As a result, the capacitance of an aluminum electrolytic capacitor decreases with applied voltage and increases when the voltage is removed.

The MAL214250102E3 has a high nominal capacitance of 1000uF, and a very low equivalent series resistance (ESR). This reduces the effects of the capacitance decrease, and increases the efficiency of the capacitor and its circuit.

Final Thoughts

The MAL214250102E3 aluminum electrolytic capacitor is a great solution for many different applications, including medical electronics, audio & video equipment, computing, telecommunications, LED lighting and automotive. It features a wide range of capacitances, low ESR, reliable operation over a wide temperature range, and a long shelf life. The working principle of an aluminum electrolytic capacitor is based on the dielectric strength of the oxide film that is formed on the anode and, when in use, the capacitance of the capacitor decreases with applied voltage.
