Aluminum electrolytic capacitors are a type of capacitor that offers high capacitance in a very small package. The internal construction of this type of capacitor consists of two metal plates or electrodes separated by a thin layer of aluminum oxide, typically with an alkaline electrolyte. It is this construction that gives aluminum electrolytic capacitors its superior electrical characteristics and high capacitance.

The E81D251VNN281MQ25T is a specific model of aluminum electrolytic capacitor that is designed for high-frequency applications. It has low ESR (Equivalent Series Resistance), low ESL (Equivalent Series Inductance), and high ripple current capabilities. The maximum voltage rating of this model is 250 volts and the capacitance is rated at 2.4 microfarads. The temperature range of this capacitor is -40℃ to +105℃.

The principle of operation for an aluminum electrolytic capacitor is fairly simple. When a voltage is applied, electrons from the negative plate go across the aluminum oxide layer and onto the positive plate. The electric field created by the electrons causes an oxidation process which forms the aluminum oxide layer, which is a dielectric material. This creates a capacitor’s dielectric material that can hold an electrical charge. When current from an external source is applied to the capacitor, the plate’s charges are attracted to opposite charges and a voltage gradient is created between them.

The E81D251VNN281MQ25T aluminum electrolytic capacitor is used in high-frequency applications, such as computer motherboard power supplies, inverters, audio frequency transformers, radio frequency resonators, and power supplies. It is also used in electric motors, air conditioning systems, and electric power tools. The capacitor is suitable for surface mounting and is designed for a wide range of temperatures.
