Aluminum electrolytic capacitors, sometimes referred to as aluminum electrolytics, are capacitors that use aluminum as their main dielectric. The alloy is used in the construction of the capacitor to provide a high capacitance, low ESL, and low ESR. The \'EDH476M025S9HAA\' aluminum electrolytic capacitor is a high-performance, radial leaded cap that is designed primarily for use in aerospace and defense applications.

This capacitor packs an impressive 47 microfarad capacitance and an operating temperature range of −55/+125°C in a relatively small 7.5mm x 15.6mm package. It also has a rated voltage of 25 volts and a ripple current rating of 75mA. The capacitor’s construction not only ensures a long operating life, but also offers high performance and reliability with a low amount of pre-capacitance change and low inductance.

The primary application of EDH476M025S9HAA is in aerospace, defense, and industrial computing equipment. In these applications, it is used in applications where high-capacitance, low ESR, and long operating life are required. Examples include decoupling and bulk storage applications, signal filtering applications, and high-performance power supply designs. The capacitor is also suitable for use in motor control circuits, telecommunication equipment, and instrumentation applications.

Aluminum electrolytic capacitors, such as EDH476M025S9HAA, work by coating the inside of an aluminum can with an electrolytic layer of aluminum oxide. This creates an electrical barrier between the positive and negative terminals of the capacitor, providing storage of charge and a variety of filtering functions. This layer also allows electrons to pass more easily between the terminals, enabling the capacitor to store electrical energy.

The capacitance of an aluminum electrolytic capacitor is established by the area of the aluminum plate that is coated with the oxide layer. The greater the area of the coating, the greater the capacitance, up to the maximum level of the capacitor’s rating. The voltage rating of an aluminum electrolytic capacitor is limited by the breakdown voltage of the oxide layer, which is determined by the thickness of the oxide layer. This thickness can be varied to increase the voltage rating of the capacitor.

The EDH476M025S9HAA aluminum electrolytic capacitor is a reliable, high-performance capacitor designed for demanding aerospace and defense applications. Its high capacitance, low ESR, and long operating life make it an ideal choice for high-performance power supply designs, motor control circuits, decoupling applications, and more.
