Aluminum Electrolytic Capacitors are widely used in many fields and have many different models. EDH225M050A9BAA is one of them. This article will introduce the application field and working principle of EDH225M050A9BAA.

Application field of EDH225M050A9BAA

EDH225M050A9BAA belongs to non-solid aluminum electrolytic capacitors, and its capacitance is 22.5mF (at rated voltage of 25V). With low ESR and high capacitance, EDH225M050A9BAA is mostly used as power supplies in many different fields. Here are some common applications of EDH225M050A9BAA:

• It can be used as a main filter capacitor on the power input side of various electronic equipment and AC adapters.
• It can be used as a starting device and ballast capacitor in fluorescent light.
• It can be used as a high-frequency bypass capacitor and power supply bypass of OA equipment, such as printers and copiers.
• It can be used as a boost capacitor and pre-charging capacitor in commercial inverters.
• EDH225M050A9BAA can also be used in the transformer secondary circuit and the pump motor.

In brief, EDH225M050A9BAA is low loss and low impedance, and it has good heat dissipation and small volume, so it is mostly used as filtering components in various AC and DC switching power supplies. And, since it is polarized and can not withstand reverse connection, it must be tested and characterized according to the actual application environment.

Working principle of EDH225M050A9BAA

The working principle of EDH225M050A9BAA is based on the electrochemical properties of aluminum. Aluminum Electrolytic Capacitors are composed of anode and cathode aluminum foils, aluminum oxide film, separator and electrolyte. When a positive voltage is applied to the positive electrode, the electrolyte enters into the anode foil and forms a thin oxide film on the surface of the anode foil. This film is an insulator which separates the positive and negative electrodes. As the applied voltage increases, the capacitance value also increases until it reaches its limit and the capacitance is sufficient to bypass the alternating current.

When it is discharged, the charge is negative, and the electrons of the negative electrode enter the electrolyte, reducing the oxide film of the anode and increasing the capacitance. The opposite is true for discharge.

The aluminum electrolytic capacitors have very small loss and very high ripple current. Generally, they are used in the filter circuit of the DC power supply and switch power supply. Its advantage is that it can reach very high capacitance value, while its disadvantage is that its life is relatively short.
