Aluminum electrolytic capacitors are widely used capacitors in electronic circuits, and they are usually based on a design of two aluminum foils with anode and cathode winding assembly, and with an electrolyte-soaked paper separator between them. The EDH107M025A9MAA is one of such capacitors, and this article will cover its applications, working principle and specifications.

Applications

The EDH107M025A9MAA is a high-performance aluminum electrolytic capacitor, with an operating temperature range of -40°C to 105°C, and a rated voltage of 25V. It is suitable for a wide range of applications, and is well-suited for digital or desktop PC power supply, LCD monitors, and medical instrumentation.

It is also suitable for industrial, instrumentation, and switching mode power supplies, as well as automotive, telecommunications, and mobile audio systems. Additionally, it is recommended for use in stabilizing DC-DC converters, clock circuits, and power supplies.

Working principle

The EDH107M025A9MAA is a polarized capacitor, which means that one of its two terminals must be connected to a positive terminal, with the other terminal connected to a negative terminal. When the capacitor is connected to a power source, the two terminals act as the anode and cathode, respectively.

When the capacitor is charged, electrons flow from the anode to the cathode, producing a charge. This charge is stored within the capacitor due to the presence of the electrolyte-soaked paper separator between the two aluminum foils. When the capacitor is connected to a load, the capacitor’s ability to store the charge is used to provide the power required for the load.
