Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitor that use an electrolyte and a porous oxide-coated anode in order to facilitate the flow of electrons through the device. They are suitable for applications requiring high capacitance, such as energy storage, high-frequency AC applications, and DC/AC rectifiers circuits. The porous nature of the anode allows for a relatively large surface area in a compact device, allowing for the highest capacitance values for a given volume.

The MAL209679561E3 aluminum electrolytic capacitor is a cylindrical, 3-terminal device with a rated operational voltage of 25VDC and a maximum operating voltage of 50VDC. It offers a maximum rated capacitance of 500μF and a maximum equivalent series resistance of 135mΩ. The operating temperature range is -40°C to 85°C and the capacitance retention is ±20% at 85°C for 2000 hours.

Application Field

The MAL209679561E3 aluminum electrolytic capacitor is suitable for use in high-frequency AC circuits such as rectifiers, switching power supplies, power factor correction, and DC/AC inverter circuits. It is also suitable for applications involving high-energy storage, such as energy storage devices and electrolytic corrosion protection devices. It is also suitable for use in audio circuits, motor control circuits, and automotive power supplies.

Working Principle

The MAL209679561E3 aluminum electrolytic capacitor works on a principle known as \'Double-Layer Capacitance\'. This principle is based on the formation of two layers of charge on the opposite surfaces of the electrolyte - the anode and the cathode. When a voltage is applied to the capacitor, the electric field enables charge flow from one layer to the other. This charge movement forms an electric field which is opposed to the applied voltage, thereby providing capacitance. The capacitance is determined by the area of the charge layers, their relative separation, and the type and amount of electrolyte.

The MAL209679561E3 aluminum electrolytic capacitor provides a high capacitance value in a compact size, making it ideal for applications requiring high capacitance. The device is also low in ESR, meaning it can handle high current spikes with minimal voltage drop.

In conclusion, the MAL209679561E3 aluminum electrolytic capacitor is a high performance capacitor suitable for a wide range of applications. Its high capacitance and low ESR make it ideal for high-frequency AC circuits, energy storage devices, and motor control applications.
