Aluminum electrolytic capacitors are polar capacitors meaning they are not suitable for AC use. They offer higher capacitance than other type of capacitors and are most common type of capacitor used for DC applications. The EGPD250ELL432MM20H aluminum electrolytic capacitor is an aluminum electrolytic capacitor from a range of products in the EGPD product family.

The EGPD250ELL432MM20H offers a high capacitance in a miniature package and is suitable for applications where space is at a premium. It is cylindrical in shape with a height of 4.3 mm and a diameter of 2.5 mm. The voltage rating is 6.3 VDC and its capacitance is 220 µF. Its equivalent series resistance (ESR) is 120 mΩ at 120 Hz.

The EGPD250ELL432MM20H capacitor is primarily used in audio, telecommunications, traffic signals, automotive, home appliances and medical equipment. It can be used for applications such as decoupling, smoothing, filtering, output coupling, time delay, oscillator, surge absorption etc.

The aluminum electrolytic capacitor is an older type of capacitor construction and consists of a solid aluminum anode foil etched into a continuous sequence of fine conductive plates separated by insulating paper sheets. The anode and paper layers form an anode-booster section while the cathode plate is usually found on the opposite side of the anode-booster. The anode plate, together with the booster, forms a polarized double-layer capacitor. The aluminum capacitor is the only type of capacitor with a significant capacity.

The working principle of aluminum electrolytic capacitor is based on the formation of a conductive electrolyte layer on the anode. An electrode and a counter-electrode are immersed in an electrolyte solution. When an electric field is applied, electrolyte ions become mobile and form a conducting layer on the anode, in between the anode and a separator. The layer has a capacitance and creates a current when the electric field is applied. The layer is also accountable for the properties of the capacitor such as the voltage rating, capacity and ESR.

The EGPD250ELL432MM20H is a type of aluminum electrolytic capacitor and is ideally suited for a range of applications which require compact size and high reliability. It is suitable for decoupling, smoothing, filtering, output coupling, time delay, oscillator, surge absorption etc. applications where a high capacitance is required in a small package.
