Aluminum Electrolytic Capacitors are an essential component of today\'s electrical system – they are used for a wide variety of applications and can become a critical part of any equipment. One of the most popular aluminum electrolytics is the EGPD800ELL361MU20H – these capacitors are specifically designed for DC-Link circuits to provide high reliability and performance.

The EGPD800ELL361MU20H capacitor is a polarized aluminum electrolytic capacitor with a voltage rating of 630volts and a temperature range from -55°C to + 85°C. The capacitor comes with either an axial or a radial lead. The caps are offered in aluminum cases with a GEL and HDG (High Density Glass) termination and designed with an additional protective coating mechanism to enhance surge performance.

As for the capacitor application field, this type of aluminum electrolytic capacitor is mainly used for power converters, uninterruptible power supply systems, wind and solar power, UPS, motor driver, switch mode power supply, audio, and dc-ups.

The EGPD800ELL361MU20H is a non-solid aluminum electrolytic that has two elements, one being electrolytic and the other solid, that are suspended in an electrolytic solution. The solid element is made of aluminum foil, typically with a thin layer of oxide. The electrolyte is mainly an aqueous solution of potassium hydroxide, with a small amount of other ions (such as zinc sulfate, boron trifluoride, and cobalt chloride) that act as activators.

The capacitor has two electrodes – the anode being made of the electrolytic foil and the cathode made of the solid element. When a voltage is applied, the solid element gets oxidized and becomes a thin aluminum oxide. This results in a charge storage layer between the two electrodes, and the larger the surface area the higher the capacitance. The electrolyte solution also plays an important role, it acts as an insulator that ensures that only the electrons in the capacitor can move across the dielectric layer, resulting in a much higher capacitance.

The working principle of the EGPD800ELL361MU20H is very simple – when a voltage is applied, the electrons (which are negatively charged) move from the anode (positively charged) to the cathode (negatively charged). This process creates an electric field within the capacitor, which is capable of exerting a force on any charged particle that comes in contact with it. This electric field causes the electrons to become attracted and repelled from the two electrodes, generating a charge across the capacitor.

The charge stored in the capacitor is proportional to the area of the electrodes, the thickness of the dielectric layer, and the voltage applied. As the charge builds up, the amount of current that can flow through the capacitor increases until it reaches its maximum current, known as the rated ripple current. Once the maximum current is reached, the capacitor starts to discharge and the process is repeated as long as there is a voltage applied.

In conclusion, this versatile aluminum electrolytic capacitor – the EGPD800ELL361MU20H – has been specially designed for DC-Link circuits and is mainly used for the purposes of power conversion, UPS, motor driver, switch mode power supply, audio, and dc-ups. The working principle of the capacitor is simple – when a voltage is applied, it generates an electric field which allows for the accumulation of charge between the two electrodes and consequently increases the current that can flow through.
