EGXE100ELL221MH12D

Aluminum electrolytic capacitors, often referred to as electrolytic capacitors, are widely used in circuit boards and are a common type of capacitor.

The general Aluminum electrolytic caps consists of two electrodes, a foil and a diaphragm. One side of the diaphragm is connected with a tab and the other side is connected with a lead, the lead is connected with the outer casing of the cap. The inner foil is a corrosion-resistant aluminum foil, with a large number of etched holes. The diaphragm is a thin sheet of electrolyte-soaked paper, which provides a dielectric layer between the two electrodes. The outer casing of the cap is usually made of metal and serves as a second terminal.

The EGXE100ELL221MH12D aluminum electrolytic capacitor is suitable for applications such as electric vehicles and power systems. The cap has a maximum operating temperature of 125°C, working voltage of 100V, electrolytic volume of 221μF, rated ripple current of 9500A, and excellent self-healing properties. In terms of design and construction, the cap features improved mechanical strength and eutectic solder processing.

The working principle of an aluminum electrolytic capacitor is based on the flow of electric current. When a voltage is applied between the electrodes of the cap, the aluminum foil becomes positively charged, while the anodic paper becomes negatively charged. This creates a positive-negative electric field which attracts electrons. The electrons are then drawn through the paper and onto the aluminum foil, where they build up a layer of metal oxide. This buildup of electrons creates an interior electric field and a capacitance.

The EGXE100ELL221MH12D aluminum electrolytic capacitor has an impedance of 11KΩ, resonance frequency of 100kHz, dielectric strength of 1000KV/m, and an electrode area of 157mm². These properties make it ideal for applications where noise-free performance and high-temperature resistance are needed.

In conclusion, the EGXE100ELL221MH12D aluminum electrolytic capacitor is a versatile and robust capacitor, suitable for electric vehicles and power systems. Its high temperature resistance, durable construction, and improved mechanical strength make it ideal for a wide range of applications.
