EEU-HD1E221B Capacitors

Aluminum electrolytic capacitors, also known as Electrolytic capacitors, are capacitors that use aluminum oxide as the dielectric material. The EEU-HD1E221B is an aluminum electrolytic capacitor typically used in applications where high volumetric efficiency is required. Additionally, this type of capacitor also offers a wide temperature range, excellent ripple current characteristics, and a long life cycle.

The working principle of an aluminum electrolytic capacitor is based on the physical phenomenon known as the formation of an electric double layer at the interface between a conductive and an insulating material subjected to an electric field. When a voltage is applied across an anode and a cathode separated by a semiconductor material, an electric double layer is formed by an accumulation of positive ions near the anode and negative ions near the cathode. This electric double layer forms a capacitor with a dielectric constant of more than one.

The EEU-HD1E221B aluminum electrolytic capacitors are commonly used for applications where large capacitance values, in a relatively small size, are required. The EEU-HD1E221B capacitors are especially suitable for power supply, DC-DC converter, charger, AC adapter, and inverter applications. In AC adapter applications, they are typically used as a start-up, power supply, ripple-reducing, bypass, or filter capacitor, while in inverter applications they are typically used as an output filter capacitor.

The EEU-HD1E221B aluminum electrolytic capacitor offers several advantages over other types of capacitors such as tantalum or ceramic. They are capable of providing high capacitance (up to 1000 microfarads), have low equivalent series resistance (ESR, less than 0.1 ohms for a 10 microfarads capacitor), and low equivalent series inductance (ESL, less than 0.6 nH for a 10 microfarads capacitor). They are also able to provide high ripple currents, high temperature stability, and long life expectancy (up to 2000 hours). This makes them an ideal choice for power supply applications.

In addition to their high capacitance and ripple current characteristics, the EEU-HD1E221B aluminum electrolytic capacitors offer several other benefits. They are available in a variety of packages, including radial, snap-in, and surface mount styles. They have a wide range of capacitance values, from 3.3 microfarads to 1000 microfarads, and a wide operating temperature range from -25°C to +105°C, making them suitable for a variety of applications. Additionally, they have a very low leakage current and can operate at high frequencies. All this makes them an ideal choice for power supply and other high-voltage applications.

In summary, the EEU-HD1E221B aluminum electrolytic capacitor is an ideal choice for applications where high volumetric efficiency, high capacitance values, and long life expectancy are required. They are widely used in power supply, DC-DC converters, charger, AC adapter, and inverter applications. They offer low ESR and ESL, high ripple currents, a wide operating temperature range, and much more.
