Aluminum Electrolytic Capacitors are the most commonly used type of capacitor. They are widely used in telecommunications applications, computers, and consumer electronics. The EEU-HD1HR22B is a high-reliability aluminum electrolytic capacitor that is designed for use in demanding applications. It features an extended temperature range, higher ESR, and lower ESL than other aluminum electrolytic capacitors.

The EEU-HD1HR22B features an anodized aluminum case and a polypropylene capacitor element. The aluminum case has a high dielectric strength of more than 5 kilovolts, and the polypropylene capacitor element is designed for long-term reliability and durability. This capacitor is rated for a capacitance of 10 μF to 100 μF, and for operating temperatures ranging from -55°C to +105°C.

The working principle of aluminum electrolytic capacitors is based on separation of two metal plates. One of the plates is an anodized aluminum case and the other is a thin dielectric layer. The dielectric layer is formed by electrolyte soaked in an electrolytic solution, typically a water-based solution. A metallic foil-like coating is then applied to the opposite face of the capacitor. This process creates an electric field between the metallic foil-like coating and the electrode. As a result, a current (charge) is generated and stored between the two electrodes, allowing the capacitor to act as an energy storage device.

The EEU-HD1HR22B is suitable for a variety of applications, including power supply filtering, coupling, and decoupling circuits. It can also be used as a noise filter in analog circuits to suppress interference, or as a transient voltage suppressor to absorb large voltages. Additionally, this capacitor is suitable for ultra-low temperature and high frequency applications. It is designed to provide stable performance and reliability over a wide range of temperatures and frequencies.

In summary, the EEU-HD1HR22B is a reliable choice of aluminum electrolytic capacitor, suitable for use in a variety of applications. It features a high dielectric strength, long-term reliability, and stable performance. The capacitor works on the principle of separation of two metal plates, which creates an electric field between the metallic foil-like coating and the electrode. This allows the capacitor to act as an energy storage device, suitable for many demanding applications.
