Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, commonly known as electrolytic or polar capacitors, are a type of capacitor that uses aluminum oxide as the dielectric material and uses an electrolyte such as electrolyte salt water or a conducting organic solvent as the the medium. These capacitors are typically divided into two categories: Aluminum Electrolytic Capacitors (AECs) and Aluminum Electrolytic Polar Capacitors (AEPCs).

UHE1A822MHD6 Application Field and Working Principle

The UHE1A822MHD6 capacitor is an aluminum electrolytic capacitor with a capacitance of 220 µF. It is most commonly used in circuits found in audio and audio-video systems. It is designed for applications where a large capacitance is required in a small space.

The UHE1A822MHD6 works by using an electrolytic medium (typically a conductive saltwater-based solution) between two metallic electrodes. One electrode is made of aluminum while the other is made of a conductive material such as silver, nickel, copper, etc. When a voltage is applied to the two electrodes, a dielectric layer of aluminum oxide is formed between them. This oxide layer increases the capacitance of the device and also serves as a barrier to prevent the current from flowing between the two electrodes.

The UHE1A822MHD6 capacitor can operate from -25°C to +85°C and has a voltage rating of 50V DC. It is also resistant to vibration and has an extended lifespan, even in high temperature or humid environments. Its advantages include high capacitance in a small size, high insulation resistance, excellent electrical characteristics, low equivalent series resistance (ESR), and low leakage current.

This capacitor has a wide range of applications, such as power supplies, filters, high-frequency circuits, switching applications, and high-precision electronic circuits. It is also suitable for use in medical devices and motor control circuits. Due to its small size, it is often used in portable electronic devices such as smartphones and tablets.
