Aluminum electrolytic capacitors are widely used in electronic circuits because of their high capacitance per unit volume. The UVZ1H220MDH capacitor is no exception, as it is a radial leaded, chip-style aluminum electrolytic capacitor that is typically used in noise filtering or as a buffer in power supplies. It also offers superior performance when used in high frequency switching applications.

The working principle of aluminum electrolytic capacitors lies in the chemical reaction between the aluminum anode and the electrolyte. The anode is usually composed of an aluminum foil embedded in a paper separator saturated with an electrolytic solution. The cathode is also usually composed of an aluminum foil. When a voltage difference is applied between the anode and the cathode, the electrolytic solution causes a reaction to take place between the two foils, forming a thin film of aluminum oxide on the anode surface. This acts as a dielectric between the anode and the cathode, creating a capacitance. This principle is known as the Faraday principle or surface-oxide layer capacitance.

The UVZ1H220MDH aluminum electrolytic capacitor has a working voltage of 220V DC, a capacitance of 22uf, a capacitance tolerance of ± 20%, a leakage current of 0.07CV or less, an operating temperature range of -40°C to +85°C and a rated lifetime of 2000 hours. With its relatively low ESR, and wide temperature range, it is suitable for use in power applications, as well as in small, low-power circuits.

The UVZ1H220MDH aluminum electrolytic capacitor is used in a variety of applications, including power tool motors, communication equipment, medical equipment, automotive electronics, home appliances, and HVAC (heating, ventilation, air conditioning) systems. It can also be used in AC/DC circuits and in stabilizing circuits. Its superior dielectric properties make it an ideal choice for use in filtering, bypassing, and buffering applications.

The UVZ1H220MDH aluminum electrolytic capacitor has excellent temperature stability, high self-healing performance, and a long service life. It is small in size and lightweight, making it an ideal choice for use in tight installations and for applications where space is limited.
