Aluminum electrolytic capacitors, also known as electrolytic capacitors, are polarized capacitors and one of the most widely used capacitors. They generally consist of an anode made of aluminum foil, a dielectric oxides film formed on the anode foil surface, a catode made of aluminum foil or a paper impregnated with a highly conductive electrolyte, and a sealing case. The UPM1H120MDD is one type of aluminum electrolytic capacitor.

The main application field of the UPM1H120MDD aluminum electrolytic capacitor is in DC line filtering, providing a good filtering effect and greatly reducing the noise inherent in electrical circuits. Additionally, the UPM1H120MDD has a wide temperature range, from -55 to +105 degrees Celsius, and good durability, with a long useful life up to 2000 hours at +105 degrees Celsius temperature. Besides, this aluminum electrolytic capacitor has a high insulation resistance and a wide capacitance range.

The working principle of a UPM1H120MDD aluminum electrolytic capacitor is similar to that of other electrolytic capacitors. It features a thin oxide "dielectric" layer deposited on an aluminum plate. The dielectric layer acts like a barrier and stores positive charge on one surface and negative charge on the other. This creates a potential difference between the two sides. When a voltage is applied across the terminals of the UPM1H120MDD aluminum electrolytic capacitor, an electric field is formed and the capacitance increases, allowing current to flow through it. At the same time, it acts as an energy storage device.

For most electronic applications, the UPM1H120MDD aluminum electrolytic capacitor performance is very good, especially when it comes to low-frequency filtering and high-temperature operation. It has a low overall equivalent series resistance (ESR), which is beneficial for removing noise and supplying energy to high-load components. Additionally, it also features good thermal stability, which is especially important in high-temperature-resistant applications.

In summary, the UPM1H120MDD aluminum electrolytic capacitor provides excellent stability and reliability in a variety of applications. It is widely used in automotive, computer, medical and other industries due to its versatile and long-lasting design. The aluminum electrolytic capacitor is one of the most popular types of capacitors due to its benefits and reliable performance.
