UTM1A221MPD

Aluminum electrolytic capacitors, or “super capacitors” as they are sometimes referred to, are one of the most widely used and versatile components in electronic circuits. Originally developed in the 1950s, these components have become instrumental in many applications due to their excellent performance characteristics, low cost, and long life.

UTM1A221MPD aluminum electrolytic capacitors are a type of aluminum electrolytic capacitor that combines the advantages of a solid-state capacitor and a conventional aluminum electrolytic capacitor in a single device. This capacitor features a large capacitance combined with low equivalent series resistance (ESR). This combination of features is ideal for high current applications, such as in power supplies, voltage regulators, and UPS systems. UTM1A221MPD aluminum electrolytic capacitors also have a very low voltage coefficient, which makes them suitable for use in high voltage applications.

The construction of a UTM1A221MPD aluminum electrolytic capacitor begins with a core made of an aluminum anode plate and a dielectric material layer that is sealed in a metal can. A cathode foil is crimped to the anode plate, and a plastic end seal is used to protect the inner components from dust, moisture, and other environmental factors. The metal can also functions as the cathode plate. Electrons will flow to the anode plate where they will be stored, and the capacitor will discharge when a voltage is applied.

The performance characteristics of the UTM1A221MPD aluminum electrolytic capacitor depend on the construction and design of the component. These capacitors have a leakage current of 2.5µA, a voltage-to-capacitance ratio (VCR) of up to 20V, and an insulation resistance of up to 15M ohms. They also feature a low ESR of 0.15mA and a low thermal impedance of 1.0K/W at 25°C, making them suitable for use in high frequency applications.

The UTM1A221MPD aluminum electrolytic capacitor is the ideal solution for applications such as power supplies, UPS systems, and voltage regulators. Its large capacitance combined with a low ESR makes it suitable for high power applications. Its low voltage coefficient, low leakage current, low thermal impedance, and high insulation resistance make it suitable for use in high voltage applications. These characteristics, combined with its long life and low cost make it a popular choice for many applications.
