UHE1V221MPD1TD Capacitors

Aluminum electrolytic capacitors, also known as aluminium electrolytic capacitors, are highly reliable and cost-effective capacitors used in various applications. The UHE1V221MPD1TD is an exemplary aluminum electrolytic capacitor offering a high-kilovolt-ampere rating and a long life expectancy. In this article, we’ll have a look at the UHE1V221MPD1TD application field and working principle.

The UHE1V221MPD1TD is designed for use in applications such as voltage multipliers, motors, relay coils, telecommunication equipment and high frequency switching applications. The capacitor offers a long-term temperature range from -55 to +125°C and three ratings, one for ripple current, one for minimum lifetime and one for minimum leakage current. Additionally, the capacitor features a bronze/copper combination terminal with nickel/steel combination clamp and is 100% tested and screened for parameters such as ESR, capacitance, insulation resistance and leakage current.

As far as the working principle of the UHE1V221MPD1TD aluminum electrolytic capacitor is concerned, it operates on the same principle as an electrolytic capacitor in general. It has a dielectric composed of aluminum oxide and is charged with an electrolyte solution such as potassium hydroxide. The aluminum oxide layer acts as a dielectric that can store electrical energy. The voltage across the capacitor is limited by the thickness of the aluminum oxide layer, which is why aluminum electrolytic capacitors have relatively high working voltages.

The capacitor also has two electrodes, the anode and the cathode. The anode is a sheet of highly porous aluminum that is usually treated with a thin layer of activated carbon material. The cathode is a sheet of conductive material, usually a metal. When the capacitor is connected to a power supply, the anode becomes positively charged and the cathode negatively charged. This creates an electric field between the two electrodes and charges the capacitor.

The capacitance of the UHE1V221MPD1TD is derived from the number and size of the tiny pores in the anode which allow electrons to flow through. The number and size of these pores determine the capacitance of the capacitor, and their structure can be altered depending on the conditions of the application. The better the design of the anode, the higher the capacitance of the capacitor.

The capacitors can be used in both DC and AC circuits. In the case of AC circuits, the capacitor acts as a filter, removing the AC ripple from the voltage. This is useful when powering devices such as LED drivers, motors and relay coils as it helps reduce power consumption and prevents the devices from being damaged by AC ripple. The capacitor has a very high surge withstand rating, which makes it suitable for use in voltage multipliers and high frequency switching applications.

To conclude, the UHE1V221MPD1TD aluminum electrolytic capacitor is a highly reliable and long-lasting solution for a wide variety of applications. It offers a high-kilovolt-ampere rating and an exceptionally long life expectancy, and its bronze/copper combination terminal with nickel/steel combination clamp makes it extremely durable. Additionally, its high surge withstand rating and its ability to operate both in DC and AC circuits make it a great choice for voltage multipliers and high frequency switching applications.
