Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are among the most widely used general-purpose capacitors in the electronics industry. They are not the most stable from a temperature and performance standpoint, but their advantages in terms of voltage and temperature range have made them an indispensable part of most circuit designs.

Given their wide range of performance, aluminum electrolytic capacitors are suitable for a variety of applications in different industries. In consumer electronics, their most common applications include bypassing, coupling, decoupling, filtering, bypassing, and DC blocking. In more industrial applications, such as motor drives, light dimming, power supplies, and UPS systems, they serve numerous functions.

The UPW1H220MDH is a common type of aluminum electrolytic capacitor. It is a non-polarized, radial aluminum electrolytic capacitor used for both low and high frequency applications. It is well suited for bypass, decoupling, and AC blocking applications.

The UPW1H220MDH has a solid electrolyte construction, which means that the individual components of the capacitor are a sealed unit and therefore pressure-resistant. This makes the capacitor resilient to shock and vibration, as well as temperature changes, which is ideal for industrial applications. It is rated up to 85°C and has an operating temperature range of -25-85°C.

The capacitor is also capable of withstanding extreme voltages and providing stable capacitance values. It is rated for higher voltage (2000V DC), withstanding up to 5000 hours at 500V DC. It also has a wide capacitance range of 0.47uF - 470uF and a wide temperature range of -25 − 85°C.

The UPW1H220MDH has one lead terminal that allows for direct connection of the capacitor to the circuit board and is solderable for easy assembly. The solid electrolyte construction also ensures an extended useful lifetime and high reliability.

The UPW1H220MDH works on the principle of electrostatic discharge. By providing a low resistance path for electrical current, the capacitor acts like a short-circuit between two electrodes. When current passes through the capacitor, an electric field is created in the dielectric material (the capacitor’s electrolyte) that stores charge and causes a voltage difference across the two electrodes.

This electric field prevents the flow of current and stores energy. Thus, when a voltage is applied to the two electrodes, the stored energy is released in the form of current. When the current ceases, the electric field stored in the capacitor dissipates and the capacitor returns to its original state.

The UPW1H220MDH capacitor is a versatile component that makes a great addition to any circuit. Its rugged construction and wide temperature range make it ideal for a variety of industrial applications, while its low ESR makes it perfect for use in filtering and bypassing. And with a high voltage rating and long service life, the UPW1H220MDH is a component you can count on.
