UKL1C221MPDANA

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in modern electronic products for a variety of purposes. From power supplies to wireless communication networks, capacitance plays an important role in achieving desired circuit operations. This article focuses on the UKL1C221MPDANA components and how they work.

Application Field

The UKL1C221MPDANA is a common choice for a variety of industrial, consumer and automotive applications. Its small size and low cost make it a great option for components that require a little additional space or cost reductions. It is suitable for low voltages from 1.5 to 16V, which makes it a great choice for many design applications.

It is a radial leaded product, meaning it is assembled directly onto a printed circuit board. The housing is made of aluminum and epoxy shrink tube, and the leads are lead-tin alloy and extend from the package for mounting. Its anodized aluminum housing is highly corrosion-resistant and provides excellent mechanical strength.

The UKL1C221MPDANA is rated for operating temperatures from -45°C to +85°C. Its ripple current ratings are 25A and 50V, making it an ideal choice for surge protection. With an operating life expectancy of more than 2000 hours, it is a reliable option for many applications.

Working Principle

Aluminum electrolytic capacitors operate on the principle of charge separation by using two aluminum foils separated with a dielectric electrolytic solution. One foil is an anode that stores positive charge. The other foil is a cathode that stores the negative charge.

The electrolytic solution is a material with a high dielectric constant and low resistance. When a voltage is applied across the two terminals of the capacitor, the electrons move onto the anode and develop an electric field on both sides of the electrolyte. This creates the ability to store a charge and is known as a capacitance.

Due to the high quality of anodized aluminum and dielectric electrolyte used, aluminum electrolytic capacitors are more reliable than other capacitor types. In addition, they have higher capacitance values and better voltage and ripple-current ratings than ceramic or plastic capacitors. These advantages make them an ideal choice for many modern electronic applications.
