Introduction

Aluminum Electrolytic Capacitors, or “AEC’s,” are widely used components in electrical/electronic circuits for numerous applications. The UKW2A010MDD1TD capacitor is a radial-leaded type of AEC, and its highly-popular design serves a variety of uses, from controlling the power in high frequency switching applications to providing surge protection and filtering.

Physical Construction

A physical examination of the UKW2A010MDD1TD reveals an aluminum electrolytic capacitor with a cylindrical body and radial leads located at the bottom and top of the capacitor. At the center of the capacitor is a separator, allowing charges to form both on the positive plate and the negative plate. This is held together with a lower connection plate, while the top connection plate is connected to the two leads and is connected to the upper plug.

Voltage Rating & DC Leakage

The UKW2A010MDD1TD has a voltage rating of 10,000 volts and a DC leakage current of 0.02 mA at 25°C. This leakage current is very important, as it determines the amount of current that can be conducted without fail. A low DC leakage current indicates that the capacitor is a good choice for applications in which current leakage must be controlled.

Capacitance

The UKW2A010MDD1TD boasts a capacitance of 1µF and a tolerance of ±10%. This means that the actual capacitance of the capacitor may vary slightly from the rated value, but will always remain within the ±10% tolerance margin. The capacitance of the capacitor is important, as it determines the amount of energy the capacitor can absorb and store.

Working Principle

The UKW2A010MDD1TD functions by storing electrical energy through the process of electrostatic charging. The capacitor consists of two metal plates that are separated by an insulator known as a dielectric. When a voltage is applied to the capacitor, electrons are attracted to one of the metal plates, creating a negative charge. This charge induces a positive charge on the other metal plate, creating an electric field between them. This field causes the capacitor to store electrical energy until the voltage is removed from the capacitor.

Application Field

The UKW2A010MDD1TD capacitor is ideally suited for use in multiple power applications. These include:

• Lighting ballasts;
• Switched power supplies;
• Motor speed controllers;
• Voltage regulators;
• Load and line filtering;
• Surge and overvoltage protection.

The UKW2A010MDD1TD is also widely used in the telecommunications and computer industries as a means of ensuring reliable operation of systems.

Conclusion

The UKW2A010MDD1TD capacitor is an example of the modern generation of Aluminum Electrolytic Capacitors. Its highly tolerant design, low DC leakage characteristic, and 1µF capacitance makes it ideal for a variety of power applications, from filtering to surge protection. With its wide range of application potential, the UKW2A010MDD1TD represents a versatile and reliable choice for many power circuits.
