Overview of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors have become essential for power management in many consumer and industrial electronic applications. Their performance and reliability, combined with their small size and low cost, have made electrolytic capacitors indispensable components in electronics today.

UKL1E221KPD1TD Application Field and Working Principle

The UKL1E221KPD1TD is an aluminium electrolytic capacitor designed with both polarised electrodes and radial leads. This capacitor has a wide range of applications, including computers, medical equipment, telecommunications, automotive electronics, and general industrial equipment. A capacitor is an electrical component that stores energy and is composed of two metal plates separated by a dielectric material, such as glass, plastic, or paper. In an electrolytic capacitor, an electrolyte is used instead of the dielectric material. This electrolyte is a solution containing dissolved electrolytes, usually taken from a mixture of acids. The metal plates in an electrolytic capacitor are coated in a layer of a conductive material, called the electrolyte. The metal plates act as two poles; one negative and one positive. The working principle of an electrolytic capacitor is based on the idea of an electric double layer. When an electric field is applied to the two metal plates in an electrolytic capacitor, a layer of positive ions from the electrolyte forms on the negative plate and a layer of negative ions from the electrolyte forms on the positive plate. These two layers together form the charge stored on a capacitor, also called the electric double layer. This electric double layer is what allows a capacitor to store energy. The UKL1E221KPD1TD has a capacitance of 220uF, a tolerance of ±20%, a temperature range of -55°C to +105°C, and a rated voltage of 16V. It also has a tolerance of 6% per every −55R̊C - 25°C variation, which makes it well suited for applications that require reliable and stable performance in a wide range of temperatures. This capacitor can also be used in many different circuits, including DC bias and AC filtering circuits.

Benefits of the UKL1E221KPD1TD

The UKL1E221KPD1TD offers several benefits over traditional capacitors, including a smaller size and lower cost. The electrolytic capacitor’s small size allows for more efficient board design, while its low cost makes it an economical choice for applications requiring many capacitors. The UKL1E221KPD1TD also has a high capacitance for its size, which allows it to store more energy for its size than conventional capacitors. Additionally, its electrode structures also have a high conductivity, which ensures a low internal resistance. The combination of these two features allows for high currents to be handled with little to no power loss. This makes the UKL1E221KPD1TD well suited for applications that require high instantaneous currents. Finally, the UKL1E221KPD1TD has a long life span. With a 1000 hour operational life, it can continue to work reliably for many years, making it an ideal choice for applications requiring a long service life.

Conclusion

The UKL1E221KPD1TD aluminum electrolytic capacitor is a small, reliable, and cost-effective solution for many different types of electronics applications. Its small size, high capacitance, low internal resistance, and long operational life make it an ideal choice for applications that require a reliable and low-cost solution.
