Aluminum electrolytic capacitors have a long history of achieving efficient performance and improved durability in a variety of applications. UVR1A221MED1TD is a radial aluminum electrolytic capacitor of the Snap-In type, with a lifetime of up to 1,000 hours. It is widely used in a variety of power supplies and other power electronics applications, including electrostatic accelerators, inverters, and bipolar amplifiers, where superior high frequency operation is required. This capacitor is especially suitable for applications requiring low inductance operation and reliable long-term performance.

UVR1A221MED1TD aluminum electrolytic capacitors feature a nonlinear, thick-electrolyte design that makes them very durable and resistant to mechanical shock. The insulating materials used are also heavily baked and are composed of high-purity aluminum foils, enabling them to work well even in highly charged environments. Furthermore, this type of capacitor achieves excellent volumetric efficiency and offers a significantly lower effective series inductance (ESL) than traditional snap-in designs.

The construction of UVR1A221MED1TD aluminum electrolytic capacitors is designed to maximize the efficiency of their operation. The capacitance is spread across the surface of the aluminum foils, allowing for a greater capacitance per unit volume and a greater efficiency. Also, the aluminum foils are plated with a thin dielectric coating that prevents their surfaces from corroding and helps to minimize dielectric absorption losses. Finally, this capacitor also has a low self-discharge rate, which is beneficial in high-power applications.

The working principle of UVR1A221MED1TD aluminum electrolytic capacitors is based on the principle of capacitance. When an electrical potential is applied between two plates of this type of capacitor, the electric field will induce an opposite charge on each plate. This opposite charge will then create a capacitive current that will be proportional to the voltage applied to the capacitor. This current will then be forced through the electrolyte in the capacitor and will cause a decrease in the active-electrolyte voltage, resulting in a higher energy storage capacity.

UVR1A221MED1TD aluminum electrolytic capacitors are widely used in various power supplies and other power electronics applications, such as electrostatic accelerators, inverters, and bipolar amplifiers. They are particularly suitable for applications requiring low inductance operation and highly reliable performance. These components offer excellent volumetric efficiency, making them a popular choice for applications requiring high capacitance in a small package. Furthermore, their thick-electrolyte design and heavy baking make them durable and resistant to mechanical shock.
