This capacitor comes with a high voltage rating of 10V to 200V, and can easily handle the high voltage stresses present in a wide variety of device. It has low external leakage and low ESR making it an ideal choice for high precision applications.

These capacitors have a low failure rate, and they are able to operate in temperatures ranging from -40°C to +105°C. They can also handle high ripple currents at low temperatures without breakdown. Overall, these characteristics make the UVZ1A220MDH suitable for use in demanding environments.

Working Principle

The UVZ1A220MDH utilizes an aluminum electrolytic to provide a static electric charge. This is done through a process known as a Faraday-effect. The polarized electrolyte of the capacitor interacts with the static electric field created by the positive voltage applied across the terminals of the capacitor core. This causes the molecules of the electrolyte to rearrange themselves, allowing the capacitor to store an electrical charge.

The dielectric of the capacitor is formed by a thin layer of oxide that coats the electrodes. This oxide layer is called the dielectric, and it helps to provide insulation between the capacitor electrodes. The dielectric provides an important layer that prevents shorts between the electrodes, allowing the capacitor to store energy.

The UVZ1A220MDH also uses a highly efficient conductive polymer film as its cathode. This material helps to reduce the ESR values of the capacitor, making it more efficient and reliable. The combination of these materials enables the UVZ1A220MDH to provide increased capacitance and energy storage per unit volume, as well as low leakage and high ripple performance.

Conclusion

The UVZ1A220MDH is a popular choice of aluminum electrolytic capacitor, which is commonly used in a variety of electronic devices. It provides a high voltage rating of 10V to 200V, has low external leakage and low ESR, and also operates in temperatures ranging from -40°C to +105°C. Additionally, it uses an efficient conductive polymer film as its cathode, and is highly efficient in terms of capacitance and energy storage.
