Additionally, the UHW1C222MHD capacitor offers excellent ESR performance and high capacitance stability over a wide temperature range.

The UHW1C222MHD capacitor is ideal for decoupling, filtering, and for use in protection circuits, low pass filter networks, and high frequency switching power supplies. The capacitor is rated for working temperatures from -40C to +85C, making it an ideal choice in many applications, such as medical and automotive electronics, where tight controlled temperatures are required. The capacitor is also RoHS compliant, so it is suitable for use in products destined for European markets.

Working Principle

The UHW1C222MHD aluminum electrolytic capacitor is an electrolytic capacitor that utilizes a capacitor element consisting of an oxide film on aluminum foil, which is impregnated with an electrolyte and sealed with a non-porous plastic case. When two of these elements are electrically connected, one positive and one negative, a static electrical field is created between them in which electrical charge is stored. When current is applied, the electrical field distributes the electric charge onto the two electrodes and the capacitor is said to charge. When the voltage across the capacitor falls, the electric field dissipates, leaving the capacitor in a discharged state.

The high storage capacity and high voltage capability of the UHW1C222MHD aluminum electrolytic capacitor is due to the thin and highly conductive oxide film on the aluminum foils. This thin oxide layer increases the overall efficiency and performance of the capacitor. Additionally, the good capacitance stability of the capacitor over a wide temperature range is due to its impregnated electrolyte and the design of the capacitor element.

Conclusion

The UHW1C222MHD by Nichicon is a high quality aluminum electrolytic capacitor. It is designed with a large capacity and voltage capability, making it suitable for power supplies, filtering and protection applications. Additionally, the capacitor offers excellent ESR performance and high capacitance stability over a wide temperature range. Due to these advantages and its RoHS compliance, the UHW1C222MHD aluminum electrolytic capacitor is an ideal choice in many applications.
