Frequently Asked Questions
What are the capacitance and voltage ratings of the Nichicon UVY1H222MHD?
The UVY1H222MHD is rated at 2200 µF capacitance and 50 V working voltage, making it a high-capacity bulk electrolytic capacitor. This combination provides sufficient energy storage for smoothing 50 Hz or 60 Hz rectified AC supplies in linear power supplies and for handling load transients in switching regulators with output voltages from 12 V to 48 V range designs.
How does the 16 mm diameter of UVY1H222MHD affect PCB footprint and layout planning?
The 16 mm body diameter requires a corresponding PCB land pattern with adequate pad spacing for the radial leads, typically 7.5 mm lead pitch for this size range. Designers must also reserve 16 mm of board area and sufficient height clearance in the enclosure, as radial electrolytic capacitors of this size can stand 25 mm to 35 mm tall. Panelized assemblies should verify that adjacent components maintain at least 2 mm clearance around the capacitor body.
What is the maximum leakage current specification and why does it matter in low-power designs?
The UVY1H222MHD specifies a maximum leakage current of 3.3 mA. In battery-powered or low-standby designs, leakage current from large electrolytic capacitors contributes directly to idle power consumption. At 3.3 mA across 50 V, this represents up to 165 mW of standby loss, which is significant in portable or energy-efficient equipment. Designers targeting sub-100 mW standby power should consider this in their power budget.
In what type of power supply filtering is the UVY1H222MHD most effective?
The UVY1H222MHD is most effective as a bulk filter capacitor on the DC output of full-wave bridge rectifiers in linear power supplies operating at 50 V or below. At 2200 µF, it reduces ripple voltage by storing charge during each rectifier conduction interval. For a 1 A load current at 50 Hz, 2200 µF limits peak-to-peak ripple to approximately 9 mV across a well-designed filter stage, meeting the noise requirements of most analog and power amplifier circuits.
