Applications
The UVY1E221MED1TD is commonly used as a bulk decoupling and energy storage capacitor in linear and switching power supply output stages, audio amplifier bias networks, and motor driver boards. Its 220 µF at 25 V rating handles ripple currents from rectified AC supplies and DC-DC converter outputs in a 6.3 mm diameter footprint that fits standard PCB through-hole grids. Engineers select it for household appliances, industrial sensor power rails, and consumer electronics where compact radial capacitors with low leakage are required.

Frequently Asked Questions
What are the capacitance, voltage rating, and physical dimensions of the UVY1E221MED1TD?
The UVY1E221MED1TD is rated at 220 µF and 25 V (working voltage) with a 6.3 mm body diameter in a radial through-hole configuration. Its leakage current is 0.165 mA, and the aluminum wet electrolytic construction ensures stable capacitance across typical operating temperature ranges found in consumer and industrial applications.
How does the UVY1E221MED1TD perform as an output filter capacitor in a 5 V switching regulator design?
With 220 µF of capacitance at a 25 V rating, the UVY1E221MED1TD provides substantial hold-up energy and ripple attenuation on a 5 V DC bus, reducing output ripple voltage by up to 90% in a typical 1 A buck converter stage. Its through-hole 6.3 mm radial package withstands the mechanical stress of wave soldering and accommodates capacitor ESR-sensitive inductor-capacitor filter networks operating at switching frequencies from 50 kHz to 500 kHz.
Is the UVY1E221MED1TD suitable for audio power supply bypass applications, and what makes it preferable to ceramic capacitors at 220 µF?
Yes, the 220 µF aluminum electrolytic construction of the UVY1E221MED1TD makes it well suited for audio power supply reservoirs and bias decoupling, where large capacitance values above 47 µF are not economically available in ceramic form at 25 V ratings. Its 0.165 mA leakage is low enough for DC-coupled audio bias networks, and the radial 6.3 mm body is mechanically stable on audio amplifier PCBs subject to vibration.
