Key Features
- 220 µF capacitance at 35 V rating delivers substantial bulk energy storage for power supply filtering applications
- 25 mm diameter radial leaded package provides through-hole PCB compatibility with a compact footprint for high-capacitance designs
- Wet aluminum electrolytic construction with non solvent-proof rating ensures long operational life in stable indoor environments
Applications
The UPW2V221MRD is used in power supply filter stages, DC-DC converter output bulk capacitance, and audio amplifier power rail decoupling. Its 220 µF at 35 V rating makes it effective for smoothing rectified AC voltage ripple in industrial and consumer power adapters. The radial leaded 25 mm body fits standard PCB through-hole footprints used across motor drives, LED drivers, and control board designs.

Frequently Asked Questions
What are the key electrical ratings of the Nichicon UPW2V221MRD and in which power supply stages does it fit?
The UPW2V221MRD is rated at 220 µF capacitance and 35 V working voltage with a maximum leakage current of 3.18 mA. These parameters make it well suited for output bulk filtering in 24 V or 28 V DC power supplies, post-rectifier smoothing stages, and hold-up capacitor banks in industrial power adapters operating up to 35 V.
How does the 25 mm diameter body of the UPW2V221MRD affect PCB layout compared to smaller 220 µF alternatives?
At 25 mm diameter the UPW2V221MRD occupies a larger PCB footprint than compact 12.5 mm or 16 mm body alternatives at the same 220 µF / 35 V rating. Designers should verify a minimum 26 mm clearance hole and lead spacing of 10 mm or 12.5 mm on the PCB. The larger body typically offers lower ESR and higher ripple current capability than miniaturized equivalents.
Is the Nichicon UPW2V221MRD RoHS-compliant and suitable for lead-free soldering processes?
The UPW2V221MRD carries a Pbfree code indicating lead-free terminal plating compatible with lead-free reflow and wave soldering at temperatures up to 260°C for 10 seconds. However, its REACH compliance code is listed as Not Compliant, so designers targeting full REACH-compliant BOM selection should verify substance declarations before use in regulated product categories.
