Key Features
- 220 µF capacitance at 100 V rating in a 16 mm diameter radial through-hole can for compact PCB-level power supply filtering and energy hold-up
- Through-hole radial mounting enabling wave-solder or hand-solder assembly in power converter output stages and industrial control boards
- RoHS-compliant aluminum wet electrolytic construction with 0.66 mA max leakage current supporting long-term reliability in industrial power circuits
Applications
The UPW2A221MHD is used as output filter and energy storage capacitance in offline power supplies, 48 V to 100 V DC/DC converters, and industrial motor drive input stages where through-hole assembly is preferred. Its 220 µF at 100 V rating suits hold-up buffering in PLC power supplies and post-rectifier filtering in equipment that must retain regulated output for 10 ms to 20 ms during brief line interruptions.

Frequently Asked Questions
What capacitance and voltage rating does the UPW2A221MHD offer for industrial power supply filtering?
The UPW2A221MHD is rated at 220 µF and 100 V, providing meaningful energy storage equal to ½ × 220 µF × (100 V)² = 1.1 J. In an offline power supply with an 85 V DC bus, this capacitance holds up output voltage for approximately 10 ms to 20 ms depending on load current, meeting the hold-up time requirements of many industrial control systems and PLC power supply specifications.
Can the UPW2A221MHD be used in a 48 V telecom rectifier, and does derating the voltage improve reliability?
Yes, the 100 V rated UPW2A221MHD can be applied in a 48 V rectifier application, providing a 2× voltage derating margin. Capacitor manufacturers including Nichicon typically show Arrhenius lifetime models where halving the applied voltage relative to the rated voltage can more than double the expected service life at a given operating temperature, making the 100 V part at 48 V bus a longer-lived alternative to a 63 V rated capacitor running near its voltage limit.
What mounting style does the UPW2A221MHD use, and what is the body diameter for PCB layout planning?
The UPW2A221MHD uses through-hole radial lead mounting with a 16 mm body diameter and a standard lead pitch of 7.5 mm. This physical format is compatible with wave-solder and selective-solder assembly processes used in industrial power supply manufacturing, and the 16 mm diameter requires a 17 mm to 18 mm PCB pad clearance zone to accommodate the body with tolerance for component placement offsets.
