UHW1E472MHD

The UHW1E472MHD from Nichicon is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can. It delivers 4.7 mF (4700 µF) capacitance at 25 V with design characteristics focused on low impedance, high ripple current capability and extended endurance.

Engineered for general-purpose power applications that require compact bulk capacitance and robust ripple performance, this radial-lead capacitor provides long-term stability across –40 °C to 105 °C and a stated endurance of 10,000 hours at 105 °C.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) nominal capacitance at a rated voltage of 25 V with tolerance −20% to +20%.
• High Ripple Current — Low-frequency ripple current of 3.4 A (120 Hz) and high-frequency ripple current of 4.0 A (10 kHz) to support demanding power-rail conditions.
• Low Impedance & Loss — Specified impedance of 33 mΩ and tangent of loss angle (tan δ) of 0.19 measured at 20 °C, 120 Hz for improved high-frequency performance.
• Long Endurance — Rated life of 10,000 hours at 105 °C under DC bias plus rated ripple current, with limits on capacitance change, tan δ increase and leakage current.
• Wide Operating Temperature — Operation across −40 °C to +105 °C for reliable behavior in varied thermal environments.
• Radial Lead Package — Compact φ16 × 30.5 mm can with 7.5 mm lead spacing (±0.5 mm) for through-hole assembly; available in bulk or bag packing.
• Leakage Current — Specified leakage current of 1175 µA (as provided), measured after rated voltage application conditions.
• RoHS Compliant — Meets RoHS requirements as stated for the UHW series.

Typical Applications

• Power supply filtering — Provides bulk capacitance and high ripple handling for smoothing DC rails in general-purpose power supplies.
• DC-DC converter outputs — Low impedance and high-frequency ripple current capability support stable output filtering in converter stages.
• Industrial electronics — Long endurance at 105 °C and wide temperature range make it suitable for demanding industrial power modules and control equipment.
• General-purpose systems — Compact radial-lead can for through-hole assemblies where robust bulk capacitance and reliability are required.

Unique Advantages

• Miniature can with high ripple capacity: φ16 × 30.5 mm package delivers 4700 µF while supporting 3.4 A–4.0 A ripple currents, helping reduce board area without sacrificing performance.
• Low impedance for improved transient response: 33 mΩ impedance and a low tan δ at 120 Hz help maintain voltage stability under dynamic load conditions.
• Extended high-temperature life: Rated for 10,000 hours at 105 °C, providing predictable aging characteristics and replacement intervals for long-running systems.
• Radial-lead form factor: Through-hole mounting with defined lead spacing simplifies assembly and mechanical retention in a range of product designs.
• Regulatory compliance: RoHS status documented for the UHW series to support environmental compliance requirements.
