UHD0J472MHD

The UHD0J472MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UHD series. It is a radial-lead, polarized capacitor rated at 4.7 mF (4700 µF) and 6.3 V, designed for general-purpose power filtering and energy storage in compact assemblies.

As part of the UHD “High Ripple Low Impedance” family, this part combines a compact φ12.5 × 30.5 mm can with elevated ripple-current capability and lower impedance at high frequencies, delivering extended endurance in demanding thermal environments.

Key Features

• Capacitance & Tolerance — 4700 µF nominal capacitance with a tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 6.3 V working voltage suitable for low-voltage power rails.
• High Ripple Current — Low-frequency ripple current of 2.632 A at 120 Hz and high-frequency ripple current of 3.29 A at 100 kHz, supporting high-current smoothing applications.
• Low Dissipation Factor — tanδ = 0.28 measured at 20°C, 120 Hz for controlled dissipation in AC conditions.
• Leakage Current — Specified leakage current of 296.1 µA (measured after standard conditioning).
• Extended Endurance — 5000 hours life at 105°C for long-term reliability under elevated temperature operation.
• Operating Temperature Range — −40°C to +105°C to cover a wide range of environmental conditions.
• Compact Radial Package — φ12.5 × 30.5 mm can with 5 mm lead spacing (±0.5 mm), available in bulk or bag packing; radial lead mounting for through-hole assembly.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling on low-voltage power rails where high capacitance and ripple handling are required.
• Switching power supplies — Input/output filtering and energy reservoir for converters that demand high ripple-current capability and low impedance at higher frequencies.
• Industrial and consumer electronics — General-purpose bulk capacitance in compact assemblies requiring extended endurance at elevated temperatures.

Unique Advantages

• High ripple-handling capacity: Rated ripple currents of 2.632 A (120 Hz) and 3.29 A (100 kHz) support demanding smoothing and filtering tasks.
• Large capacitance in a small can: 4700 µF packed into a φ12.5 × 30.5 mm package reduces board area compared with larger-diameter options.
• Long endurance at elevated temperature: 5000 hours at 105°C provides predictable lifetime performance in hot operating environments.
• Low impedance at high frequency: UHD series design focus on reduced impedance across high frequencies helps maintain stable rail performance under dynamic loads.
• Through-hole radial form factor: Easy integration into through-hole assemblies with 5 mm lead spacing and standard radial mounting.
• Regulatory compliance: RoHS compliance supports environmentally constrained designs and procurement.
