UHD1A472MHD

The UHD1A472MHD is a radial-lead aluminum electrolytic capacitor with a rated capacitance of 4700 µF (4.7 mF) and a nominal voltage of 10 V. It is part of Nichicon’s UHD series, designed for general-purpose electronic circuits that require high ripple handling and low impedance across a wide frequency range.

Its compact φ12.5 × 35.5 mm can and radial-lead format offer a balance of high capacitance in a small footprint, while endurance and temperature specifications support extended operation in demanding environments.

Key Features

• Capacitance and Voltage — 4700 µF (4.7 mF) nominal capacitance with a rated voltage of 10 V and ±20% tolerance, suitable where high bulk capacitance at low voltage is required.
• High Ripple Current — Low-frequency ripple current of 2.72 A (at 120 Hz) and high-frequency ripple current of 3.4 A (at 100 kHz) to support applications with substantial AC ripple components.
• Low Leakage — Specified leakage current of 470 µA (measured per product data), reducing standby losses in DC circuits.
• Wide Temperature Range — Rated for operation from –40 °C to +105 °C, with endurance specified for 5000 hours at 105 °C.
• Low Impedance Design — UHD series characteristics include lower impedance at high frequency, enabling improved performance in circuits sensitive to ESR/impedance.
• Radial Lead, Compact Case — φ12.5 × 35.5 mm can with 5 mm lead spacing (±0.5 mm tolerance) and radial-lead mounting for through-hole assembly and manual or automated placement.
• Packaging Options — Available in bulk (no terminal forming) and bag packing to suit different assembly workflows.
• RoHS Compliant — Conforms to RoHS directives as stated in the product data.

Typical Applications

• General-purpose electronic circuits — Bulk energy storage and smoothing where a 4700 µF, 10 V capacitor is required.
• Power filtering in low-voltage systems — Use where high ripple current capability and low impedance at frequency are important.
• Through-hole assemblies — Radial-lead format for PCB-mounted, general-purpose designs using bulk-pack or bag-pack components.

Unique Advantages

• High ripple handling: Rated ripple currents of 2.72 A (120 Hz) and 3.4 A (100 kHz) provide headroom for circuits with substantial AC components, improving reliability under ripple stress.
• Extended endurance at elevated temperature: 5000 hours life at 105 °C supports sustained operation in warm environments and long-life applications.
• Compact, high-capacitance profile: 4700 µF in a φ12.5 × 35.5 mm can saves board space compared with larger cases for similar capacitance values.
• Low leakage: Leakage current specified at 470 µA helps reduce no-load losses in DC systems.
• Low impedance at high frequency: UHD series design lowers impedance in the high-frequency range, benefiting decoupling and filtering performance.
• RoHS compliance and packaging flexibility: Environmentally compliant and available in bulk or bag packing to match assembly processes.
