UHE1A472MHD

The UHE1A472MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UHE series, offering a high 4700 µF capacitance at a 10 V rating. It combines compact radial can packaging (φ12.5 × 35.5 mm) with low impedance and long endurance for general-purpose electronic designs.

Designed for applications requiring significant bulk capacitance and reliable operation across a wide temperature range, this capacitor delivers defined ripple-handling capability, controlled dissipation factor, and predictable leakage for robust low-voltage power systems.

Key Features

• High Capacitance — 4700 µF nominal capacitance with ±20% tolerance, providing substantial bulk energy storage for low-voltage rails.
• 10 V Rated Voltage — Suited for 10 V nominal circuits where polarized electrolytic capacitance is required.
• Low Impedance — Specified impedance of 65 mΩ to support stable voltage behavior under load.
• Ripple Current Capability — Rated low-frequency ripple current of 2.304 A at 120 Hz and high-frequency ripple current of 2.88 A at 10 kHz to handle dynamic current demands.
• Controlled Dissipation Factor — tanδ (DF) of 0.25 measured at 20°C, 120 Hz, 10 V for predictable AC loss characteristics.
• Long Endurance — 8000 hours endurance at 105°C (per series specifications for φD ≥ 12.5 at 6.3–10 V), supporting extended operational life in elevated-temperature environments.
• Compact Radial Can — Radial lead, can-style package with 5 mm lead spacing (±0.5 mm) and overall dimensions φ12.5 × 35.5 mm for ease of through-hole mounting.
• Leakage Current — Specified leakage current of 470 µA for predictable quiescent behavior.
• RoHS Compliant — Meets RoHS requirements for materials compliance.
• Availability & Packaging — Mass production status with bulk (no terminal forming) and bag packing options for procurement flexibility.

Typical Applications

• General-purpose power filtering — Bulk smoothing and reservoir capacitance on low-voltage DC rails where 4700 µF and a 10 V rating are required.
• Power-supply decoupling — Handling ripple currents up to 2.304 A (120 Hz) and 2.88 A (10 kHz) to support stable supply voltages in electronic modules.
• Energy storage for low-voltage circuits — Local energy buffering where compact radial can form factor and predictable leakage are needed.

Unique Advantages

• High-capacitance in a compact footprint: 4700 µF in a φ12.5 × 35.5 mm package minimizes board space while providing significant stored charge.
• Measured low impedance: 65 mΩ specified impedance supports better voltage stability under load transients.
• Defined ripple handling: Clear low- and high-frequency ripple current ratings allow designers to size capacitors against expected AC stress.
• Extended high-temperature life: 8000 hours at 105°C for this case size and voltage range supports longer service life in warm operating environments.
• Predictable AC loss and leakage: Specified tanδ and leakage current values enable accurate thermal and leakage budgeting in designs.
• Production-ready packaging: Bulk and bag packing options and mass-production status simplify procurement and assembly planning.
