UHE1A471MPD

The UHE1A471MPD is a miniature, radial-lead aluminum electrolytic capacitor offering 470 µF capacitance at a 10 V rating. It is part of Nichicon's UHE series, designed for low impedance and long-term reliability in space-constrained electronic designs.

Key attributes include a compact φ8 × 11.5 mm can, rated operation from −40 °C to 105 °C, and a demonstrated endurance of 6000 hours at 105 °C, making it suitable for general-purpose power conditioning and energy-storage roles in compact systems.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a rated voltage of 10 V and a capacitance tolerance of −20% to +20%.
• Low Impedance Performance — Rated impedance 520 mΩ, supporting improved ripple handling and transient response in power circuits.
• Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.19 (measured at 20 °C, 120 Hz, 10 V), providing a quantifiable dissipation factor for design evaluation.
• Ripple Current Capability — Low-frequency ripple current 480 mA at 120 Hz and high-frequency ripple current 640 mA at 10 kHz, enabling reliable AC ripple handling across common operating frequencies.
• Leakage Current — Specified leakage current of 47 µA (measured after rated voltage application), useful for estimating standby and bias losses.
• Long Endurance — Designed for 6000 hours of endurance at 105 °C (for φD = 8, 10 and 6.3–10 V rating range), maintaining capacitance, tan δ and leakage within defined limits after the endurance test.
• Mechanical Profile — Compact radial can: φ8 × 11.5 mm (L: 1.15 × D: 0.8 cm) with 3.5 mm lead spacing (±0.5 mm), suitable for through-hole PCB layouts where small footprint is required.
• Packaging & Compliance — Available in bulk or bag packing (no terminal forming) and compliant with RoHS directive.

Typical Applications

• General-purpose power filtering — Compact 470 µF/10 V radial capacitor for smoothing and filtering in small power supplies and peripheral power rails.
• Decoupling for regulators — Low impedance and defined ripple current ratings support decoupling and stability for point-of-load regulators and DC–DC converters in space-limited designs.
• Consumer and industrial electronics — Small form factor and long endurance at elevated temperature make it suitable for a range of compact consumer and industrial devices requiring reliable energy storage.

Unique Advantages

• Compact, space-saving package — φ8 × 11.5 mm can and short radial profile reduce board area while delivering 470 µF capacitance.
• Quantified low impedance — 520 mΩ impedance specification provides a measurable basis for thermal and ripple-performance calculations.
• Broad ripple capability — Specified ripple currents at both 120 Hz and 10 kHz allow confident selection across low- and high-frequency applications.
• Long operational life at elevated temperature — 6000 hours at 105 °C supports designs that require sustained performance under thermal stress.
• Wide operating temperature range — Rated from −40 °C to 105 °C to accommodate a broad set of environmental conditions.
• RoHS compliance and straightforward mounting — Pb-free construction and radial through-hole form factor simplify assembly and regulatory compliance planning.
