UHW1H471MPD

The UHW1H471MPD is a miniature, high‑reliability aluminum electrolytic capacitor in Nichicon's UHW series, configured in a radial‑lead can. It provides 470 µF capacitance at a 50 V rating with a compact φ10 × 25L footprint and 5 mm lead spacing.

Built for general‑purpose applications that require low impedance and high ripple handling in a small through‑hole package, the UHW1H471MPD delivers extended endurance and stable performance across a −40 °C to +105 °C operating range.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a rated voltage of 50 V and capacitance tolerance of ±20% (−20% to +20%) at 120 Hz, 20 °C.
• Low impedance — Specified impedance of 84 mΩ, supporting improved high‑frequency performance noted in the UHW series.
• High ripple current capability — Rated ripple current of 1.21 A at 120 Hz and 2.42 A at 10 kHz for handling AC components on DC rails.
• Endurance — Life rating of 10,000 hours at 105 °C under the UHW series endurance conditions.
• Thermal range — Operational from −40 °C to +105 °C for broad environmental tolerance.
• Leakage & dissipation — Leakage current specified at 235 µA and tangent of loss angle (tan δ) approximately 0.10 measured at 20 °C, 120 Hz.
• Compact radial package — φ10 × 25L can (L: 2.5 cm × D: 1.0 cm) with 5 mm lead spacing (±0.5 mm) for through‑hole mounting.
• Packaging — Available in bulk (no terminal forming) and bag packing to suit production or prototyping workflows.
• Compliance — RoHS‑compliant.

Typical Applications

• General‑purpose power filtering — Smoothing and ripple reduction on DC rails where a compact, high‑ripple‑capable electrolytic is required.
• Power supply decoupling — Board‑level decoupling in through‑hole designs that benefit from low impedance at higher frequencies.
• Energy buffering — Local energy storage on PCBs where a small footprint and polarized radial mounting are preferred.

Unique Advantages

• High ripple handling — 1.21 A (120 Hz) and 2.42 A (10 kHz) ripple ratings help maintain stability under AC stress on DC lines.
• Compact footprint — φ10 × 25L can with 5 mm lead spacing minimizes board area while offering substantial capacitance.
• Extended life at elevated temperature — Rated for 10,000 hours at 105 °C to support long‑term reliability in demanding thermal environments.
• Low impedance — 84 mΩ impedance supports improved transient and high‑frequency performance consistent with the UHW series design goals.
• Measured electrical characteristics — Specified tan δ and leakage current values allow predictable loss and standby current budgeting in designs.
• RoHS compliance — Meets RoHS directive requirements for material restrictions.
