UHW1V471MPD

The UHW1V471MPD is a miniature, high‑reliability aluminum electrolytic capacitor in a radial lead can from Nichicon’s UHW series. It provides 470 µF capacitance at a 35 V rating with polarized radial leads, designed for general‑purpose power and decoupling uses in compact electronic assemblies.

Engineered for demanding operating conditions, the UHW1V471MPD combines low impedance, high ripple current capability and a wide temperature range (−40°C to 105°C) for reliable performance in industrial and commercial electronics.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance, suitable for bulk filtering and energy storage in DC power rails.
• Low Impedance — Specified impedance of 90 mΩ, enabling effective smoothing and reduced voltage ripple in power supply circuits.
• High Ripple Current — Low‑frequency ripple current rating of 1.0 A (120 Hz) and high‑frequency ripple current rating of 2.0 A (10 kHz), supporting higher AC stress and improved thermal performance.
• Temperature & Endurance — Operating range −40°C to 105°C with an endurance rating of 10,000 hours at 105°C, providing long‑term stability under elevated temperature and bias conditions.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.11 measured at 20°C, 120 Hz, for predictable ESR and dissipation behavior.
• Compact Radial Package — φ10 × 16 mm can with 5 mm lead spacing (±0.5 mm), radial lead mounting for through‑hole PCB assemblies and easy hand or wave insertion; available in bulk or bag packing.
• Leakage Current — Specified leakage current of 164.5 µA, useful for designing bias and holding circuits with known standby draw.
• RoHS Compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• Power Supply Filtering — Bulk and output smoothing for DC power rails where 470 µF at 35 V removes low‑frequency ripple and stabilizes regulator outputs.
• DC/DC Converters — Input/output decoupling where low impedance and high ripple current handling improve converter stability and thermal margin.
• Industrial Control Electronics — Energy buffering and transient suppression in compact control boards operating across −40°C to 105°C.
• Consumer and Commercial Equipment — General‑purpose energy storage and filtering in compact through‑hole assemblies requiring reliable, long‑life capacitors.

Unique Advantages

• Compact, High‑Capacity Package: 470 µF in a φ10 × 16 mm can saves PCB area while delivering useful bulk capacitance for space‑constrained designs.
• High Ripple Current Capability: 1.0 A @120 Hz and 2.0 A @10 kHz reduce heating and extend service life under AC stress compared with lower‑rated units.
• Proven Endurance: 10,000 hours at 105°C provides designers a defined lifetime metric for thermal budgeting and long‑term reliability planning.
• Predictable Electrical Losses: tan δ of 0.11 at 20°C/120 Hz and 90 mΩ impedance give clear parameters for ESR‑related design calculations.
• Through‑Hole Flexibility: Radial lead format with 5 mm spacing simplifies prototyping and replacement in existing through‑hole assemblies.
• RoHS Compliance and Production Availability: Environmentally compliant and in mass production for reliable supply in production programs.
