UHW1E471MPD

The UHW1E471MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UHW series. It is a radial lead, polarized capacitor specified at 470 µF and 25 V, designed for general-purpose electronic applications.

Key value comes from its combination of high ripple-current capability and low impedance in a compact φ10 × 12.5 mm can, along with long endurance at elevated temperature (10000 h at 105°C), making it suitable where sustained AC stress and space-efficient packaging are required.

Key Features

• Capacitance & Rated Voltage — 470 µF capacitance with a rated voltage of 25 V and tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Miniature Radial Can — φ10 × 12.5 mm package with radial leads and 5.0 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing.
• High Ripple Current — Low-frequency ripple current of 850 mA (120 Hz) and high-frequency ripple current of 1.7 A (100 kHz), supporting AC stress across a broad frequency range.
• Low Impedance — Specified impedance of 150 mΩ and documented series characteristic of lower impedance at high frequencies.
• Endurance & Temperature Range — Rated for operation from -40°C to +105°C with a rated lifetime of 10000 hours at 105°C under specified endurance conditions.
• Loss Tangent (tan δ) — tan δ specified at 0.13 (measured at 20°C, 120 Hz) for stable dissipation characteristics.
• Leakage Current — Specified leakage current of 117.5 µA (measurement condition per product data).
• Regulatory — RoHS compliant as part of Nichicon's UHW series.

Typical Applications

• Power supply filtering — Bulk and smoothing applications where 470 µF capacitance and high ripple current capability reduce voltage ripple under AC stress.
• DC–DC converter outputs — Output stage decoupling requiring compact high-capacitance components with low impedance at switching frequencies.
• Embedded and general-purpose electronics — Space-constrained assemblies that require a durable polarized capacitor with a wide operating temperature range (-40°C to 105°C).
• High-frequency ripple handling — Circuits experiencing significant high-frequency ripple benefit from the UHW series’ lower impedance at elevated frequencies and specified high-frequency ripple current.

Unique Advantages

• High ripple-current tolerance — 1.7 A at 100 kHz and 850 mA at 120 Hz provide headroom for AC-stressed applications.
• Compact form factor — φ10 × 12.5 mm radial can delivers 470 µF in a small footprint for space-sensitive designs.
• Designed for sustained elevated-temperature operation — 10000 hours endurance at 105°C supports long-term reliability under continuous operating conditions.
• Low measured impedance (150 mΩ) — Improves AC performance and helps maintain stable circuit operation across frequencies.
• Manufacturing-friendly radial leads — Standard 5.0 mm lead spacing (±0.5 mm) for through-hole mounting and straightforward mechanical integration.
• RoHS compliant — Meets RoHS directive requirements for restricted substances.
