UHW1K471MHD6

The UHW1K471MHD6 is a Nichicon UHW series aluminum electrolytic capacitor designed for radial-lead, general-purpose power applications. It combines a compact can-style package with high ripple-current capability and specified long-term endurance for demanding thermal environments.

Key characteristics include 470 µF capacitance at 80 V, low impedance and loss (150 mΩ impedance, tanδ 0.09), a rated operating range of −40°C to +105°C, and a 12,000-hour life rating at 105°C—making it suitable where sustained high-ripple performance and reliability are required.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance for bulk energy storage and filtering.
• Low Loss and Impedance — Specified impedance of 150 mΩ and tanδ of 0.09 help reduce AC losses and improve filtering performance.
• High Ripple Current — Rated ripple current of 975 mA at 120 Hz and 1.95 A at 10 kHz supports demanding AC ripple conditions.
• Long Endurance — 12,000 hours life rating at 105°C under specified test conditions for extended operational reliability.
• Compact Radial Can Package — φ16 × 20 mm package with 7.5 mm lead spacing and radial lead mounting for through-hole assembly in space-constrained designs.
• Wide Operating Temperature — Usable from −40°C to +105°C to accommodate a broad range of environmental conditions.
• Leakage Current — Specified leakage current of 376 µA after rated voltage application.
• RoHS Compliant — Conforms to RoHS requirements as stated in product data.

Typical Applications

• General-Purpose Power Filtering — Bulk capacitance for smoothing and energy storage in general-purpose power supplies and regulators.
• High-Ripple Power Circuits — Useful in circuits where reduced impedance and elevated ripple-current handling are required.
• Industrial Electronics — Suitable for industrial control and power electronics that require prolonged operation at elevated temperatures.

Unique Advantages

• Compact footprint for space-constrained designs: φ16 × 20 mm radial can with 7.5 mm lead spacing minimizes board area while providing significant capacitance.
