UHW1K471MHD

The UHW1K471MHD from Nichicon is a radial lead aluminum electrolytic capacitor in the UHW series, designed for miniature size with high ripple current capability. It combines a 470 µF capacitance with an 80 V rated voltage in a compact φ12.5 × 30.5 mm can with 5 mm lead spacing.

Engineered for general-purpose electronic circuits, this capacitor targets applications that demand high-frequency performance, long endurance at elevated temperature, and RoHS-compliant components for reliable system operation.

Key Features

• Form factor and mounting: Radial lead, can-type package (φ12.5 × 30.5 mm) with 5 mm lead spacing and 0.5 mm lead spacing tolerance; available in bulk (no terminal forming) or bag packing.
• Capacitance and voltage rating: 470 µF with a capacitance tolerance of -20% to +20%, rated for 80 V DC.
• High ripple current capability: Rated low-frequency ripple current of 1.2 A at 120 Hz and high-frequency ripple current of 2.4 A at 100 kHz, supporting demanding AC ripple conditions.
• Low impedance: Specified impedance of 130 mΩ, with the UHW series noted for lower impedance at high frequency ranges.
• Thermal and lifetime performance: Operating temperature range from -40°C to +105°C and an endurance rating of 12,000 hours at 105°C.
• Electrical characteristics: Loss tangent (tan δ) of 0.09 at 120 Hz and 20°C, and a measured leakage current of 376 µA.
• Compliance: RoHS compliant; part of Nichicon’s UHW series which emphasizes miniature size, high ripple current, and high reliability.

Typical Applications

• General-purpose electronic circuits: Provides bulk capacitance and energy storage where a 470 µF, 80 V radial lead electrolytic is required.
• Power supply modules: Suited for smoothing and ripple handling in power stages that require the specified ripple current ratings and low impedance.
• Industrial and control electronics: Useful in compact designs operating across -40°C to +105°C with long endurance requirements up to 12,000 hours at the upper temperature limit.

Unique Advantages

• High ripple tolerance: Explicit ripple current ratings of 1.2 A (120 Hz) and 2.4 A (100 kHz) enable reliable performance under AC stress.
• Compact radial can: φ12.5 × 30.5 mm package provides substantial capacitance in a small footprint for space-constrained board layouts.
• Low impedance at frequency: 130 mΩ impedance and UHW series design characteristics that deliver lower impedance in high-frequency ranges.
• Extended high-temperature life: Rated for 12,000 hours at 105°C, supporting long-term operation in elevated-temperature environments.
• Measured electrical stability: tan δ of 0.09 (120 Hz, 20°C) and a defined leakage current (376 µA) for predictable circuit behavior.
• RoHS-compliant manufacture: Meets RoHS directive requirements as part of Nichicon’s UHW series production.
