UVY2G470MHD

The UVY2G470MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UVY series designed for general-purpose power applications. It provides 47 µF capacitance at a 400 V rating with polarized radial can packaging and a compact φ16 × 25 mm footprint.

Engineered for continuous operation up to 105°C with a 2000-hour endurance rating, this part targets applications that require high-voltage bulk capacitance, reliable ripple handling, and RoHS-compliant materials.

Key Features

• Capacitance & Tolerance — 47 µF nominal with a tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• High DC Voltage — Rated for 400 V operation to support higher-voltage DC link and power-supply duties.
• Temperature Range & Endurance — Rated for −40°C to 105°C operating temperature with 2000 hours endurance at 105°C under rated voltage.
• Loss Characteristics — Tangent of loss angle (tanδ) 0.25 measured at 20°C, 120 Hz, suitable for evaluating dielectric losses in power applications.
• Ripple Current Performance — Low-frequency ripple current 200 mA at 120 Hz and high-frequency ripple current 320 mA at 10 kHz for smoothing and filtering across frequencies.
• Leakage Current — Specified leakage current 852 µA for predictable standby and no-load behavior after voltage application.
• Package & Mounting — Radial lead can (φ16 × 25L) with 7.5 mm lead spacing and bulk/bag packing options for manual and automated assembly flow.
• RoHS Compliant & Pb-free Construction — Complies with RoHS requirements and uses Pb-free leadwire and PET sleeve materials (HD configuration for φD 12.5–18 mm).

Typical Applications

• General-purpose power filtering — Bulk capacitance and ripple current capability make it suitable for smoothing and decoupling in power-supply circuits.
• High-voltage DC link — 400 V rating supports DC link and energy-storage roles in medium-voltage power assemblies.
• Industrial electronics — Durable operation to 105°C and 2000-hour endurance for long-life industrial power modules and control equipment.

Unique Advantages

• High-voltage capability: 400 V rated voltage enables use in higher-voltage power rails without series stacking.
• Compact radial can: φ16 × 25 mm footprint provides a smaller case size within the UVY family, helping save board area.
• Broad temperature tolerance: −40°C to 105°C operating range supports deployment across varied environmental conditions.
• Measured ripple and leakage specs: Specified ripple current values at 120 Hz and 10 kHz and quantified leakage current (852 µA) simplify thermal and power-loss budgeting.
• RoHS and Pb-free materials: Compliant materials reduce regulatory risk and support environmentally conscious designs.
