The UVK2W470MHD is a miniature radial lead aluminum electrolytic capacitor from Nichicon’s UVK series. It is a standard-type, polarized capacitor offering 47 µF capacitance at a 450 V rated voltage in a compact φ16 × 30.5 mm can.

Designed for general-purpose applications, the part delivers a combination of high-voltage capability, compact footprint, and long endurance (2000 hours at 85°C). It is RoHS compliant and supplied in bulk or bag packing for production use.

Key Features

• Capacitance & Voltage — 47 µF capacitance with a 450 V rated voltage for high-voltage circuit requirements.
• Miniature UVK Package — φ16 × 30.5 mm can size (φ16 × 30.5L) provides a compact solution; radial lead mounting with 7.5 mm lead spacing (±0.5 mm).
• Endurance — Rated for 2000 hours at 85°C with specified post-test limits: capacitance within ±20%, tan δ ≤ 200% of initial spec, and leakage current ≤ initial spec.
• Temperature Range — Operating temperature range of −25°C to +85°C for the 450 V rating.
• Electrical Loss & Leakage — Specified tan δ of 0.25 (measured at 20°C, 120 Hz) and leakage current of 946 µA as provided for this part.
• Ripple Current Ratings — Low-frequency ripple current 220 mA (120 Hz) and high-frequency ripple current 352 mA (10 kHz) for AC ripple handling.
• Polarized Radial Lead — Standard radial lead can style for through-hole mounting; packaging options include bulk (no terminal forming) and bag packing. Status: Mass Production.
• Regulatory — RoHS compliant per provided product data.

Typical Applications

• General Purpose Electronics — For circuits requiring a polarized aluminum electrolytic capacitor with 47 µF capacitance and 450 V rating in a compact radial package.
• High-Voltage, Space-Conscious Designs — Provides a 450 V rated capacitor in a miniature φ16 × 30.5 mm can where board space is limited and elevated voltage handling is required.
• Long-Life Industrial or Commercial Systems — 2000-hour endurance at 85°C supports applications that need sustained performance over extended operating periods.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage circuits without increasing capacitor footprint.
• Compact UVK form factor: Miniature case size (φ16 × 30.5 mm) delivers space savings compared with larger electrolytic types.
• Defined endurance: 2000 hours at 85°C provides predictable long-term behavior for design validation and lifecycle planning.
• Clear electrical specifications: Documented tan δ (0.25 at 20°C, 120 Hz), leakage current, and ripple current ratings support accurate thermal and reliability calculations.
• Radial lead convenience: Standard radial can and 7.5 mm lead spacing simplify through-hole placement and mechanical retention on PCBs.
• RoHS compliant and production-ready: Meets environmental compliance requirements and is available in mass-production packaging options.
