UTH2W470MND

The UTH2W470MND is a miniature, high-voltage aluminum electrolytic capacitor from Nichicon’s UTH series. It is a radial-lead, polarized capacitor with a rated capacitance of 47 µF and a rated voltage of 450 V, designed for general-purpose high-voltage circuit requirements.

This part combines compact dimensions (φ16 × 20 mm), long-life assurance (5,000 hours at 105°C), and measurable performance characteristics—making it suited where a reliable, compact 450 V electrolytic solution is required.

Key Features

• Electrical Performance — Rated capacitance 47 µF with tolerance ±20% (measured at 120 Hz, 20°C); tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, 20°C.
• High Voltage — Rated for 450 V operation, providing a compact option for high-voltage circuits within the UTH series specification range.
• Ripple Current Capability — Low-frequency ripple current 430 mA at 120 Hz and high-frequency ripple current 688 mA at 10 kHz, specified at 105°C.
• Leakage Current — Specified leakage current 946 µA (as provided for this part), measured under standard conditions.
• Long-Life Reliability — Endurance rating of 5,000 hours at 105°C with specified limits for capacitance change, tan δ, and leakage current after the test.
• Compact Radial Package — Miniature radial-can construction (φ16 × 20 mm) with 7.5 mm lead spacing (±0.5 mm), available in bulk or bag packing.
• Wide Operating Temperature Range — Specified for −40°C to +105°C operation.

Typical Applications

• General-purpose high-voltage circuits — Suitable where a 47 µF, 450 V aluminum electrolytic capacitor in a compact radial package is required.
• High-temperature environments — Applicable for designs that require operation across −40°C to +105°C and endurance at elevated temperature (5,000 hours at 105°C).
• Compact assemblies with radial leads — Designed for use in layouts that accept a φ16 × 20 mm radial can with 7.5 mm lead spacing.

Unique Advantages

• High-voltage capability: 450 V rating provides headroom for high-voltage circuits while maintaining a compact footprint.
• Measured loss and leakage specs: tan δ ≤ 0.20 (120 Hz, 20°C) and specified leakage current provide predictable AC and DC performance for design verification.
• Effective ripple handling: Specified ripple currents at both low (430 mA at 120 Hz) and high frequencies (688 mA at 10 kHz) allow assessment of performance across common ripple spectra.
• Long-term endurance: 5,000 hours at 105°C supports reliability planning for sustained high-temperature operation.
• Miniature radial form factor: φ16 × 20 mm can size with 7.5 mm lead spacing minimizes PCB area while providing thru-hole mounting convenience.
• Packaging options: Available in bulk (no terminal forming) or bag packing to suit assembly and inventory preferences.
