UTH2G121MND

The UTH2G121MND is a Nichicon UTH series radial-lead aluminum electrolytic capacitor specified at 120 µF and 400 V. It is a general-purpose, high-voltage, miniature-sized component designed for applications requiring long-life performance in a compact can package.

Built for extended endurance, this part delivers a rated lifetime of 5000 hours at 105°C and offers measured characteristics optimized for 120 Hz testing conditions, making it suitable where sustained high-voltage capacitance is required.

Key Features

• Electrical Rating — Rated capacitance 120 µF at 120 Hz and rated voltage 400 V with capacitance tolerance of ±20%.
• Loss and Dissipation — Tangent of loss angle (tan δ) specified at 0.20 (max.) measured at 120 Hz, 20°C, providing a defined dissipation benchmark for design.
• Ripple Current Capability — Rated ripple current 790 mA (mArms) at 105°C / 120 Hz; frequency coefficient data available for scaling ripple with frequency.
• Leakage Current — Leakage current specified as 2020 µA after 1 minute and 985 µA after 5 minutes (at 20°C), enabling predictable leakage behavior in designs.
• Long-Life Endurance — Endurance rating: 5000 hours at 105°C under DC bias plus rated ripple current; capacitance change, tan δ and leakage current criteria defined by the series specification.
• Temperature Range — Operating temperature range from −40°C to +105°C for broad environmental tolerance.
• Mechanical & Mounting — Radial lead, can-style package with case size φ16 × 31.5 mm and lead spacing 7.5 mm; available in bulk (no terminal forming) or bag packing.

Typical Applications

• General Purpose Electronics — Used where a compact 400 V electrolytic capacitor is required for general-purpose circuits.
• Power Modules — Suitable for designs that require a high-voltage capacitor with defined ripple and leakage specifications.
• Industrial Equipment — Applicable in equipment requiring stable capacitance and endurance at elevated temperatures up to 105°C.

Unique Advantages

• High-voltage capability: 400 V rating supports designs that need elevated DC voltage handling in a compact footprint.
• Predictable dissipation: Specified tan δ (0.20 max. at 120 Hz, 20°C) gives clear guidance for thermal and loss calculations.
• Defined ripple performance: 790 mA rated ripple current at 105°C/120 Hz with series frequency coefficients for scaling at other frequencies simplifies ripple management.
• Long-term reliability: 5000-hour endurance at 105°C under rated conditions provides a measurable long-life metric for system lifetime planning.
• Compact, serviceable form factor: φ16 × 31.5 mm can and radial-lead mounting make the part easy to integrate into through-hole assemblies with 7.5 mm lead spacing.
• Clear leakage spec: Leakage current values after 1 and 5 minutes are specified, aiding predictable bias behavior during startup and steady state.
