UTH2G121MND6

The UTH2G121MND6 is a miniature, high-voltage aluminum electrolytic capacitor from Nichicon’s UTH series, designed for general-purpose applications that require compact size and long life. It combines a 120 µF capacitance with a 400 V rating in a radial‑lead can package, offering a balance of voltage handling and miniature footprint.

Engineered for extended operation, this part supports operation across −40 °C to +105 °C and carries a specified endurance of 5000 hours at 105 °C, making it suitable for designs that need sustained performance at elevated temperatures.

Key Features

• High Voltage / Capacitance: 120 µF rated capacitance at 400 V provides energy storage for high-voltage circuits needing a compact capacitor solution.
• Miniature Radial Can Package: Radial, can-style package with radial lead mounting and 7.5 mm lead spacing in a compact 18 × 26 mm (L × D) case (listed size L: 2.6 × D: 1.8 cm).
• Long Life Endurance: Rated endurance of 5000 hours at 105 °C under D.C. bias plus rated ripple current, with capacitance change within ±20% after the test.
• Wide Operating Temperature: Specified temperature range from −40 °C to +105 °C for reliable operation across typical environmental conditions.
• Ripple Current Capability: Rated ripple current of 755 mA at 120 Hz (105 °C); frequency-dependent capability increases to 1.208 A at 10 kHz.
• Leakage Current Specification: Leakage current limits defined as after 1 minute ≤ 0.04CV + 100 µA and after 5 minutes ≤ 0.02CV + 25 µA (measured at 20 °C), enabling predictable leakage behavior.
• Loss Characteristics: Maximum tan δ of 0.20 (measured at 120 Hz, 20 °C) to characterize dissipation under normal conditions.

Typical Applications

• General-purpose power electronics: Suitable where a compact, 400 V capacitor is required and extended high-temperature endurance is a priority.
• Industrial equipment: Fits designs that require a miniature radial-lead high-voltage capacitor with defined ripple current capability at 105 °C.
• Consumer and commercial electronics: Applicable to assemblies that call for a reliable, long-life aluminum electrolytic capacitor in a small can package.

Unique Advantages

• High-voltage capability in a small footprint: 400 V rating with 120 µF capacitance in an 18 × 26 mm case delivers space savings without sacrificing voltage performance.
• Designed for prolonged elevated-temperature operation: 5000-hour endurance at 105 °C supports long-term deployment in thermally demanding environments.
• Predictable ripple handling: Specified ripple current at 120 Hz and a documented frequency coefficient (yielding 1.208 A at 10 kHz) helps designers size capacitors to real-world switching and ripple conditions.
• Measured leakage behavior: Clear leakage current formulas (0.04CV+100 µA after 1 minute; 0.02CV+25 µA after 5 minutes at 20 °C) enable accurate margining in low-current designs.
• Stable dissipation characteristics: tan δ capped at 0.20 (120 Hz, 20 °C) aids in thermal and loss budgeting for power designs.
