UTH2G151MND

The UTH2G151MND from Nichicon is a miniature, high‑voltage aluminum electrolytic capacitor in a radial lead can (UTH series). It delivers 150 µF capacitance at a 400 V rating with a compact φ18×31.5 mm package and 7.5 mm lead spacing, designed for general‑purpose high‑voltage power applications that require long life and stable performance.

Key value comes from its long endurance (5000 hours at 105°C under rated DC bias plus ripple), industry‑relevant ripple handling, and controlled leakage and dissipation characteristics — making it suitable for applications that demand reliable bulk filtering and energy smoothing at elevated voltages and temperatures.

Key Features

• High Voltage Rating — 400 V rated voltage for high‑voltage power designs and bulk energy filtering.
• Nominal Capacitance — 150 µF with ±20% tolerance (measured at 120 Hz, 20°C) for predictable charge storage and decoupling.
• Compact Radial Can — φ18×31.5 mm case with 7.5 mm lead spacing and radial lead mounting for through‑hole assembly and robust mechanical retention.
• Long Endurance — 5000 hours at 105°C under DC bias plus rated ripple current; capacitance change within ±20% and leakage current remains at or below initial specified values after endurance.
• Ripple Current Capability — 915 mA at 120 Hz (low frequency) and 1.464 A at 10 kHz (high frequency), enabling effective smoothing across a wide ripple spectrum. Use the frequency coefficients (50 Hz: 0.80, 120 Hz: 1.00, 300 Hz: 1.25, 1 kHz: 1.40, 10 kHz+: 1.60) to scale ripple ratings for other frequencies.
• Controlled Loss and Leakage — tan δ ≤ 0.20 (120 Hz, 20°C) for stable dissipation; leakage current for this part is specified as 2500 µA after 1 minute and 1225 µA after 5 minutes at 20°C. Leakage limits also follow the datasheet formulas: after 1 minute not more than 0.04CV+100 µA and after 5 minutes not more than 0.02CV+25 µA.
• Wide Operating Temperature — −40°C to +105°C operating range for use in elevated temperature environments within the endurance specification.
• Polarized, General‑Purpose — polarized aluminum electrolytic optimized for general‑purpose power circuits and bulk capacitance roles.
• Packaging — available in bulk (no terminal forming) and bag packing for flexible procurement and assembly handling.

Typical Applications

• High‑Voltage Power Supplies — bulk filtering and energy smoothing where a 400 V rating and 150 µF capacitance are required for stable DC rails.
• Industrial Power Conversion — input/output smoothing in converters and controllers that operate at elevated temperatures and require extended lifetime (5000 h at 105°C).
• Energy Storage and Filtering — bulk decoupling for systems needing high ripple handling across low and high frequencies, using the provided ripple ratings and frequency coefficients to size correctly.

Unique Advantages

• High‑Voltage Capability: 400 V rating enables use in higher‑voltage power systems without stepping up to larger form factors.
• Long‑Life Assurance: 5000‑hour endurance at 105°C under rated bias and ripple ensures predictable ageing characteristics for design longevity.
• Predictable Electrical Behavior: Specified tan δ (≤0.20) and explicit leakage current values and formulas allow accurate thermal and leakage budgeting in designs.
• Broad Ripple Performance: Distinct low‑ and high‑frequency ripple current specs plus frequency coefficients simplify ripple‑current derating across common switching frequencies.
• Compact Footprint: φ18×31.5 mm can with radial lead configuration offers a balance of capacitance and board space for through‑hole assemblies.
• Practical Packaging Options: Bulk and bag packing options support different manufacturing workflows and inventory strategies.
