UTH2G141MND

The UTH2G141MND is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UTH series. It is a radial-lead, polarized capacitor rated at 400 V with 140 µF capacitance and a ±20% tolerance, optimized for general-purpose power applications requiring compact high-voltage capacitors.

Designed for long-term operation up to 105°C, the UTH2G141MND combines a compact φ16×36 mm can with defined ripple handling, leakage, and dissipation characteristics to support dependable performance in demanding environments.

Key Features

• Capacitance & Voltage — 140 µF rated capacitance at 400 V with a tolerance of -20% to +20% for predictable energy storage in high-voltage circuits.
• Compact Radial Package — Miniature φ16×36 mm can with 7.5 mm lead spacing (±0.5 mm) and radial-lead mounting for through-hole designs; available in bulk or bag packing (no terminal forming).
• High-temperature Endurance — Rated lifetime of 5000 hours at 105°C under DC bias plus rated ripple current; after the endurance test, capacitance change is within ±20% and leakage current remains at or below the initial specified value.
• Ripple Current Capability — Rated low-frequency ripple current of 870 mA (105°C / 120 Hz) and high-frequency ripple current of 1.392 A (10 kHz), supporting AC ripple handling across frequencies.
• Controlled Losses — Tangent of loss angle (tan δ) max 0.20 at 20°C, 120 Hz (for 400 V rating), providing defined dissipation behavior for thermal and stability planning.
• Leakage Current Specification — Measured leakage current for this part is 2340 µA after 1 minute and 1145 µA after 5 minutes at 20°C, allowing precise bias/leakage budgeting in designs.
• Wide Operating Temperature — Specified for -40°C to +105°C operation, suitable for applications needing broad temperature tolerance.

Typical Applications

• General-purpose power supplies — 400 V rating and 140 µF capacitance provide energy storage and ripple filtering for medium-voltage DC bus and smoothing functions.
• Industrial power conversion — Compact φ16×36 mm package with defined ripple current ratings supports space-constrained converters and power modules where long endurance at 105°C is required.
• Energy buffering in high-voltage circuits — Polarized aluminum electrolytic construction and measurable leakage/tanδ values allow engineers to account for charge storage and dissipation in high-voltage designs.

Unique Advantages

• Miniature high-voltage form factor — φ16×36 mm can enables high-voltage capacitance in a small footprint, simplifying PCB layout for through-hole applications.
• Long-life assurance at elevated temperature — 5000-hour endurance at 105°C gives design confidence for extended field operation under temperature and ripple stress.
• Frequency-aware ripple performance — Specified low-frequency and high-frequency ripple currents (870 mA at 120 Hz, 1.392 A at 10 kHz) allow accurate thermal and ripple budgeting across operating frequencies.
• Predictable electrical loss and leakage — tan δ of 0.20 (120 Hz, 20°C) and documented leakage current values support precise system-level power-loss and standby-current calculations.
• Standardized mounting and packaging — Radial lead configuration with 7.5 mm lead spacing and bulk/bag packing options ease assembly and procurement for production runs.
