UCY2G151MHD

The UCY2G151MHD is a miniature, radial-lead aluminum electrolytic capacitor in Nichicon’s UCY series designed for high ripple-current and long-life applications. It delivers 150 µF capacitance at a 400 V rating in a compact φ18 × 40 mm can with 7.5 mm lead spacing.

Targeted at power-dense environments, this high-reliability capacitor supports sustained operation up to 105°C and is suited for automotive electronics and demanding power-supply or ballast use cases where high ripple handling and endurance are required.

Key Features

• Electrical Performance — 150 µF capacitance with ±20% tolerance and a rated voltage of 400 V; tangent of loss angle (tanδ) 0.24 measured at 20°C, 120 Hz.
• High Ripple Capability — Low-frequency ripple current 1.03 A at 120 Hz and high-frequency ripple current 2.06 A at 100 kHz, enabling use in high-ripple power circuits.
• Long Endurance — Rated life of 12,000 hours at 105°C under DC bias plus rated ripple current, supporting extended duty in elevated-temperature environments.
• Thermal Range — Operating temperature range –40°C to +105°C for robustness across a wide range of operating conditions.
• Mechanical / Mounting — Radial lead can package (φ18 × 40 mm) with 7.5 mm lead spacing (±0.5 mm); available in bulk or bag packing.
• Leakage & Reliability — Specified leakage current up to 2500 µA and compliance with RoHS; the series also carries AEC-Q200 qualification.

Typical Applications

• Automotive Electronics — Suitable for vehicle power systems and modules that require capacitors qualified to AEC-Q200 and rated for sustained high-temperature operation.
• Power Supplies & Ballasts — Designed for use in power-supply filter stages and ballast circuits where high ripple current capability and long life at 105°C are important.
• High-Ripple, High-Temperature Power Circuits — Ideal for densely packed power electronics that demand compact components able to handle significant ripple at elevated temperatures.

Unique Advantages

• High Voltage Handling: 400 V rating provides headroom for mid- to high-voltage power designs.
• Strong Ripple Performance: Specified ripple currents of 1.03 A (120 Hz) and 2.06 A (100 kHz) allow reliable filtering in both low- and high-frequency environments.
• Extended High-Temperature Life: 12,000-hour endurance at 105°C supports long-term reliability in thermal-stressed applications.
• Automotive-Grade Qualification: AEC-Q200 listing supports use in automotive electronic designs that require industry-recognized reliability screening.
• Compact Radial Can: φ18 × 40 mm form factor with 7.5 mm lead spacing balances board-space economy with robust mechanical mounting.
• Regulatory Compliance: RoHS-compliant construction reduces regulatory risk for commercial and automotive programs.
