UBT2C151MHD8

The UBT2C151MHD8 is a radial-lead aluminum electrolytic capacitor from Nichicon’s UBT series designed for demanding high-temperature applications. It delivers 150 µF capacitance at a 160 V rating with polarity, compact φ16 × 30.5 mm dimensions, and a rated operating temperature range of −40°C to +125°C.

Engineered for automotive and other high-reliability power electronics, this part combines AEC-Q200 qualification, extended life performance (2000 hours at 125°C), and measurable ripple-handling characteristics to support robust power filtering and energy-storage needs in thermally stressed environments.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a 160 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High-Temperature Endurance — Rated for continuous operation from −40°C to +125°C with an endurance rating of 2000 hours at 125°C.
• AEC-Q200 Qualified — Built to meet AEC-Q200 requirements for component-level reliability in automotive electronic designs.
• Ripple Current Performance — Low-frequency ripple current of 434 mA (120 Hz) and high-frequency ripple current of 651 mA (100 kHz) to support filtering under varying load conditions.
• Leakage and Loss Characteristics — Specified leakage current of 1060 µA and tanδ (loss tangent) of 0.20 measured at 20°C, 120 Hz.
• Radial Can Package — φ16 × 30.5 mm aluminum can with 7.5 mm lead spacing (±0.5 mm) in radial lead form factor; available in bulk (no terminal forming) or bag packing.
• RoHS Compliant — Meets RoHS requirements for environmental compliance.

Typical Applications

• Automotive electronic power systems — Provides 150 µF at 160 V with high-temperature endurance and AEC-Q200 qualification for use in vehicle power electronics where thermal and reliability demands are high.
• Power supply decoupling and smoothing — Suitable where defined ripple current handling (434 mA @120 Hz, 651 mA @100 kHz) and low-frequency stability are required.
• High-temperature energy storage — Use in designs requiring stable capacitance and leakage behavior across −40°C to +125°C operating range and specified life at elevated temperature.

Unique Advantages

• High-temperature capability: Specified −40°C to +125°C operation and 2000 hours endurance at 125°C support deployment in thermally stressed environments.
• Automotive-grade reliability: AEC-Q200 qualification provides verifiable component-level reliability for automotive electronics.
• Defined ripple handling: Separate low- and high-frequency ripple current ratings allow designers to evaluate performance across a range of switching and line-frequency conditions.
• Compact radial form factor: φ16 × 30.5 mm can with 7.5 mm lead spacing offers a space-efficient solution for through-hole power assemblies.
• Clear electrical characteristics: Specified tanδ and leakage current values measured at standard conditions (20°C, 120 Hz) simplify design margin calculations.
• Packaging flexibility: Available in bulk (no terminal forming) or bag packing to suit assembly and stocking preferences.
