UCZ1K151MNS1MS

The UCZ1K151MNS1MS is a surface-mount aluminum electrolytic capacitor in Nichicon’s UCZ series designed for high-temperature, high-reliability applications. It delivers 150 µF capacitance at an 80 V rating in a compact radial can SMD package (φ12.5 × 13.5L) suitable for automated assembly with embossed carrier taping.

With an operating temperature range of -40 °C to 125 °C and AEC-Q200 qualification, this part targets demanding environments where temperature endurance, low ESR, and controlled loss angle are required.

Key Features

• Core Electricals — 150 µF capacitance with ±20% tolerance and 80 V rated voltage for energy storage and decoupling at elevated voltages.
• Temperature & Endurance — Rated for -40 °C to 125 °C operation and specified for 3000 hours endurance at 125 °C (case sizes φ8 to φ12.5), supporting long-term high-temperature use.
• Low Loss / Frequency Performance — tan δ of 0.12 measured at 20 °C, 120 Hz (for 80 V rating) to control dissipation factor in AC conditions.
• ESR & Ripple Capability — ESR of 280 mΩ at 20 °C / 100 kHz, with low-frequency ripple current 350 mA (120 Hz) and high-frequency ripple current 700 mA (10 kHz) for effective ripple smoothing.
• Leakage & Reliability Metrics — Specified leakage current of 120 µA and endurance characteristics that limit capacitance change to within ±30% after life test conditions.
• Package & Assembly — Chip-type radial can SMD (φ12.5 × 13.5L) with surface-mount land size 1.28 × 1.28 cm and embossed carrier taping for automated placement; vibration resistant construction.
• Compliance — RoHS-compliant and AEC-Q200 qualified.

Typical Applications

• Automotive Power Electronics — Useful in automotive power systems where an 80 V rating, high-temperature tolerance (−40 °C to 125 °C), and AEC-Q200 qualification are required.
• On-board DC-DC Converter Outputs — Provides bulk and smoothing capacitance with rated ripple current capability and controlled ESR for converter output filtering.
• Harsh-Environment Electronics — Designed for assemblies that require vibration resistance and long-term operation at elevated temperatures up to 125 °C.

Unique Advantages

• High-voltage capacity: 80 V rating enables use in higher-voltage circuits without series stacking.
• High-temperature endurance: Specified 3000-hour endurance at 125 °C supports long-life operation in hot environments.
• Controlled dissipation and low ESR: tan δ of 0.12 and 280 mΩ ESR at 100 kHz reduce losses and improve high-frequency performance.
• Automated assembly ready: Embossed carrier taping and surface-mount radial can package simplify pick-and-place and reflow processes.
• Vibration resistant construction: Enhances reliability in mechanically demanding installations.
• Industry compliance: RoHS conformity and AEC-Q200 rating provide traceable compliance for regulated applications.
