UCN1V151MCL1GS

The UCN1V151MCL1GS is a chip-type aluminum electrolytic capacitor designed for high reliability and long life in surface-mount applications. It provides 150 µF capacitance at a 35 V rating with low ESR characteristics and AEC-Q200 qualification for demanding environments.

Its combination of compact SMD can packaging, -40 °C to 125 °C operating range, and specified ripple performance make it suitable for automotive electronics and other high-reliability power applications.

Key Features

• Capacitance & Voltage — 150 µF rated capacitance with a 35 V rated voltage and ±20% tolerance.
• Low ESR — Equivalent Series Resistance of 500 mΩ at 100 kHz to help reduce losses and improve ripple handling.
• High temperature endurance — Rated for operation from -40 °C to 125 °C with a guaranteed lifetime of 3000 hours at 125 °C.
• Ripple performance — Specified ripple current: 98.5 mA at 120 Hz and 197 mA at 10 kHz (frequencies and coefficients defined in the series datasheet).
• Chip-type SMD package — Radial, can-style surface-mount package (φ6.3 × 7.7 mm) designed for automatic mounting machines fed with carrier tape.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU,(EU)2015/863), supporting high-reliability system requirements.
• Polarized aluminum electrolytic — Standard polarized construction for bulk decoupling and power smoothing applications.

Typical Applications

• Automotive electronic modules — AEC-Q200 qualification and the -40 °C to 125 °C range make this capacitor suitable for electronic control modules and other automotive power subsystems.
• Surface-mount power assemblies — Chip-type can package and compatibility with automatic mounting machines support high-density SMD power boards and automated production.
• High-temperature environments — Designed and rated for sustained operation and endurance testing at elevated temperature (3000 h at 125 °C), for applications exposed to high thermal stress.

Unique Advantages

• AEC-Q200 qualified reliability: Provides the documented qualification needed for high-reliability and automotive-focused designs.
• Low ESR for improved ripple handling: 500 mΩ at 100 kHz reduces internal losses and supports stable power delivery in cluttered supply rails.
• High-temperature endurance: 3000 hours at 125 °C enables designs that must tolerate prolonged elevated-temperature operation.
• Compact SMD can footprint: φ6.3 × 7.7 mm package saves board space while remaining compatible with automated pick-and-place and carrier-tape feeding.
• Clear compliance: RoHS conformity simplifies environmental compliance for regulated markets.
