UCJ1V101MCL1GS

The UCJ1V101MCL1GS is a chip-type aluminum electrolytic capacitor from Nichicon’s UCJ series designed for high-temperature operation. It delivers 100 µF capacitance at a 35 V rating in a compact surface-mount radial-can package engineered for automated tape-fed assembly.

Engineered for demanding environments, this capacitor combines high operating temperature capability (−40 °C to +125 °C), defined low-temperature ESR performance, and AEC-Q200 qualification to address automotive and other high-reliability power applications.

Key Features

• Capacitance and Voltage — 100 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• High-Temperature Performance — Rated for continuous use from −40 °C to +125 °C with endurance specified as 2000 hours at 125 °C under rated voltage.
• Low-Temperature ESR Specification — ESR specification added and validated after a −40 °C test to ensure performance at low ambient temperatures; impedance ratio Z(−40 °C)/Z(+20 °C) for the 35 V rating is specified as 4.
• Ripple Current Capability — Ripple current specifications include 200 mA at 120 Hz and 400 mA at 10 kHz, supporting smoothing and decoupling across low and high frequencies.
• Surface-Mount, Tape-Fed Compatible — Chip-type radial can SMD package sized approximately 1 × 1 cm with surface-mount land recommendation (1.03 × 1.03 cm), compatible with automatic mounting machines fed by carrier tape.
• Reliability and Robustness — AEC-Q200 qualification and RoHS compliance; endurance, shelf-life, and resistance-to-soldering-heat characteristics are specified in the UCJ series datasheet.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification plus −40 °C to +125 °C range make it suitable for vehicle electronic control modules and other automotive power systems requiring high-temperature durability.
• Power Supply Filtering — 100 µF at 35 V with defined ripple current ratings supports bulk smoothing and output filter duties in DC–DC converters and power rails.
• Automated PCB Assembly — Designed for surface-mount placement from carrier tape, enabling efficient use in automated production for high-volume electronics manufacturing.

Unique Advantages

• High-temperature endurance: Specified for 2000 hours at 125 °C, providing defined long-term performance under elevated thermal stress.
• AEC-Q200 qualified: Certification supports use in automotive-grade designs where industry-standard component qualification is required.
• Validated low-temperature behavior: ESR specification after −40 °C testing and impedance limits help ensure predictable performance in cold conditions.
• Dual-frequency ripple handling: Rated ripple currents at 120 Hz and 10 kHz enable effective filtering across both line-frequency and switching-frequency domains.
• Production-friendly package: Tape-fed, surface-mount radial-can format simplifies pick-and-place integration in automated assembly lines.
• Standards-compliant: RoHS-compliant construction aligns with environmental regulatory requirements.
