The UUJ1H102MNQ1MS from Nichicon is a chip-type aluminum electrolytic capacitor in the UUJ series, offering 1 mF capacitance at a 50 V rating in a surface-mount can package. It is designed for high-density PC board assembly and is compatible with automatic mounting machines fed with carrier tape.

With AEC-Q200 qualification and RoHS compliance, this part targets applications that require higher capacitance in surface-mount form factors while maintaining high-temperature endurance and defined ripple performance.

Key Features

• Electrical Rating: 1 mF rated capacitance at 50 V with ±20% tolerance; polarized aluminum electrolytic construction.
• Package & Mounting: Chip-type radial, can SMD package designed for surface mounting on high-density PC boards; compatible with automatic mounting machines fed with carrier tape. Surface-mount land size: 1.83 × 1.83 cm.
• Size: Physical footprint L: 2.15 × D: 1.8 cm for board-level placement.
• Temperature & Lifetime: Operating temperature range −55°C to +105°C; endurance rated for 5000 hours at 105°C with specified post-test limits for capacitance, tan δ, and leakage current.
• Ripple Performance: Rated ripple current of 820 mA at 120 Hz and 943 mA at 10 kHz, supporting AC current handling at both low and high frequencies.
• Compliance & Qualification: AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), meeting recognized reliability and environmental requirements.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and high-temperature endurance make this capacitor suitable for automotive electronic modules requiring robust, long-duration performance at elevated temperatures.
• High-Density PCB Assemblies — Chip-type SMD can package and carrier-tape compatibility enable automated placement on dense boards where board space and assembly efficiency matter.
• Board-Level Power Subsystems — Provides higher capacitance in larger SMD case sizes (φ12.5, φ16, φ18) for board designs that require increased capacitance in SMD form.

Unique Advantages

• Higher Capacitance in SMD Form: UUJ series offers increased capacitance in larger chip-type case sizes (φ12.5, φ16, φ18), enabling designers to keep capacitance high while staying with surface-mount assembly.
• Automated Assembly Ready: Designed for use with automatic mounting machines fed with carrier tape, reducing assembly handling and improving production throughput.
• High-Temperature Endurance: Rated for 5000 hours at 105°C, delivering predictable long-term characteristics under elevated temperature stress.
• Defined Ripple Capability: Specified ripple currents at both 120 Hz and 10 kHz give clear guidance for AC current handling in filtering and decoupling scenarios.
• Industry Qualification and Environmental Compliance: AEC-Q200 qualification combined with RoHS compliance supports deployment in regulated and reliability-focused markets.
