UUD1A101MCL1GS

The UUD1A101MCL1GS is a chip-type, low-impedance aluminum electrolytic capacitor from Nichicon's UUD series, specified for surface-mount use on high-density PC boards. It combines a compact SMD radial-can package with manufacturing-friendly features such as carrier-tape compatibility and automated placement suitability.

Designed for demanding operating environments, this part is rated for -55 °C to +105 °C, carries AEC-Q200 qualification, and is RoHS compliant—making it appropriate for applications where temperature endurance, reliability, and regulatory compliance are required.

Key Features

• Capacitance & Voltage — Rated at 100 µF and 10 V with a capacitance tolerance of ±20% (−20% to +20%).
• Low Impedance Performance — Specified impedance of 440 mΩ, providing reduced AC voltage drop in filtering and decoupling roles.
• Ripple Current Capability — Supports 230 mA ripple current at 105 Hz and 345 mA at 10 kHz, enabling effective handling of low- and high-frequency AC components.
• Thermal and Endurance Ratings — Operating range from -55 °C to +105 °C with a rated lifetime of 2000 hours at 105 °C (as specified for this size), suitable for sustained elevated-temperature operation.
• Mounting & Package — Chip-type radial can for surface mounting; package dimensions L: 5.8 × D: 6.3 mm with recommended PCB land size of 6.6 × 6.6 mm; compatible with automatic mounting machines fed by carrier tape.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulated and reliability-focused designs.
• Polarized Electrolytic — Polarized capacitor intended for DC use per standard electrolytic polarity requirements.
• Leakage Current Specification — Leakage current meets the datasheet condition: after 2 minutes' application of rated voltage at 20 °C, leakage is ≤ 0.01 CV or 3 µA (whichever is greater).

Typical Applications

• Automotive electronics — AEC-Q200 qualification and wide temperature range enable use in vehicle electronic modules where board space and reliability are critical.
• High-density SMD assemblies — Chip-type radial-can design and carrier-tape compatibility make the part suitable for automated placement on compact PCBs.
• Temperature-challenged systems — Rated operation to +105 °C and a specified endurance at elevated temperature support use in hot-environment electronics assemblies.
• Filtered power rails — Low impedance and defined ripple current ratings support smoothing and decoupling duties on constrained power domains.

Unique Advantages

• Compact SMD form factor: Small L × D footprint (5.8 × 6.3 mm) saves board space while retaining useful capacitance.
• Manufacturing-ready: Carrier-tape compatibility and surface-mount packaging simplify automated assembly and throughput.
• High-temperature endurance: Specified lifetime of 2000 hours at 105 °C provides predictable performance in elevated-temperature applications.
• Regulatory and reliability credentials: RoHS compliance and AEC-Q200 qualification support deployment in regulated and quality-driven designs.
• Balanced AC performance: Defined impedance and ripple current specs at both low and high frequencies help manage transient and switching ripple on power rails.
