UCX1C221MCL1GS

The UCX1C221MCL1GS is a chip-type aluminum electrolytic capacitor from Nichicon's UCX series, offering 220 µF capacitance at a 16 V rating in a compact surface-mount can package. It is designed for high-reliability applications requiring extended operation across a wide temperature range and is suitable for automated assembly processes.

Key value comes from its high-temperature endurance (rated for use to +135°C), AEC-Q200 qualification, and low-temperature ESR characterization, providing predictable performance in demanding thermal environments.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance, suitable for bulk decoupling and energy storage in compact SMD form factors.
• High-temperature endurance — Rated for continuous operation from -40°C to +135°C with a specified lifetime of 2000 hours at 135°C.
• Low-temperature ESR specification — ESR specified as 200 mΩ at 100 kHz and characterized after testing at -40°C for reliable low-temperature performance.
• Ripple handling — Low-frequency ripple current rating of 135 mA at 120 Hz and high-frequency ripple current rating of 270 mA at 10 kHz, supporting a range of power-conditioning duties.
• Surface-mount, automated assembly ready — Chip-type SMD can package designed for automatic mounting machines fed with carrier tape; recommended surface-mount land size 8.3 × 8.3 mm.
• Compliance & qualification — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863) for regulated markets.
• Compact footprint — Physical size L: 10 mm × D: 8 mm with a seated height limit of 10 mm, enabling space-efficient board layouts.

Typical Applications

• Automotive systems — AEC-Q200 qualification and extended high-temperature rating make the part suitable for automotive electronic modules that require reliable decoupling and bulk capacitance.
• High-temperature electronics — With guaranteed operation to +135°C and a 2000 hour endurance at that temperature, this capacitor supports electronics exposed to elevated operating temperatures.
• Surface-mount, high-density assemblies — Chip can package and carrier-tape compatibility enable efficient placement in automated SMD production for power and control boards.

Unique Advantages

• High-temperature reliability: 2000 hours rated lifetime at 135°C provides measurable endurance for thermal stress conditions.
• Temperature-characterized ESR: ESR value specified after -40°C testing ensures predictable behavior across the full -40°C to +135°C operating range.
• Automated assembly ready: Designed for carrier-tape feed to automatic mounting machines, reducing manual handling and speeding production.
• Regulatory and industry qualification: AEC-Q200 qualification and RoHS compliance support use in regulated and safety-conscious designs.
• Compact SMD can package: Small L × D footprint and defined surface-mount land size enable tight PCB placement and straightforward layout.
• Measured ripple capability: Specified ripple currents at both low and high frequencies allow designers to size the capacitor to expected ripple loads.
