UCX1A221MCL1GS

The UCX1A221MCL1GS is a chip-type aluminum electrolytic capacitor in Nichicon’s UCX series designed for high-temperature operation. It delivers 220 µF at 10 V in a compact surface-mount can package with specifications targeted for automotive and other high-temperature electronics.

Engineered for reliability, this part is AEC-Q200 qualified, RoHS compliant, and rated for operation from –40 °C to +135 °C. The device includes an ESR specification verified after a –40 °C test and is compatible with automated assembly using carrier tape.

Key Features

• Core Electricals — 220 µF nominal capacitance at 10 V with ±20% tolerance, providing bulk capacitance in a compact SMD can.
• Low‑temperature ESR Characterization — ESR specified at 200 mΩ measured at 100 kHz, with an ESR specification added after testing at –40 °C to ensure low-temperature performance is defined.
• Ripple Handling — Rated ripple current of 135 mA at 120 Hz and 270 mA at 10 kHz to quantify AC stress capability across common frequencies.
• High‑Temperature Endurance — Endurance rating of 2000 hours at +135 °C with specified capacitance, tan δ and leakage current criteria after recovery to 20 °C.
• Surface‑Mount Packaging — Chip-style SMD can (radial, can - SMD) suited for automated placement; surface mount land size 8.3 × 8.3 mm and compact dimensions (L: 1 × D: 0.8 cm).
• Soldering Heat Resistance — Designed to meet characteristic requirements after exposure to 250 °C hot-plate conditions for 30 seconds, per the series test data.
• Quality & Compliance — AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulated and automotive programs.

Typical Applications

• Automotive electronic control units (ECUs) — AEC‑Q200 qualification and a –40 °C to +135 °C operating range make this capacitor suitable for use in automotive control modules where defined high-temperature endurance is required.
• Power management and DC–DC converter modules — 220 µF capacitance combined with a specified ESR (200 mΩ at 100 kHz) and measured ripple current ratings provides quantifiable smoothing and ripple-handling capability for low-voltage power rails.
• High-temperature surface-mount assemblies — Chip-type SMD can packaged for carrier-tape automated placement and tested for soldering heat resistance, supporting high-throughput manufacturing processes.

Unique Advantages

• Defined performance at extreme temperatures: Rated for –40 °C to +135 °C with endurance testing at 135 °C for 2000 hours, giving designers quantified high-temperature reliability.
• Low-temperature ESR validation: ESR specification includes post –40 °C test results, providing predictable behavior under cold-start conditions.
• Quantified ripple and ESR specs: Published ripple current values (135 mA @120 Hz, 270 mA @10 kHz) and 200 mΩ ESR at 100 kHz allow direct comparison when specifying for power-supply decoupling.
• Automated assembly ready: Compatible with automatic mounting machines fed with carrier tape and provided in a compact SMD can package to streamline PCB assembly.
• Automotive-grade qualification: AEC‑Q200 qualification supports use in regulated automotive programs where that level of component qualification is required.
• Standards compliance: RoHS compliant to 2011/65/EU and (EU)2015/863, supporting regulatory conformity in end products.
