UCM1E221MCS1GS

The UCM1E221MCS1GS is a chip-type, low-impedance aluminum electrolytic capacitor in a surface-mount can designed for automated assembly. It provides 220 µF capacitance at a 25 V rated voltage and is built for applications that require wide temperature operation and measurable ripple-handling capability.

Targeted for automotive and other demanding environments, this part combines a compact φ6.3 × 7.7 mm package, AEC-Q200 qualification, and a -55 °C to 105 °C operating range to deliver reliable decoupling and smoothing where space and durability matter.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Low Impedance Performance — Chip-type low impedance construction with a tangent of loss angle (tanδ) of 0.14 (measured at 20 °C, 120 Hz, 25 V) for efficient AC handling.
• Ripple Current Handling — Designed for 300 mA low-frequency ripple at 120 Hz and 600 mA high-frequency ripple at 10 kHz, supporting smoothing and decoupling in power circuits.
• Leakage Current — Specified leakage current of 55 µA after rated voltage application, allowing predictable standby and operating behavior.
• Wide Temperature & Endurance — Rated for -55 °C to 105 °C with an endurance spec of 2000 hours at 105 °C.
• Surface-Mount, Assembly-Friendly Package — Compact φ6.3 × 7.7 mm SMD can with embossed carrier taping for automatic pick-and-place mounting; vibration resistant.
• Automotive-Grade Qualification — AEC-Q200 rated for use in applications requiring industry-recognized component qualification.
• RoHS Compliant — Meets RoHS requirements for material compliance.

Typical Applications

• Automotive power modules — Provides local smoothing and decoupling where the AEC-Q200 qualification and -55 °C to 105 °C temperature range are required.
• Power supply filtering — Handles low- and high-frequency ripple currents (300 mA at 120 Hz, 600 mA at 10 kHz) for DC‑DC converters and regulator outputs.
• Compact, assembly-driven designs — Surface-mount chip can packaged in embossed carrier tape for automated placement in space-constrained boards.

Unique Advantages

• High ripple capability: Rated ripple currents up to 600 mA at 10 kHz support demanding filtering tasks in power rails.
• Low-loss AC performance: A measured tanδ of 0.14 at 25 V (120 Hz, 20 °C) reduces heat generation and improves efficiency in AC/stressed environments.
• Automotive-grade reliability: AEC-Q200 rating and 2000-hour endurance at 105 °C address long-term reliability needs in regulated industries.
• Compact SMD form factor: φ6.3 × 7.7 mm chip can reduces board area while enabling automated assembly via embossed carrier taping.
• Wide operating temperature: -55 °C to 105 °C supports use across harsh temperature conditions.
• Predictable leakage behavior: 55 µA leakage current specification aids in budgeted standby and power-loss analysis.
