UCM1E151MCS1GS

The UCM1E151MCS1GS is a chip-type, low-impedance aluminum electrolytic capacitor in a surface-mount can package designed for compact, automated assembly. It delivers 150 µF capacitance at a 25 V rating with specified ripple, leakage, and endurance characteristics suited to demanding operating environments.

Targeted use includes automotive and other applications that require AEC-Q200-rated components, wide operating temperature range, and compatibility with automated carrier-tape pick-and-place processes.

Key Features

• Capacitance & tolerance — 150 µF nominal capacitance with tolerance of −20% to +20% at 120 Hz, 20°C.
• Rated voltage — 25 V working voltage for board-level energy storage and decoupling in compact designs.
• Low impedance / dissipation — Chip-type, low-impedance construction with tanδ (DF) of 0.14 measured at 20°C, 120 Hz.
• Ripple current capability — Low-frequency ripple current 300 mA (120 Hz) and high-frequency ripple current 600 mA (10 kHz) specifications to support dynamic loads.
• Leakage current — Maximum leakage current of 37.5 µA after 2 minutes at rated voltage, 20°C.
• Temperature and endurance — Operating range −55°C to +105°C and rated life of 2000 hours at 105°C.
• Package & mounting — Surface-mount radial can (φ6.3 × 7.7 mm) compatible with embossed carrier taping for automatic mounting machines; recommended land size 6.6 × 6.6 mm.
• Reliability & compliance — AEC-Q200 rated and RoHS compliant; vibration resistant construction.

Typical Applications

• Automotive electronics — Suited for board-level energy storage and filtering in automotive systems where AEC-Q200 qualification is required.
• Automated SMT assembly — Packaged in embossed carrier tape for compatibility with automatic mounting machines and high-volume production.
• Vibration-prone modules — Vibration resistant construction supports use in environments subject to mechanical stress.

Unique Advantages

• Chip-type low impedance — Designed for reduced impedance with a specified tanδ of 0.14 (25 V, 20°C, 120 Hz), aiding stable performance in frequency-sensitive circuits.
• Dual-frequency ripple handling — Specified ripple current at both low and high frequencies (300 mA at 120 Hz; 600 mA at 10 kHz) supports a range of dynamic load conditions.
• Wide temperature and proven endurance — −55°C to +105°C operating range with 2000-hour endurance at 105°C for sustained high-temperature operation.
• Automotive-grade qualification — AEC-Q200 rating enables use in automotive designs that require qualified components.
• Assembly-ready packaging — Embossed carrier taping and an SMD-compatible can (φ6.3 × 7.7 mm) streamline automated placement and reduce handling complexity.
