The UCH1E331MCS1GS is an aluminum electrolytic, chip-type capacitor engineered for high-reliability applications. It is a surface-mount, carrier-tape compatible device with a rated capacitance of 330 µF at 25 V and a capacitance tolerance of ±20%.

Designed for demanding thermal and mechanical environments, the part is AEC-Q200 qualified, RoHS compliant, and specified to operate from −40 °C to 125 °C with endurance validated for 2000 hours at 125 °C. The series includes low-temperature ESR specifications with ESR measured at 200 mΩ (100 kHz) for this part.

Key Features

• Electrical Rating — 330 µF nominal capacitance at 25 V with ±20% tolerance (measured at 120 Hz, 20 °C).
• Low-temperature ESR specification — ESR characterized after −40 °C testing; part ESR specified at 200 mΩ at 100 kHz.
• Wide operating temperature — Rated for operation from −40 °C to 125 °C with endurance specified for 2000 hours at 125 °C.
• Ripple current performance — Rated ripple currents of 135 mA at 120 Hz and 270 mA at 10 kHz; frequency coefficients (series data) allow scaling across frequencies.
• Leakage current specification — Leakage current after 2 minutes at rated voltage and 20 °C is specified as not more than 0.01CV (µA), per the series datasheet.
• SMD-ready package and assembly — Chip (radial, can-style SMD) package designed for surface-mount assembly and compatible with automatic mounting machines fed with carrier tape.

Typical Applications

• Automotive electronics — AEC-Q200 qualification and −40 °C to 125 °C rating make this capacitor suitable for automotive control modules and electronic subsystems that require automotive-grade components.
• Automated surface-mount production — Carrier-tape compatibility and SMD can packaging support high-throughput automated assembly processes.
• High-temperature electronics — Endurance of 2000 hours at 125 °C and soldering-heat resistance meet the needs of systems exposed to elevated operating temperatures.

Unique Advantages

• AEC-Q200 qualification — Provides recognized automotive-grade qualification for designs targeting vehicle systems.
• Verified low-temperature ESR — ESR specified after −40 °C testing, enabling designers to account for low-temperature behavior with documented data.
• High-temperature endurance — Endurance performance specified for 2000 hours at 125 °C supports long-term reliability in elevated-temperature applications.
• SMD and assembly-friendly — Case and tape-feed compatibility simplify integration into automated surface-mount manufacturing flows.
• Clear electrical specifications — Measured leakage current formula and frequency-rated ripple current values (120 Hz and 10 kHz) enable accurate thermal and lifetime calculations.
