UCX1E331MCS1GS

The UCX1E331MCS1GS is a chip-type aluminum electrolytic capacitor designed for high-temperature operation up to 135°C. It delivers 330 µF at 25 V in a compact surface-mount radial can package intended for automated assembly and high-reliability applications.

Engineered for environments that require temperature resilience and long endurance, this capacitor is suited to automotive and other high-temperature electronic systems where AEC-Q200 qualification, explicit low-temperature ESR characterization, and RoHS compliance are required.

Key Features

• Temperature Range and Endurance – Rated for operation from −40°C to +135°C with an endurance specification of 2000 hours at 135°C under rated voltage.
• Capacitance and Voltage – 330 µF nominal capacitance with a rated voltage of 25 V and tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• ESR and Low-Temperature Performance – Equivalent series resistance specified at 150 mΩ (measured at 100 kHz) and ESR behavior characterized after −40°C testing.
• Ripple Current Ratings – Rated ripple current of 250 mA at 120 Hz and 500 mA at 10 kHz for AC performance planning.
• Reliability Characteristics – Endurance limits include capacitance change within ±30% and tan δ within 300% of initial specified value after the 2000 h, 135°C test; leakage current meets initial specified limits.
• Surface-Mount Packaging and Assembly – Chip-type radial can SMD packaged for surface mount mounting; compatible with automatic mounting machines using carrier tape and suitable for soldering heat processes specified in the datasheet.
• Qualification and Compliance – AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronic Modules – Use in power and control modules that require components qualified to AEC-Q200 and rated for continuous operation at elevated temperatures.
• High-Temperature Electronics – Suitable for circuits and systems that operate in environments up to +135°C where long-term endurance is required.
• Automated Surface-Mount Production – Designed for use in production lines employing carrier-tape fed automatic mounting machines, supporting efficient PCB assembly.

Unique Advantages

• High-Temperature Endurance: Specified 2000 hours at 135°C provides a quantified reliability metric for thermal stress planning.
• Measured Low-Temperature ESR: ESR is specified after −40°C testing, enabling designers to assess performance across the full rated temperature range.
• Practical Ripple Handling: Dual ripple current specifications (120 Hz and 10 kHz) help size capacitors for both low- and high-frequency ripple conditions.
• Surface-Mount Assembly Ready: Carrier-tape compatibility and SMD can packaging support streamlined automated assembly processes.
• Industry Qualification: AEC-Q200 qualification and RoHS compliance support integration into regulated and environmentally constrained designs.
