UCX1C331MCS1GS

The UCX1C331MCS1GS is a chip-type aluminum electrolytic capacitor in a surface-mount, radial can package designed for high-reliability applications. It delivers 330 µF at 16 V in a compact 10×10 mm footprint with a rated operating range from -40°C to +135°C.

Designed for automated production, this part combines a low-temperature ESR specification, vibration resistance and AEC-Q200 qualification to address demanding automotive and high-temperature electronics use cases where long endurance and consistent electrical performance are required.

Key Features

• Capacitance & Voltage — 330 µF capacitance at a rated voltage of 16 V with ±20% tolerance, suited for bulk decoupling and energy storage in compact designs.
• Temperature & Endurance — Rated for -40°C to +135°C operation with an endurance of 2000 hours at 135°C, providing documented high-temperature reliability.
• Low-temperature ESR Specification — Specified tanδ of 0.23 at 16 V and low-temperature ESR behavior to maintain performance down to -40°C.
• Electrical Characteristics — Equivalent series resistance of 150 mΩ (measured at 100 kHz) and ripple current ratings of 250 mA at 120 Hz and 500 mA at 10 kHz.
• Leakage & Polarization — Polarized device with a measured leakage current of 52.8 µA and standard aluminum electrolytic leakage characteristics.
• Package & Assembly — 10×10 mm (L×D) chip-type radial can SMD with embossed carrier taping for automated pick-and-place and mass-production workflows.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant for regulated-environment use and automotive-capable applications.

Typical Applications

• Automotive Electronics — Use in vehicle electronic modules that require AEC-Q200 qualification and high-temperature endurance.
• Power Conversion — Bulk smoothing and energy storage in DC–DC converters and power supplies operating in elevated temperature environments.
• Vibration-prone Environments — Designs where vibration resistance and robust SMD packaging are needed for reliable long-term operation.
• High-volume Surface-mount Production — Embossed carrier taped packaging optimizes automated assembly for mass-production electronics.

Unique Advantages

• High-temperature endurance: 2000 hours at 135°C provides a verifiable performance baseline for sustained high-temperature operation.
• Automotive-grade qualification: AEC-Q200 rating supports use in automotive and other demanding system-level applications.
• Low-temperature performance: Low-temperature ESR specification and a tanδ of 0.23 help maintain stable behavior down to -40°C.
• Compact SMD footprint: 10×10 mm package enables space-efficient board designs while providing high capacitance for the size.
• Production-ready packaging: Embossed carrier taping and SMD compatibility streamline automated assembly and reduce handling complexity.
• Documented electrical specs: ESR (150 mΩ at 100 kHz), ripple current ratings, and measured leakage current (52.8 µA) give clear parameters for power-electronics design.
