UCH1V331MCL1GS

The UCH1V331MCL1GS is a high-reliability, chip-type aluminum electrolytic capacitor in a surface-mount can. It delivers 330 µF at 35 V with polarized construction and is designed for use in systems that require qualified components and robust thermal performance.

Key value comes from its extended temperature range (−40°C to 125°C), AEC-Q200 qualification, low-temperature ESR specification, and compatibility with automated PCB assembly processes.

Key Features

• Electrical Performance — 330 µF capacitance at 35 V with ±20% tolerance; polarized aluminum electrolytic construction.
• Low-Temperature ESR — Specified ESR of 150 mΩ at 100 kHz and an added ESR specification after the −40°C test to maintain performance in cold environments.
• Ripple Current Handling — Rated ripple current of 250 mA at 120 Hz and 500 mA at 10 kHz, with published frequency coefficients for ripple-current scaling.
• Temperature and Lifetime — Operating range −40°C to +125°C with endurance rating of 2000 hours at 125°C; endurance limits include capacitance change within ±30% and leakage current within initial specification after test.
• Reliability & Qualification — AEC-Q200 qualified and RoHS compliant, with leakage current specified as not more than 0.01CV (µA) after 2 minutes at 20°C.
• Surface-Mount Packaging — Chip-type, radial can SMD package designed for automatic mounting machines fed with carrier tape; case marked with black print on the top for clear identification.
• Board Design Dimensions — Component size L: 1 × D: 1 cm with recommended surface-mount land size L: 1.03 × W: 1.03 cm.

Typical Applications

• Automotive systems — Suited for automotive electronic modules where AEC-Q200 qualification and wide temperature range are required.
• Surface-mount production — Designed for automated PCB assembly using carrier-tape fed pick-and-place equipment.
• High-temperature endurance modules — Appropriate for designs that require sustained operation up to 125°C and defined 2000-hour endurance performance.

Unique Advantages

• Qualified for demanding environments: AEC-Q200 qualification provides documented reliability for qualified electronic applications.
• Low-temperature performance: Added ESR specification after −40°C testing and a measured ESR of 150 mΩ at 100 kHz reduce uncertainty in cold-start or low-temperature conditions.
• Clear thermal and lifetime specs: Rated for −40°C to +125°C operation with a 2000-hour endurance rating at 125°C, enabling predictable long-term behavior.
• Automated assembly ready: Chip form factor and carrier-tape compatibility simplify integration into high-volume surface-mount production flows.
• RoHS compliant: Meets current RoHS directive requirements for material compliance.
• Documented ripple performance: Published ripple-current ratings and frequency coefficients support accurate thermal and ripple budgeting in designs.
