UCX1E101MCS1GS

The UCX1E101MCS1GS is a chip-style aluminum electrolytic capacitor designed for surface-mount assemblies that require stable performance in elevated temperatures. It delivers 100 µF at 25 V in a compact SMD can package and is intended for applications where high-temperature endurance and reliable electrical behavior across a wide ambient range are required.

Built for demanding environments, this part combines a wide operating temperature range (−40 °C to +135 °C), an ESR specification verified after −40 °C testing, and AEC-Q200 qualification—making it suitable for automotive-grade and other high-temperature electronics where RoHS compliance is also required.

Key Features

• Electrical Performance 100 µF rated capacitance at 25 V with a tolerance of −20% to +20%, polarized design for DC filtering and smoothing tasks.
• Low‑temperature ESR Specification ESR specified after the −40 °C test and rated at 200 mΩ (measured at 100 kHz), supporting reliable behavior in cold-start conditions.
• Ripple Current Ratings Rated ripple current of 135 mA at 120 Hz and 270 mA at 10 kHz to support power-conditioning duties across different frequency ranges.
• Thermal Endurance Qualified for operation from −40 °C to +135 °C with an endurance rating of 2000 hours at 135 °C as specified in the datasheet.
• Package & Assembly Surface-mount radial can (chip type) compatible with automatic mounting machines fed from carrier tape; recommended PCB land size 8.3 × 8.3 mm.
• Compliance & Qualification AEC-Q200 Qualified and RoHS compliant (2011/65/EU, (EU)2015/863), suitable for regulated and reliability-focused designs.

Typical Applications

• Automotive electronics — Use in vehicle electronic modules where AEC-Q200 qualification and high-temperature operation are required.
• High-temperature electronic assemblies — Filtering and smoothing in designs exposed to elevated ambient temperatures up to +135 °C.
• Automated surface-mount production — Designed for placement from carrier tape on automatic mounting equipment to support high-volume assembly.

Unique Advantages

• High-temperature reliability: Rated for continuous operation to +135 °C with a 2000-hour endurance at that temperature, providing predictable long-term behavior in hot environments.
• Cold-condition ESR verification: ESR specified after −40 °C testing and measured at 100 kHz (200 mΩ), helping maintain performance across the full temperature range.
• Automated assembly compatibility: Carrier-tape compatible chip form factor simplifies pick-and-place integration for high-volume production.
• Automotive-grade qualification: AEC-Q200 status supports use in regulated automotive designs that demand component-level reliability documentation.
• Measured ripple capability: Documented ripple current ratings at both low and high frequencies (120 Hz and 10 kHz) allow designers to match the part to specific power-conditioning needs.
• Regulatory compliance: RoHS compliant to 2011/65/EU and (EU)2015/863 requirements for use in controlled markets.
