UCZ1E101MCL6GS

The UCZ1E101MCL6GS is a high-reliability, chip-type aluminum electrolytic capacitor designed for surface-mount assembly and long-term operation at elevated temperatures. It is a polarized SMD capacitor specified for operation from -40 °C to +125 °C, with performance and endurance characteristics targeted at demanding power applications.

Key value propositions include AEC-Q200 qualification, a low-temperature ESR specification (with ESR specified after a -40 °C test), and suitability for automated placement using carrier tape—making it appropriate where durability, temperature resilience, and automated manufacturing are required.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• High-temperature operation — Specified operating temperature range from -40 °C to +125 °C, and endurance specified for 2000 hours at 125 °C.
• Low-temperature ESR — Low-temperature ESR specification with an added ESR check after the -40 °C test; specific ESR value: 450 mΩ measured at 100 kHz.
• Ripple current capability — Rated ripple current of 98.5 mA at 120 Hz and 197 mA at 10 kHz for handling AC stress on power rails.
• Package & mounting — Chip-type, surface-mount radial can (SMD) package sized 7.7 × 6.3 mm (L × D). Designed for automatic mounting machines fed with carrier tape; recommended PCB land size 6.6 × 6.6 mm.
• Reliability & compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), with endurance, leakage, and soldering-heat characteristics defined for robust assemblies.

Typical Applications

• Automotive electronics — Power rail decoupling and smoothing in modules where AEC-Q200 qualification and +125 °C capability are required.
• DC/DC converters and power supplies — Output filtering and bulk decoupling that benefit from 100 µF capacitance, specified ripple current, and elevated-temperature endurance.
• Industrial control systems — Power conditioning in controllers and motor drivers operating in elevated ambient temperatures up to +125 °C.
• Embedded power subsystems — Local energy storage and transient suppression on boards assembled with automated pick-and-place processes.

Unique Advantages

• High-temperature endurance: Rated for operation to +125 °C with 2000 hours of endurance at that temperature, enabling sustained use in hot environments.
• Qualification for demanding applications: AEC-Q200 qualification provides documented reliability criteria for use in regulated environments.
• Verified low-temperature behavior: ESR is specified after a -40 °C test, providing assurance of performance across the full -40 °C to +125 °C range.
• Surface-mount, automated assembly ready: Chip-type can packaged for carrier-tape feeding and automatic placement, simplifying high-volume manufacturing.
• Measurable AC performance: Specified ripple currents at 120 Hz and 10 kHz and a measured ESR (450 mΩ at 100 kHz) help designers size filters and thermal budgets precisely.
• Standards compliance: RoHS compliance supports regulatory requirements for lead-free assemblies.
