UUE1E681MNS1MS

The UUE1E681MNS1MS is a chip-type aluminum electrolytic capacitor designed for demanding high-temperature applications. It delivers 680 µF capacitance at a 25 V rating in a compact surface-mount radial can (SMD) package.

Engineered for heavy-duty automotive electronics and other high-temperature systems, this capacitor offers a 5000-hour rated life at 125°C, AEC-Q200 qualification, and RoHS compliance for regulated manufacturing environments.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 25 V for bulk energy storage and filtering in power subsystems.
• High-temperature Endurance — Rated lifetime of 5000 hours at 125°C to support long-term operation in elevated-temperature assemblies.
• Automotive-grade Qualification — AEC-Q200 Qualified, indicating suitability for automotive electronic applications where qualification is required.
• Wide Operating Temperature — Performance specified from –55°C to +125°C for broad environmental tolerance.
• Ripple Current Performance — Rated ripple handling of 804 mA at 120 Hz and 1.2 A at 10 kHz to support power smoothing under AC and switching loads.
• Package & Assembly — Surface-mount, radial can (SMD) package with compact footprint: L 1.65 cm × D 1.8 cm and recommended land size 1.83 × 1.83 cm for board-level assembly.
• Polarized Electrolytic — Polarized construction with ±20% capacitance tolerance at 120 Hz, 20°C for predictable bulk capacitance behavior.
• Regulatory Compliance — RoHS compliant (2011/65/EU & (EU)2015/863) for use in restricted-substance environments.

Typical Applications

• Automotive electronic modules — Bulk smoothing and decoupling in ECUs, power converters and control modules where high-temperature durability and AEC-Q200 qualification are required.
• Power supply filtering — Energy storage and ripple suppression in DC–DC converters and power distribution networks exposed to elevated operating temperatures.
• High-temperature assemblies — Components for systems that undergo high-temperature reflow and sustained elevated-temperature operation, benefiting from the 125°C endurance rating.

Unique Advantages

• Long life at elevated temperature: 5000 hours rated at 125°C provides proven endurance for thermally challenging designs.
• Automotive-grade reliability: AEC-Q200 qualification supports use in automotive electronics and other reliability-focused applications.
• High capacitance in a compact SMD can: 680 µF in a 1.65 × 1.8 cm package reduces board area compared with larger radial designs while retaining bulk capacitance.
• Strong ripple-handling capability: Specified ripple currents at 120 Hz and 10 kHz support both low-frequency and switching-power applications.
• Wide temperature range: –55°C to +125°C operating range enables use across a broad set of environmental conditions.
• RoHS compliance: Meets current restricted-substance directives for regulated production environments.
