UUE1C681MNS1MS

The UUE1C681MNS1MS is a chip‑type aluminum electrolytic capacitor in a compact surface‑mount radial can package. It provides 680 µF capacitance at 16 V with polarization and is designed for sustained operation in high‑temperature environments.

Key value comes from long load life and automotive‑grade reliability: the device is AEC‑Q200 qualified, RoHS compliant, and specified for 5000 hours at 125 °C, making it suitable for demanding electronic applications that require extended high‑temperature endurance.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance with ±20% tolerance at 16 V, providing bulk energy storage in compact SMD designs.
• High‑Temperature Endurance — Rated for operation from −55 °C to 125 °C with a specified load life of 5000 hours at 125 °C; after endurance testing, capacitance change remains within ±30% and leakage current stays within specified limits.
• Automotive Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant, supporting use in automobile electronics where heavy‑duty service is required.
• Package & Mounting — Surface‑mount radial can (chip type) with dimensions L: 16.5 mm × D: 16 mm (1.65 cm × 1.6 cm) and surface mount land size 16.3 mm × 16.3 mm for compact board integration.
• Ripple Current Capability — Specified ripple handling of 670 mA at 120 Hz and 1 A at 10 kHz; datasheet lists 1000 mArms rated ripple at 125 °C/100 kHz for this part number.
• Leakage & Loss Characteristics — Leakage current defined as not more than 0.03CV (µA) after 1 minute at 20 °C; tangent of loss angle (tan δ) for 16 V is specified with a maximum of 0.18 at 120 Hz, 20 °C.

Typical Applications

• Automotive electronics — Suited for automobile electronics where heavy‑duty service is indispensable, providing bulk smoothing and energy buffering under elevated temperatures and vibration conditions.
• High‑temperature electronics — Designed for circuits that must operate reliably up to 125 °C for extended periods, supporting long life under thermal stress.
• Surface‑mount power modules — Compact radial can SMD package enables use in board‑level power stages and modules where high capacitance and ripple handling are required in a small footprint.

Unique Advantages

• Long high‑temperature life — 5000 hours specified at 125 °C reduces the need for frequent redesigns or replacements in thermally demanding applications.
• Automotive‑grade assurance — AEC‑Q200 qualification supports deployment in automotive systems that require defined reliability and qualification flows.
• Compact, board‑friendly form — Chip‑type radial can SMD package with defined land pattern simplifies mechanical integration into compact assemblies.
• Clear electrical limits — Defined leakage, tan δ, and impedance characteristics at specified temperatures and frequencies help with predictable power‑stage sizing and thermal management.
• Regulatory compliance — RoHS compliance supports designs that require restriction of hazardous substances.
