UUE1A681MNS1MS

The UUE1A681MNS1MS is a chip-type aluminum electrolytic capacitor from Nichicon’s UUE series, designed for demanding environments. It provides 680 µF capacitance at a 10 V rating in a compact surface-mount radial can package.

Engineered for heavy-duty automotive electronics and other high-temperature applications, this capacitor offers long-term endurance with a rated operating range of −55 °C to 125 °C and a load life of 5000 hours at 125 °C. It is AEC‑Q200 qualified and RoHS compliant.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 10 V rated voltage and polarization suitable for power rail decoupling and energy storage.
• Temperature & Long Life — Rated for −55 °C to 125 °C with a specified load life of 5000 hours at 125 °C, enabling reliable operation in high-temperature systems.
• Automotive Qualification — AEC‑Q200 qualified, supporting use in automotive electronic modules where qualification is required.
• Package & Mounting — Surface-mount, radial can (chip) construction for PCB-mounted designs; footprint land size L: 1.28 × W: 1.28 cm and part size L: 1.6 × D: 1.25 cm.
• High Ripple Handling — Rated ripple current of 603 mA at 120 Hz and 900 mA at 10 kHz to support power-supply smoothing and switching regulator applications.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), meeting current restricted-substance requirements.
• Tolerance & Polarization — Capacitance tolerance of −20% to +20% and polarized construction; designers should observe polarity during placement.

Typical Applications

• Automotive Electronic Control Units (ECUs) — Bulk decoupling and smoothing on power rails where long-term high-temperature endurance and AEC‑Q200 qualification are required.
• Power Supply Filtering — Output filtering and energy buffering for DC‑DC converters and regulator stages that demand high capacitance in a compact SMD package.
• Motor Drive and Power Modules — Local energy storage and ripple reduction on power rails exposed to elevated temperature environments.
• Sensor and Control Electronics — Decoupling for sensors and control circuits in harsh environments, leveraging the wide −55 °C to 125 °C operating range.

Unique Advantages

• Proven High‑Temperature Endurance: 5000 hours at 125 °C provides measurable lifetime performance for designs operating at elevated temperatures.
• Automotive‑Grade Qualification: AEC‑Q200 qualification supports use in automotive-grade modules and systems where qualification is required.
• Compact High Capacitance: 680 µF in a chip-type radial can SMD package reduces board area compared with larger through-hole alternatives while delivering substantial capacitance.
• Robust Ripple Performance: Specified ripple currents (603 mA @120 Hz, 900 mA @10 kHz) help ensure stable operation with switching supplies and variable-frequency loads.
• Wide Temperature Range: −55 °C to 125 °C operation accommodates both cold-start and high-temperature use cases in demanding environments.
• Regulatory Compliance: RoHS compliance aligns with current environmental regulations for restricted substances.
