UCX1V681MNJ1MS

The UCX1V681MNJ1MS is a chip-type aluminum electrolytic capacitor from Nichicon's UCX series, optimized for high-temperature operation up to +135°C. It is a surface-mount, radial can SMD device designed for automated assembly (carrier tape compatible) and applications that demand robust capacitance, controlled ESR, and long-term endurance.

Targeted for demanding electronics including automotive-grade systems, the part combines 680 µF capacitance at 35 V with an AEC-Q200 qualification and RoHS compliance, delivering reliable decoupling and energy storage where elevated temperatures and durability are required.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance rated for 35 V, with ±20% tolerance (measured at 120 Hz, 20°C).
• High-temperature rating — Rated operating temperature range from -40°C to +135°C, with endurance specified for 2000 hours at 135°C.
• Automotive qualification — AEC-Q200 Qualified, supporting use in automotive electronic modules and other applications requiring industry-recognized reliability.
• Low-temperature ESR characterization — ESR specification included after testing at -40°C, ensuring specified ESR behavior across temperature extremes (70 mΩ at 100 kHz).
• Durability & endurance — Endurance limits: capacitance change within ±30% after 2000 hours at 135°C; tan δ and leakage current limits defined by the datasheet.
• Ripple current capability — Rated ripple current of 375 mA at 120 Hz and 750 mA at 10 kHz for practical power-supply filtering under varying frequencies.
• Surface-mount, assembly-ready — Chip-type radial can SMD package compatible with automatic mounting machines fed by carrier tape; compact footprint with size L: 1.35 × D: 1.25 cm and recommended land size 1.28 × 1.28 cm.
• Compliance — RoHS compliant to (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronic modules — Bulk energy storage and smoothing in control modules where AEC-Q200 qualification and +135°C capability are required.
• Power-supply filtering — Input/output filtering and decoupling for DC–DC converters and regulators operating across wide temperature ranges.
• High-temperature electronics — Energy buffering in systems subjected to sustained elevated ambient temperatures, benefiting from the 2000-hour endurance at 135°C.

Unique Advantages

• High-temperature reliability: Rated to +135°C with endurance data, enabling extended operation in hot environments.
• Automotive-grade qualification: AEC-Q200 status provides traceable qualification for automotive and similarly demanding applications.
• Temperature-aware ESR specification: ESR characterized following -40°C testing and specified at 100 kHz (70 mΩ), supporting predictable performance across thermal extremes.
• Assembly-friendly SMD form factor: Chip-type radial can designed for carrier-tape automated mounting to simplify production and reduce board-level assembly time.
• Practical ripple handling: Defined ripple current ratings at both low and high frequencies (375 mA at 120 Hz, 750 mA at 10 kHz) to match real-world power supply conditions.
• Regulatory compliance: RoHS conformity supports use in regulated product designs.
