UCX1V681MNQ1MS

The UCX1V681MNQ1MS is a Nichicon UCX series chip‑type aluminum electrolytic capacitor in a radial can SMD package, rated 680 µF at 35 V. It is designed for surface‑mount assembly and automatic carrier‑tape feeding for high‑temperature applications.

Engineered for high operating temperatures (−40°C to +135°C) with AEC‑Q200 qualification and RoHS compliance, this capacitor delivers low ESR and defined ripple handling for power decoupling and filtering in demanding electrical environments.

Key Features

• Electrical rating — 680 µF nominal capacitance at 35 V with ±20% tolerance, polarized for bulk energy storage and decoupling.
• High temperature operation — Rated for −40°C to +135°C, suitable for use in elevated ambient conditions.
• Reliability & endurance — Endurance specified as 2000 hours at 135°C; after the endurance test, capacitance change is within ±30% and leakage current meets initial specified values per UCX series specifications.
• Low‑temperature ESR characterization — ESR behavior is specified following −40°C testing, supporting predictable performance across the full temperature range.
• Low ESR & ripple capability — Equivalent series resistance of 70 mΩ (measured at 100 kHz) with ripple current ratings of 375 mA at 120 Hz and 750 mA at 10 kHz for AC stress handling.
• Package & mounting — Surface mount radial can (Chip type) sized L: 1.35 × D: 1.25 cm with recommended land pattern 1.28 × 1.28 cm; compatible with automatic mounting machines using carrier tape.
• Assembly durability — Meets soldering heat resistance tests (hot plate at 250°C for 30 seconds) as specified for the UCX series.
• Qualification & compliance — AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronics — Bulk decoupling and energy buffering for in‑vehicle power systems and electronic control modules where AEC‑Q200 qualification and +135°C capability are required.
• Power conversion / DC‑DC converters — Input/output smoothing and ripple suppression for converters, benefiting from low ESR (70 mΩ) and high ripple current capability.
• Industrial power modules — High‑temperature power systems and control modules that demand long endurance at elevated temperatures (2000 h at 135°C).

Unique Advantages

• High‑temperature durability: Rated to +135°C with a defined 2000‑hour endurance specification, enabling reliable operation in hot environments.
• Predictable low‑temperature performance: ESR is specified after −40°C testing, providing predictable behavior across extreme operating ranges.
• Balanced ripple handling: Dual ripple ratings (120 Hz and 10 kHz) and a 70 mΩ ESR support both low‑ and high‑frequency ripple suppression.
• Automated assembly ready: Designed for carrier‑tape feeding and surface‑mount placement to streamline high‑volume manufacturing.
• Industry qualification: AEC‑Q200 qualification and RoHS compliance support deployment in regulated environments and long‑life programs.
• Compact SMD radial can: Small footprint (L 1.35 × D 1.25 cm) with a standard recommended land size for space‑constrained designs.
