UCX1V681MNS1MS

The UCX1V681MNS1MS is a chip‑type aluminum electrolytic capacitor designed for high‑temperature applications, rated for operation up to +135°C. It provides 680 µF capacitance at 35 V in a compact surface‑mount can suitable for automated, tape‑fed assembly.

Engineered for reliability in demanding environments, this part couples high capacitance and defined ESR performance with AEC‑Q200 qualification and RoHS compliance, making it appropriate for automotive and other high‑temperature electronics designs.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance for bulk energy storage and smoothing on power rails.
• High‑Temperature Operation — Rated operating temperature range −40°C to +135°C to support circuits exposed to elevated ambient conditions.
• Reliability & Qualification — AEC‑Q200 qualified and RoHS compliant, with endurance specified for 2000 hours at 135°C to demonstrate long‑term performance under heat stress.
• ESR Performance — Equivalent series resistance specified at 70 mΩ (measured at 100 kHz); the datasheet includes ESR specification after the −40°C test to characterize low‑temperature behavior.
• Ripple Current Ratings — Defined ripple handling: 375 mA at 120 Hz (low frequency) and 750 mA at 10 kHz (high frequency), useful for filtering and converter outputs.
• Surface‑Mount Package — Chip‑type radial can in an SMD form factor compatible with carrier‑tape automated pick‑and‑place assembly; recommended land size L: 1.28 × W: 1.28 cm.
• Endurance & Solder Heat Resistance — Endurance limits: capacitance change within ±30% after 2000 h at 135°C; meets soldering heat resistance procedures described in the datasheet.

Typical Applications

• Automotive electronics — Bulk decoupling and smoothing for ECUs and power modules where AEC‑Q200 qualification and high‑temperature capability are required.
• DC‑DC converters and power supplies — Output filtering and energy storage in converters operating at elevated temperatures, leveraging defined ripple current and ESR specs.
• Industrial power systems — High‑temperature environments such as power control units and motor drives that need durable, tape‑fed SMD capacitors for automated assembly.

Unique Advantages

• High‑temperature endurance: Specified for 2000 hours at 135°C, providing a quantifiable reliability metric for designs exposed to sustained heat.
• AEC‑Q200 qualification: Enables use in automotive and similarly demanding systems that require industry‑level component qualification.
• Characterized low‑temperature ESR: ESR is specified (70 mΩ at 100 kHz) with additional ESR characterization after −40°C testing, aiding designers concerned with cold‑start and wide‑temperature performance.
• Automated assembly friendly: Carrier‑tape compatibility and an SMD can package streamline high‑volume placement and reduce assembly complexity.
• Defined ripple handling: Distinct ripple current ratings at 120 Hz and 10 kHz give predictable thermal and filtering behavior across common power frequencies.
• RoHS compliant: Meets regulatory restrictions on hazardous substances for broad market acceptance.
