UWD1A681MCL1GS

The UWD1A681MCL1GS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount use on high-density PCBs. It delivers 680 µF at 10 V with a low impedance of 90 mΩ and is polarized for standard electrolytic capacitor applications.

Engineered for robust thermal and assembly environments, this part supports 260°C peak reflow soldering, is AEC‑Q200 qualified, RoHS compliant, and rated for operation from -55°C to +105°C—making it suited to demanding automotive and industrial surface-mount designs.

Key Features

• Electrical Performance — 680 µF rated capacitance at 10 V with ±20% tolerance and a low impedance of 90 mΩ for effective energy storage and filtering.
• Ripple Handling — Specified ripple current of 335 mA at 120 Hz and 670 mA at 10 kHz to support smoothing and decoupling in power circuits.
• Thermal and Endurance — Operating range −55°C to +105°C and a lifetime rating of 5000 hours at 105°C for long-term stability under elevated temperature conditions.
• High‑temperature Reflow Compatibility — Corresponds with 260°C peak reflow soldering (recommended 260°C peak for 5 seconds; 230°C over 60 seconds for two cycles), enabling reliable surface-mount assembly workflows.
• Surface-mount Package — Chip-type, radial can SMD package designed for automatic mounting with carrier tape on high-density PCBs.
• Industry Compliance — AEC‑Q200 qualified and compliant to the RoHS directive (2011/65/EU, (EU)2015/863) for regulated applications.

Typical Applications

• Automotive electronics — AEC‑Q200 qualification and −55°C to +105°C rating make this capacitor suitable for automotive control modules and other vehicle electronics requiring board-level surface-mount components.
• High-density surface-mount power modules — Chip-type SMD format and carrier-tape compatibility enable automated placement on densely populated PCBs.
• Power-supply decoupling and smoothing — 680 µF capacitance with low impedance and specified ripple current values supports bulk decoupling and smoothing in DC/DC converters and power rails.

Unique Advantages

• Low impedance at rated voltage — 90 mΩ impedance helps reduce voltage ripple and improve transient response in power systems.
• Designed for automated SMD assembly — Chip-type can and carrier-tape compatibility allow use with automatic mounting machines for high-volume production.
• High-temperature reflow resilience — Compatible with 260°C peak reflow profiles for modern lead-free assembly processes.
• Extended high-temperature life — 5000 hours at 105°C provides predictable endurance for sustained elevated-temperature operation.
• Regulatory and reliability credentials — RoHS compliance and AEC‑Q200 qualification support regulated and reliability-focused program requirements.
