UCZ1V681MNS1MS

The UCZ1V681MNS1MS is a chip-type aluminum electrolytic capacitor designed for high-reliability applications. It delivers 680 µF at 35 V in a compact surface-mount can package and is built for continuous operation across a wide temperature range from -40 °C to +125 °C.

Engineered for automated assembly and demanding thermal environments, this part is AEC‑Q200 qualified and RoHS compliant, offering a combination of high-temperature endurance, low-temperature ESR performance, and measurable ripple-handling capability.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 35 V with ±20% tolerance, suitable for bulk filtering and energy storage in power rails.
• High-Temperature Operation — Rated for operation from -40 °C to +125 °C and specified for 3000 hours at 125 °C, enabling sustained performance in elevated-temperature environments.
• Low-Temperature ESR Specification — ESR specified after -40 °C testing, providing predictable impedance behavior in cold conditions.
• Low ESR & Ripple Capability — Equivalent series resistance of 60 mΩ at 100 kHz plus ripple ratings of 850 mA at 120 Hz and 1.7 A at 10 kHz for robust filtering at both low and high frequencies.
• Surface-Mount, Tape-Feed Compatible — Chip-type radial can SMD package designed for automatic mounting machines fed with carrier tape to streamline high-volume assembly.
• Reliability & Compliance — AEC‑Q200 qualified for reliability-focused designs and compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Footprint — Package dimensions L: 1.35 × D: 1.25 cm with recommended land size L: 1.28 × W: 1.28 cm for space-efficient board layouts.
• Polarized Electrolytic — Polarized design appropriate for DC filtering and energy storage applications that require electrolytic capacitance characteristics.

Typical Applications

• Automotive Electronics — Suited for automotive control modules and power subsystems that require AEC‑Q200-qualified components and reliable operation up to +125 °C.
• Power Supply Filtering — Bulk filtering and smoothing on DC power rails where 680 µF capacitance, low ESR, and defined ripple handling improve voltage stability.
• High-Temperature Industrial Electronics — Used in industrial power assemblies and modules that operate in elevated thermal environments and demand long endurance at +125 °C.

Unique Advantages

• Designed for Elevated Temperatures — Specified endurance of 3000 hours at +125 °C provides confidence for sustained high-temperature operation.
• Predictable Cold-Temperature Performance — ESR characterization after -40 °C testing ensures designers can account for impedance changes in cold conditions.
• Measured Ripple Handling Across Frequencies — Separate ripple ratings at 120 Hz and 10 kHz allow accurate thermal and performance budgeting for both line-frequency and switching-power applications.
• Automated Assembly Ready — Carrier-tape compatibility and SMD can package reduce assembly cycle time and improve throughput in automated production lines.
• Standards and Environmental Compliance — AEC‑Q200 qualification and RoHS compliance support reliability programs and regulatory requirements.
