UCZ1V681MNQ1MS

The UCZ1V681MNQ1MS is a surface-mount, chip-type aluminum electrolytic capacitor designed for high-reliability applications. It offers 680 µF capacitance at a 35 V rating with a temperature range of -40°C to 125°C, making it suited for demanding thermal environments.

Key strengths include low ESR (60 mΩ at 20°C/100 kHz), robust ripple handling, AEC-Q200 qualification, and packaging compatible with automatic placement for high-volume assembly.

Key Features

• Electrical Performance  680 µF capacitance with ±20% tolerance (measured at 20°C, 120 Hz) and a rated voltage of 35 V for medium-voltage power rails.
• Low Loss / ESR  ESR of 60 mΩ at 20°C/100 kHz supports efficient high-frequency operation and reduced power dissipation.
• Ripple Current Capability  Low-frequency ripple current of 850 mA (120 Hz) and high-frequency ripple current of 1.7 A (10 kHz) for effective smoothing and decoupling.
• High-Temperature Endurance  Endurance rating of 3000 hours at 125°C, enabling sustained operation in elevated-temperature applications.
• Leakage & Loss Characteristics  Leakage current specified at 238 µA; tangent of loss angle (tan δ) specified at 0.16 (measured at 20°C, 120 Hz) for the 35 V rating.
• Package & Mounting  Surface-mount can package (φ12.5 × 13.5L / 1.25 × 1.35 cm) supplied on embossed carrier tape for automatic mounting machines.
• Quality & Compliance  AEC-Q200 qualified and RoHS compliant for regulated environments and automotive-grade reliability expectations.

Typical Applications

• Automotive Electronic Modules  AEC-Q200 qualification and operation to 125°C make this capacitor suitable for control modules and power electronics in automotive systems.
• 35 V Power Supplies  Provides bulk energy storage and smoothing on 35 V rails where 680 µF capacitance and robust ripple handling are required.
• High-Temperature Electronics  Designed for systems that require long-term operation at elevated temperatures up to 125°C.
• High-Volume SMD Assembly  Embossed carrier taping and SMD can package support automated pick-and-place manufacturing.

Unique Advantages

• High-temperature reliability: Endurance rated 3000 hours at 125°C for sustained performance in hot environments.
• Strong ripple handling: Combined LF and HF ripple current specs (850 mA at 120 Hz, 1.7 A at 10 kHz) reduce voltage ripple and heat buildup in power circuits.
• Low high-frequency ESR: 60 mΩ at 100 kHz lowers losses and improves efficiency in switching and decoupling applications.
• Automotive-grade qualification: AEC-Q200 qualification supports use in automotive electronic assemblies requiring rigorous component screening.
• Assembly-ready packaging: Supplied on embossed carrier tape for compatibility with automatic mounting machines and streamlined production flow.
• Regulatory compliance: RoHS compliance for alignment with environmental regulations.
