UCZ1V821MNS1MS

The UCZ1V821MNS1MS is a chip-type aluminum electrolytic capacitor designed for high-temperature environments. It delivers 820 µF capacitance at a 35 V rating in a surface-mount, radial can SMD package suitable for automated assembly.

Targeted at demanding electronics applications, the part combines a wide operating range (−40°C to +125°C), added low-temperature ESR specification, and AEC-Q200 qualification to provide stable performance and reliability where temperature and endurance matter.

Key Features

• Capacitance & Voltage — 820 µF capacitance rated for 35 V, with ±20% tolerance at 120 Hz, 20°C.
• High-temperature operation — Rated for continuous use from −40°C to +125°C, with endurance specified for 3500 hours at 125°C for the applicable case size.
• Low-temperature ESR specification — ESR characterized after the −40°C test and specified as 47 mΩ at 100 kHz, supporting stable impedance in cold conditions.
• Ripple handling — Rated ripple currents of 1.2 A at 120 Hz and 2.4 A at 10 kHz, enabling reliable performance under AC stress.
• Surface-mount, automatic assembly ready — Radial can SMD package designed for carrier-tape feeding and placement on automatic mounting machines; surface-mount land size L: 1.63 × W: 1.63 cm.
• Reliability and standards — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulated and high-reliability applications.
• Endurance and stability — Specified capacitance change and leakage characteristics after endurance and shelf-life tests, plus resistance to soldering heat per the datasheet.

Typical Applications

• Automotive electronics — Suitable for vehicle electronic modules that require components qualified to AEC-Q200 and rated for extended high-temperature operation.
• High-temperature electronics — Use in assemblies and systems that operate continuously near +125°C where thermal endurance is required.
• Automated surface-mount production — Designed for carrier-tape feeding and automatic placement, simplifying high-volume PCB assembly.

Unique Advantages

• High-temperature endurance: Rated operation to +125°C with specified endurance hours at that temperature, enabling sustained performance in hot environments.
• Low-temperature ESR assurance: ESR specified after −40°C testing and measured at 47 mΩ (100 kHz), providing predictable impedance across the temperature range.
• AEC-Q200 qualification: Explicit qualification supports use in regulated and high-reliability designs requiring recognized component standards.
• Automated assembly compatibility: Carrier-tape applicable SMD can and defined land pattern reduce handling complexity and speed production ramp-up.
• Solid ripple performance: Defined ripple current ratings at both low and high frequencies help manage AC stress in power circuits.
• Regulatory compliance: RoHS compliant to 2011/65/EU and (EU)2015/863, simplifying environmental and procurement compliance.
