UCZ1E122MNJ1MS

The UCZ1E122MNJ1MS is a chip-type aluminum electrolytic capacitor from Nichicon's UCZ series designed for high-temperature operation up to +125°C. It combines 1.2 mF capacitance at a 25 V rating with a compact surface-mount radial can package suitable for automated carrier-tape assembly.

Engineered for demanding environments, this part offers low ESR performance, defined ripple-current capability, AEC-Q200 qualification, and RoHS compliance—making it suited for applications that require reliable capacitance, temperature endurance, and automated PCB assembly.

Key Features

• Core Electrical 1.2 mF nominal capacitance at 25 V with ±20% tolerance; polarized aluminum electrolytic construction for bulk energy storage and decoupling.
• Low ESR Performance Specified equivalent series resistance of 47 mΩ at 100 kHz; ESR is additionally specified following the −40°C test to ensure low-temperature performance stability.
• Ripple Current Capability Rated ripple current of 850 mA at 120 Hz and 1.7 A at 10 kHz, providing thermal and electrical handling for AC and switching environments.
• High-Temperature Endurance Rated for operation from −40°C to +125°C with a specified lifetime of 3500 hours at 125°C under rated voltage.
• Package and Mounting Surface-mount radial can (SMD) with overall size L: 1.65 × D: 1.6 cm and recommended land size L: 1.63 × W: 1.63 cm; compatible with automatic mounting machines fed by carrier tape.
• Reliability & Compliance AEC-Q200 qualified and RoHS compliant, aligning the part with quality and environmental directives for demanding product designs.

Typical Applications

• Automotive electronics — Bulk filtering and decoupling in control modules and power subsystems where AEC-Q200 qualification and +125°C operation are required.
• High-temperature electronics — Energy storage and smoothing in systems that must operate reliably across −40°C to +125°C ambient ranges.
• Automated surface-mount assemblies — Designed for carrier-tape feed and placement in high-volume PCB assembly for power supply and filtering functions.

Unique Advantages

• Defined low-temperature ESR ESR specified after −40°C testing ensures predictable performance across temperature extremes.
• High ripple handling Dual ripple-current specifications (120 Hz and 10 kHz) provide clear guidance for both low- and high-frequency applications.
• Long high-temperature life 3500 hours endurance at 125°C offers a measurable reliability baseline for elevated-temperature deployments.
• Automated assembly ready Carrier-tape compatibility and SMD radial-can packaging streamline high-volume PCB integration.
• Industry qualifications AEC-Q200 qualification and RoHS compliance support use in regulated and quality-sensitive designs.
