UCZ1J181MNS1MS

The UCZ1J181MNS1MS is a chip-type aluminum electrolytic capacitor designed for high-temperature operation and automated surface-mount assembly. With a 180 µF capacitance at 63 V rating and a polarized can-style SMD package, it targets designs that require elevated temperature endurance and placement compatibility with carrier-tape fed mounting machines.

Key value comes from a wide operating temperature range (−40°C to +125°C), explicit low-temperature ESR specification, AEC-Q200 qualification, and RoHS compliance—attributes that support reliable performance in demanding environments.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 63 V rated voltage and a tolerance of −20% to +20%.
• High-temperature endurance — Rated for continuous operation from −40°C to +125°C with a specified lifetime of 3000 hours at 125°C.
• Low-temperature ESR specification — ESR is specified with consideration after −40°C testing; equivalent ESR is 200 mΩ at 100 kHz.
• Ripple current capability — Supports 500 mA at 120 Hz (low frequency) and 1 A at 10 kHz (high frequency) for power-handling applications.
• Surface-mount packaging — Chip-type radial can in an SMD-compatible package, sized L: 1.35 × D: 1.25 cm with surface-mount land size L: 1.28 × W: 1.28 cm and suitable for carrier-tape fed automatic mounting machines.
• Polarized design — Polarized aluminum electrolytic configuration for DC applications where polarity is defined.
• Compliance & qualification — AEC-Q200 qualified and RoHS compliant for regulated and automotive-capable designs.

Typical Applications

• Automotive electronics — AEC-Q200 qualification and −40°C to +125°C rating make this capacitor suitable for electronics modules that require automotive-grade components.
• High-temperature systems — Designed for continuous operation at elevated temperatures with a documented 3000-hour endurance at 125°C.
• Automated surface-mount production — Carrier-tape compatibility and SMD can package facilitate pick-and-place assembly in high-volume manufacturing.

Unique Advantages

• Temperature-hardened reliability — Specified endurance at 125°C (3000 hours) provides predictable life under prolonged high-temperature stress.
• Low-temperature performance tracking — ESR specification that accounts for −40°C testing helps designers manage impedance and stability across the full operating range.
• Clear ripple handling specs — Separate ripple current ratings at 120 Hz and 10 kHz allow precise thermal and ripple management for power designs.
• SMD-ready with tape-feed compatibility — Enables efficient automated placement and consistent PCB assembly for volume production.
• Industry qualification and compliance — AEC-Q200 qualification and RoHS compliance support regulated and automotive-focused design requirements.
