UCZ1V142MNS1MS

The UCZ1V142MNS1MS is a chip-type aluminum electrolytic capacitor designed for surface-mount assembly and high-temperature operation. With a rated capacitance of 1.4 mF at 35 V and an operating range from -40 °C to 125 °C, it addresses demanding thermal environments while supporting automated production.

Engineered for reliability, this part includes a low-temperature ESR specification after -40 °C testing, AEC-Q200 qualification, and RoHS compliance—making it suitable for designs that require verified performance across temperature extremes and automated pick-and-place mounting.

Key Features

• Core Performance  1.4 mF capacitance at 35 V provides bulk energy storage for power smoothing and decoupling in compact SMD form.
• Temperature & Reliability  Rated for -40 °C to 125 °C operation with an endurance rating of 3500 hours at 125 °C, enabling sustained performance at elevated temperatures.
• Low-temperature ESR Spec  Includes an ESR specification verified after -40 °C testing to ensure predictable impedance behavior in cold environments.
• ESR & Ripple Handling  Specified ESR of 45 mΩ at 100 kHz, with ripple current capability of 1.3 A at 120 Hz and 2.6 A at 10 kHz, supporting both low- and high-frequency ripple conditions.
• Surface-mount Packaging  Radial, can-style SMD package designed for automatic mounting from carrier tape, compatible with standard SMT assembly workflows.
• Industry Qualification & Compliance  AEC-Q200 qualified and RoHS compliant for designs that require recognized reliability and environmental conformance.

Typical Applications

• Automotive electronics  AEC-Q200 qualification and 125 °C rating make this capacitor appropriate for electronic control modules and other vehicle systems that operate in elevated temperatures.
• High-temperature power circuits  The combination of high temperature endurance and defined ESR at low temperature supports power smoothing and decoupling where thermal stability is required.
• Automated assembly lines  Designed for carrier-tape feeding and surface-mount assembly, simplifying integration into high-volume manufacturing.

Unique Advantages

• Validated high-temperature endurance:  3500 hours at 125 °C provides a measurable reliability metric for long-term operation in hot environments.
• Low-temperature performance assurance:  ESR specification after -40 °C testing ensures predictable behavior across the full -40 °C to 125 °C range.
• High ripple capability:  Specified ripple currents at both low (120 Hz) and high (10 kHz) frequencies allow designers to size capacitors based on actual ripple conditions.
• Automated assembly ready:  Carrier-tape compatibility and SMD can packaging reduce assembly friction and support scalable production.
• Industry-grade qualification:  AEC-Q200 rating and RoHS compliance support use in regulated applications with environmental and reliability requirements.
