UCZ1H122MNQ1MS

The UCZ1H122MNQ1MS is a high-reliability aluminum electrolytic, chip-type capacitor designed for demanding temperature environments. It combines a 1.2 mF capacitance with a 50 V rating in a surface-mount radial-can package suited for automated assembly.

Engineered for applications requiring low-temperature ESR behavior and extended endurance at elevated temperatures, this part supports operation from −40 °C to +125 °C, is RoHS compliant and AEC‑Q200 qualified.

Key Features

• Capacitance & Voltage — Rated capacitance of 1.2 mF at 50 V, with tolerance −20% to +20%, providing bulk capacitance in a compact chip form.
• Wide Temperature Range & High-Temperature Endurance — Specified operating range −40 °C to +125 °C and endurance rated to 4000 hours at 125 °C.
• Low-Temperature ESR Specification — ESR characterized including added specification after −40 °C testing, delivering predictable performance in low-temperature conditions.
• High-Frequency & Ripple Performance — 38 mΩ ESR measured at 100 kHz; ripple current ratings of 1.45 A at 120 Hz and 2.9 A at 100 kHz support dynamic and high-frequency applications.
• Surface-Mount, Tape-Feedable Package — Radial can, SMD package type designed for automatic mounting machines fed with carrier tape for streamlined assembly.
• Qualification & Compliance — AEC‑Q200 qualification and RoHS (2011/65/EU, (EU)2015/863) compliance for regulated and reliability-sensitive designs.

Typical Applications

• Automotive Electronics — Intended for automotive systems that require AEC‑Q200 qualification and operation across −40 °C to +125 °C.
• High‑Temperature Power Electronics — Suited to designs requiring verified endurance at +125 °C (4000 h) and stable ESR behavior after low-temperature testing.
• Automated Surface‑Mount Assembly — Carrier-tape compatible SMD radial-can package for high-volume, automated placement workflows.

Unique Advantages

• Proven High‑Temperature Endurance — Rated for 4000 hours at 125 °C, enabling longer service life in elevated-temperature environments.
• Low-Temperature ESR Characterization — Includes ESR specification after −40 °C testing, providing designers measurable low-temperature performance.
• High Ripple Current Capacity — Specified ripple current values at both low and high frequencies reduce uncertainty when designing for dynamic loads.
• Surface-Mount, Tape-Feed Ready — Package and carrier-tape compatibility support efficient automated board assembly and throughput.
• Compliance and Qualification — AEC‑Q200 qualification and RoHS compliance support regulated and reliability-focused product programs.
