UCX1H122MNQ1MS

The UCX1H122MNQ1MS is a chip-type aluminum electrolytic capacitor designed for high-reliability, high-temperature applications. This surface-mount, polarized capacitor delivers 1.2 mF capacitance at a 50 V rating and is optimized for automated placement from carrier tape.

Built for environments that require extended high-temperature endurance and stable ESR across a wide temperature range, the part is AEC‑Q200 qualified and RoHS compliant, making it suitable for demanding automotive and industrial power electronics.

Key Features

• High temperature rating – Rated for continuous operation from −40 °C to +135 °C with endurance specified at 2000 hours at 135 °C.
• Low-temperature ESR specification – ESR characterized down to −40 °C; equivalent series resistance specified as 40 mΩ at 100 kHz.
• High ripple capability – Supports 950 mA ripple at 120 Hz and 1.9 A ripple at 10 kHz for demanding power-rail smoothing and decoupling.
• Capacitance and tolerance – 1.2 mF nominal capacitance with tolerance −20% / +20% (measured at 120 Hz, 20 °C).
• Automated assembly ready – Chip-type, surface-mount package compatible with carrier tape feeding for automatic mounting machines.
• AEC‑Q200 qualified & RoHS compliant – Series-level AEC‑Q200 qualification and compliance with RoHS (2011/65/EU, (EU)2015/863) for regulated markets.
• Compact SMD can package – Package dimensions L: 2.15 cm × D: 1.8 cm with recommended land size 1.83 cm × 1.83 cm for PCB layout.

Typical Applications

• Automotive power electronics – High-temperature endurance and AEC‑Q200 qualification make this capacitor suitable for power rails and ECU modules exposed to elevated ambient temperatures.
• DC–DC converters and voltage regulation – Low ESR and high ripple current capability support input/output smoothing and transient filtering in power-conversion stages.
• Industrial control and power modules – Robust lifetime at 135 °C and soldering-heat resistance support use in compact, high-reliability industrial electronics.

Unique Advantages

• Proven high-temperature endurance: 2000 hours at 135 °C provides predictable lifetime behavior in elevated-temperature designs.
• Temperature-stable ESR: ESR characterized after −40 °C testing and specified at 40 mΩ (100 kHz) helps ensure stable filtering over wide temperature swings.
• Designed for automated manufacturing: Chip SMD format and carrier-tape compatibility simplify high-volume assembly and reduce placement-related handling.
• High ripple handling: Measured ripple current ratings at both low and high frequencies enable reliable performance across typical power-supply switching and mains-derived ripple conditions.
• Automotive-grade qualification: AEC‑Q200 qualification addresses the reliability expectations of vehicle electronics and related high-reliability markets.
• Regulatory compliance: RoHS compliance supports deployment in regions and products subject to restricted substances requirements.
