UCZ1H122MNJ1MS

The UCZ1H122MNJ1MS from Nichicon is a chip-type aluminum electrolytic capacitor engineered for high-reliability applications. It delivers 1.2 mF capacitance at a 50 V rating in a compact surface-mount can suitable for automated placement.

Designed for extended high-temperature operation (–40 °C to +125 °C) and AEC‑Q200 qualification, this part is targeted at systems that require long life and stable ESR/ripple performance across a wide temperature range.

Key Features

• Capacitance & Voltage — 1.2 mF rated capacitance at 50 V provides bulk energy storage for power supply smoothing and decoupling in compact SMD form.
• High‑Temperature Endurance — Rated for operation from −40 °C to +125 °C with a specified lifetime of 4000 hours at 125 °C.
• Low‑Temperature ESR Specification — ESR characterized after −40 °C testing for verified low‑temperature performance; specified ESR is 38 mΩ at 100 kHz.
• Ripple Handling — Rated ripple currents of 1.45 A at 120 Hz and 2.9 A at 10 kHz support transient and AC ripple suppression in power circuits.
• Surface‑Mount Can Package — Radial, can-style SMD package designed for automatic mounting machines fed with carrier tape; surface mount land size L: 1.83 × W: 1.83 cm.
• Automotive Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), suitable for regulated environments.

Typical Applications

• Automotive Power Electronics — Bulk filtering and decoupling in modules that require AEC‑Q200 qualified components and stable operation up to +125 °C.
• High‑Temperature Electronics — Energy storage and ripple suppression in systems operating in elevated ambient temperatures where long endurance is required.
• Automated Surface‑Mount Production — Designed for carrier‑tape fed placement on automated assembly lines to streamline volume manufacturing.

Unique Advantages

• Extended high‑temperature lifetime: 4000 hours at 125 °C provides predictable endurance for designs exposed to sustained elevated temperatures.
• Verified low‑temperature ESR: ESR specification includes post −40 °C test data, enabling confident use across wide temperature swings.
• High ripple capacity: Specified ripple currents at both low and high frequencies (1.45 A at 120 Hz, 2.9 A at 10 kHz) support demanding power-management tasks.
• Automotive‑grade qualification: AEC‑Q200 rating and RoHS compliance simplify selection for regulated automotive and industrial projects.
• Surface‑mount, tape‑feedable package: Can-style SMD form factor and defined land pattern (L: 1.83 × W: 1.83 cm) support reliable automated placement and PCB integration.
• Compact footprint: Physical dimensions L: 2.15 × D: 1.8 cm balance capacitance and space savings for dense board layouts.
