UCZ1E332MNJ1MS

The UCZ1E332MNJ1MS is a chip-type aluminum electrolytic capacitor designed for high-temperature, high-reliability applications. It delivers 3.3 mF capacitance at 25 V in a surface-mount radial can (SMD) package and is specified for continuous operation from -40°C to +125°C.

Targeted at demanding electronics and automotive systems, this part combines low ESR performance, AEC-Q200 qualification, and carrier-tape compatibility for automated PCB assembly.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 μF) rated at 25 V with ±20% tolerance, providing bulk energy storage for power rails and decoupling.
• High-temperature operation — Specified for -40°C to +125°C continuous use and endurance tested for 4000 hours at 125°C.
• Low ESR and ripple handling — ESR of 32 mΩ measured at 100 kHz; ripple current capability of 1.625 A at 120 Hz and 3.25 A at 10 kHz.
• Reliability & qualification — AEC-Q200 qualified for applications requiring recognized automotive-grade component qualification.
• Surface-mount, production-ready package — Radial can SMD construction, applicable to automatic mounting machines fed with carrier tape; recommended PCB land size 1.83 × 1.83 cm.
• Polarized and RoHS compliant — Polarized aluminum electrolytic construction and conformant with RoHS (2011/65/EU, (EU)2015/863).
• Performance verified at low temperature — Includes an ESR specification measured after the -40°C test to confirm low-temperature behavior.

Typical Applications

• Automotive electronic modules — AEC-Q200 qualification and +125°C endurance make this part suitable for vehicle electronics where elevated ambient temperatures are expected.
• Power conversion and regulation — High capacitance with low ESR and specified ripple currents supports DC–DC converters and power rail smoothing in compact designs.
• High-temperature industrial controls — Long-life rating at 125°C (4000 h) and stable low-temperature ESR support reliable operation in harsh thermal environments.
• Automated surface-mount assembly — Carrier-tape compatible SMD radial-can package streamlines high-volume PCB assembly processes.

Unique Advantages

• High energy density in SMD format: 3.3 mF at 25 V provides significant bulk capacitance while remaining compatible with automated surface-mount processes.
• Thermal robustness: Qualified for continuous operation to +125°C with 4000-hour endurance at that temperature, reducing field-failure risk in hot environments.
• Measurable low-temperature performance: ESR specified after -40°C testing, enabling designers to account for low-temperature impedance in their power budgets.
• Designed for real-world ripple: Explicit ripple current ratings at 120 Hz and 10 kHz let engineers size capacitors to handle both low- and high-frequency ripple content.
• Automotive-grade qualification: AEC-Q200 status supports use in safety- and reliability-focused systems where recognized component qualification is required.
• Assembly-friendly packaging: Carrier-tape compatibility and standardized PCB land recommendations simplify pick-and-place integration.
