UCZ1J751MNJ1MS

The UCZ1J751MNJ1MS is a high-reliability, chip-type aluminum electrolytic capacitor from Nichicon designed for demanding high-temperature environments. It delivers bulk capacitance (750 µF) at a 63 V rating in a surface-mount, radial can (SMD) package suited for automated tape-and-reel assembly.

Targeted use cases include automotive and other high-temperature power electronics where elevated operating range, robust ripple handling, and long endurance are required. Key value propositions are high temperature capability to +125°C, AEC-Q200 qualification, and low-temperature ESR characterization down to −40°C.

Key Features

• Capacitance and Voltage — 750 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance, providing substantial bulk energy storage for power rails and decoupling.
• High temperature operation — Specified operating temperature range of −40°C to +125°C and endurance rating of 4000 hours at 125°C, supporting sustained use in hot environments.
• Low-temperature ESR characterization — ESR performance specified after a −40°C test, enabling designers to account for impedance behavior across the full temperature range.
• Ripple current capability — Rated ripple current of 1.3 A at 120 Hz and 2.6 A at 10 kHz for effective handling of AC stress on power rails.
• Reliability and qualification — AEC-Q200 Qualified and RoHS compliant, meeting industry reliability expectations and environmental directives.
• Package and assembly — Surface-mount, chip-style radial can (SMD) package designed for automatic mounting with carrier tape; compact size L: 2.15 cm × D: 1.8 cm with recommended land size L: 1.83 cm × W: 1.83 cm.
• Polarized electrolytic — Polarized device suitable for DC bulk and filtering applications where polarity is managed in the circuit design.
• Low ESR — Equivalent series resistance of 68 mΩ measured at 100 kHz for low-loss operation at higher frequencies.

Typical Applications

• Automotive power rails — Bulk decoupling and smoothing for 12 V/48 V vehicle electronics operating to +125°C, leveraging AEC-Q200 qualification and high-temperature endurance.
• DC–DC converters — Input/output bulk capacitor for converters where 63 V rating, 750 µF capacitance, and robust ripple current capability reduce voltage ripple and improve stability.
• Motor controllers and power inverters — Energy storage and ripple suppression in high-temperature power control modules that require high endurance and low ESR.
• Infotainment and electronic control modules — Local energy reservoir for systems that need sustained performance across a wide temperature range.

Unique Advantages

• High-temperature endurance: 4000 hours at 125°C provides predictable long-term performance in elevated-temperature environments.
• Temperature-aware ESR: ESR specification after −40°C testing helps designers optimize low-temperature performance and reliability.
• Strong ripple handling: Dual ripple ratings (1.3 A at 120 Hz, 2.6 A at 10 kHz) enable use across a range of switching and line-frequency conditions.
• AEC-Q200 qualified: Meets the qualification standard referenced in the product data for demanding reliability applications.
• Assembly-ready SMD package: Chip-style radial can suitable for automatic mounting with carrier tape streamlines production and reduces assembly complexity.
• Regulatory compliance: RoHS compliant to relevant directives, supporting environmental and regulatory requirements.
