UCZ1J751MNQ1MS

The UCZ1J751MNQ1MS is a chip-type aluminum electrolytic capacitor designed for high-temperature operation up to +125°C. It provides 750 µF capacitance at a 63 V rating in a surface-mount radial can (SMD) format with polarized construction.

Targeted for automotive and other high-reliability electronics, this part combines AEC‑Q200 qualification and RoHS compliance with carrier-tape compatibility for automated assembly. It delivers low ESR and specified ripple current ratings to support power smoothing and decoupling in harsh thermal environments.

Key Features

• Core Electrical 750 µF capacitance with a 63 V rated voltage and ±20% tolerance, providing bulk energy storage for power rails and decoupling applications.
• Temperature & Reliability Rated for operation from −40°C to +125°C with a specified lifetime of 4000 hours at 125°C, supporting prolonged high-temperature use.
• Electrical Performance Low ESR specification of 68 mΩ measured at 100 kHz, plus added ESR data after −40°C testing. Ripple current ratings are 1.3 A at 120 Hz and 2.6 A at 10 kHz.
• Package & Assembly Surface-mount radial can (SMD) package designed for tape-fed automatic mounting machines; recommended land size L 1.83 × W 1.83 cm for PCB layout.
• Compliance & Qualification AEC‑Q200 qualified and compliant with the RoHS directive (2011/65/EU, (EU)2015/863), suitable for regulated, high-reliability designs.
• Mechanical Dimensions Compact component size L: 2.15 × D: 1.8 cm for dense board designs where high capacitance is required in a small footprint.
• Polarized Construction Polarized aluminum electrolytic design for typical DC filtering and energy-storage applications.

Typical Applications

• Automotive electronics — Use in ECUs and power modules where AEC‑Q200 qualification and sustained operation to +125°C are required.
• Power supply filtering — Bulk smoothing and decoupling on DC‑DC converters and power rails, leveraging 750 µF capacitance, low ESR, and rated ripple currents.
• High-temperature industrial electronics — Capacitor choice for boards operating across −40°C to +125°C with long-term stability (4000 h at 125°C).
• Automated PCB assembly — Carrier-tape compatible for efficient pick-and-place mounting in production lines.

Unique Advantages

• AEC‑Q200 qualification: Provides an established reliability baseline for designs targeting automotive and other high-reliability markets.
• High-temperature endurance: Rated for continuous use up to +125°C with a specified 4000-hour lifetime at that temperature for sustained performance under heat stress.
• Low ESR at frequency and temperature extremes: 68 mΩ at 100 kHz and ESR characterization after −40°C testing enable predictable performance in demanding thermal cycles.
• Defined ripple handling: Specified ripple currents (1.3 A at 120 Hz, 2.6 A at 10 kHz) help designers size capacitors for real-world power applications.
• Assembly-ready SMD can: Surface-mount radial can format with carrier-tape compatibility reduces assembly complexity and supports automated manufacturing.
• Regulatory compliance: RoHS conformity ensures compatibility with environmental and product compliance requirements.
