UCZ1H391MNQ1MS

The UCZ1H391MNQ1MS is a Nichicon aluminum electrolytic chip-type capacitor designed for high-reliability, high-temperature applications. It combines a 390 µF capacitance with a 50 V rating and a chip-format radial can SMD package tailored for automated assembly (carrier-tape compatible).

Engineered for demanding thermal environments, the part is rated from −40°C to +125°C, AEC-Q200 qualified, and RoHS compliant, offering a long endurance life of 3000 h at 125°C and defined ESR and ripple current characteristics for robust power conditioning.

Key Features

• Core Type Chip-type aluminum electrolytic capacitor in a radial can SMD package suitable for surface-mount assembly.
• Temperature Range Rated for −40°C to +125°C to support elevated operating temperatures.
• AEC-Q200 Qualified AEC-Q200 rating for designs requiring automotive-grade component qualification.
• Low-temperature ESR Specification ESR specified after −40°C testing; measured ESR value of 100 mΩ at 100 kHz supports predictable behavior at low temperature.
• Capacitance & Voltage 390 µF capacitance with a 50 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Endurance at High Temperature Specified lifetime of 3000 h at 125°C to provide predictable long-term performance in hot environments.
• Ripple Current Performance Rated ripple current of 650 mA at 120 Hz and 1.3 A at 10 kHz for handling AC stress on power rails.
• Package & Mounting Surface-mount, radial can SMD format compatible with automatic mounting machines fed with carrier tape; physical size L: 1.35 × D: 1.25 cm and recommended land size L: 1.28 × W: 1.28 cm.
• Regulatory Compliance Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronics Power-rail decoupling, smoothing and energy storage in electronic control units and modules that require AEC-Q200 qualified components and operation up to +125°C.
• Power supply filtering DC-link and bulk smoothing in converters and regulators where defined ripple current capability (650 mA @120 Hz, 1.3 A @10 kHz) and 50 V rating are required.
• Industrial control & instrumentation High-temperature industrial electronics that demand long endurance (3000 h at 125°C) and stable ESR across a wide temperature range.

Unique Advantages

• High-temperature endurance: 3000 h at 125°C provides predictable performance margins for prolonged elevated-temperature operation.
• Automotive-grade qualification: AEC-Q200 status enables use in applications requiring that level of component qualification.
• Characterized low-temperature behavior: ESR specified after −40°C testing and 100 mΩ at 100 kHz helps ensure performance across the full −40°C to +125°C range.
• Measurable ripple handling: Rated ripple currents at both low and high frequency (650 mA at 120 Hz and 1.3 A at 10 kHz) support designs with AC stress on filter components.
• Assembly-friendly package: Surface-mount radial can with carrier-tape compatibility simplifies automated placement and board-level integration.
• Regulatory compliance: RoHS conformity supports environmental and regulatory requirements.
