UCZ1J391MNS1MS

The UCZ1J391MNS1MS is a chip-type aluminum electrolytic capacitor designed for surface-mount assemblies and automatic placement. It delivers 390 µF at 63 V with polarized operation and is specified for continuous use up to 125°C.

Targeted for demanding thermal environments—including automotive electronics—the device combines extended high-temperature endurance with defined low-temperature ESR behavior, supporting power filtering and decoupling where elevated ambient temperature and robust ripple handling are required.

Key Features

• Chip / Package Chip-type aluminum electrolytic capacitor in a radial, can SMD package suitable for automatic mounting machines fed with carrier tape.
• Temperature Range Rated for operation from −40°C to +125°C, enabling use in high-temperature environments.
• Electrical Characteristics 390 µF nominal capacitance at 63 V with ±20% tolerance; polarized design for DC smoothing and energy storage.
• Low‑temperature ESR Specification ESR specified as 130 mΩ at 100 kHz; the datasheet includes ESR assessment after a −40°C test to characterize low-temperature performance.
• Ripple Current & Frequency Performance Rated ripple current of 950 mA at 120 Hz and 1.9 A at 10 kHz, supporting AC ripple and switching-power applications.
• High-temperature Endurance Specified lifetime of 3500 hours at 125°C, with endurance and leakage limits defined after high-temperature exposure.
• Soldering & Assembly Designed for surface-mount processes with defined resistance to soldering heat; compatible with automated tape-fed placement.
• Qualification & Compliance AEC‑Q200 qualified and RoHS compliant, supporting regulated and high-reliability program requirements.

Typical Applications

• Automotive electronics Use for power smoothing and decoupling in automotive control modules where AEC‑Q200 qualification and +125°C capability are required.
• Power supply filtering Bulk and ripple suppression in high-voltage DC rails up to 63 V, leveraging the part’s ripple current ratings and ESR data.
• High-temperature embedded systems Energy storage and transient support in boards operating across −40°C to +125°C environments.

Unique Advantages

• AEC‑Q200 qualification Provides a documented qualification path for applications that require established automotive-level component screening.
