UYA1J431MNJ1MS

The UYA1J431MNJ1MS is a chip-type aluminum electrolytic capacitor designed for surface-mount applications. It delivers 430 µF at a 63 V rating in a compact radial can SMD package and is suitable for automotive and other high-temperature electronic assemblies.

Key value propositions include extended high-temperature life (5,000 hours at +125°C), AEC-Q200 qualification for demanding environments, and compatibility with automated carrier-tape mounting for high-volume assembly.

Key Features

• Capacitance & Voltage: 430 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance, providing high capacitance in a chip-style SMD package.
• High-temperature performance: Rated for operation from −40°C to +125°C with endurance specified at 5,000 hours at +125°C, enabling use in elevated-temperature environments.
• Reliability & Qualification: AEC-Q200 qualified and RoHS compliant, with endurance and shelf-life requirements defined in the datasheet.
• Ripple current capability: Specified ripple current of 465 mA at 120 Hz and 930 mA at 10 kHz to support dynamic load conditions.
• Surface-mount, automated assembly ready: Chip-type radial can SMD package designed for automatic mounting machines fed with carrier tape; surface mount land size L: 1.63 × W: 1.63 cm.
• Soldering and leak performance: Meets resistance-to-soldering-heat criteria (hot plate at 250°C for 30 s) and leakage current limits per datasheet definitions.

Typical Applications

• Automotive electronics — AEC-Q200 qualification and 5,000-hour life at +125°C make this capacitor suitable for control modules and subsystems that require high-temperature endurance.
• High-temperature PCB assemblies — Operating range to +125°C and defined resistance to soldering heat support assemblies exposed to elevated processing and ambient temperatures.
• Automated SMT production — Carrier-tape compatible chip package simplifies pick-and-place processing for high-volume manufacturing.

Unique Advantages

• Extended high-temperature lifetime: 5,000 hours at +125°C provides predictable long-term behavior in hot environments.
• Automotive-grade qualification: AEC-Q200 qualification supports use in designs that require documented component-level reliability.
• High capacitance in a compact SMD form: 430 µF at 63 V delivers significant energy storage while maintaining a chip-type surface-mount footprint.
• Assembly-friendly packaging: Designed for carrier-tape feeding to support automated mounting and efficient manufacturing flow.
• Defined ripple handling: Specified ripple current ratings at 120 Hz and 10 kHz help designers account for AC stress in power circuits.
• RoHS compliant: Meets environmental directive requirements for restricted substances.
