The UCZ2A301MNJ1MS is a surface-mount aluminum electrolytic capacitor in Nichicon’s UCZ series engineered for high-temperature operation and automated assembly. It delivers 300 µF at 100 V with a chip-style SMD can package and embossed carrier taping for pick-and-place lines.

Targeted at applications requiring elevated temperature endurance and robust ripple handling, this part combines a wide operating range (−40°C to +125°C), AEC-Q200 qualification, and long-life endurance (4000 hours at 125°C) for reliable performance in demanding environments.

Key Features

• Capacitance and Voltage — 300 µF rated capacitance at 100 V nominal, with tolerance −20% to +20%.
• High-Temperature Operation — Rated for −40°C to +125°C and specified for 4000 hours endurance at 125°C.
• Low Loss (tan δ) — tanδ = 0.10 measured at 20°C, 120 Hz, 100 V, supporting stable performance under AC excitation.
• Low ESR at High Frequency — ESR of 110 mΩ measured at 20°C/100 kHz, enabling effective high-frequency ripple attenuation.
• Ripple Current Capability — Low-frequency ripple current 850 mA (120 Hz) and high-frequency ripple current 1.7 A (100 kHz) for power-conditioning applications.
• Leakage Current — Specified leakage current of 300 µA at rated conditions.
• Package and Mounting — Chip-type SMD can, size φ18 × 21.5 mm (L: 2.15 × D: 1.8 cm), surface-mount land size L: 1.83 × W: 1.83 cm; supplied in embossed carrier taping for automated placement.
• Reliability and Compliance — AEC-Q200 qualified and RoHS compliant; designed for assembly processes including high-temperature soldering.

Typical Applications

• Automotive Electronics — Suitable for electronic modules that require components qualified to AEC-Q200 and operation up to +125°C.
• High-Temperature Electronic Assemblies — Designed for boards and modules needing capacitors specified for extended operation and reliability at elevated temperatures.
• Automated Surface-Mount Production — Embossed carrier taping and chip-type SMD package support high-volume pick-and-place manufacturing.

Unique Advantages

• High Voltage Rating: 100 V nominal rating provides extended headroom for higher-voltage circuitry and energy storage requirements.
