UCX1V122MNS1MS

The UCX1V122MNS1MS is a chip-type aluminum electrolytic capacitor from Nichicon's UCX series, designed for surface-mount assembly and carrier-tape fed production. It provides 1.2 mF capacitance at a 35 V rating in a compact SMD can-style package.

Engineered for demanding thermal environments, the part is specified for operation from −40 °C to +135 °C, carries AEC-Q200 qualification, and is RoHS compliant. The device includes ESR specification following −40 °C testing and explicit ripple current ratings for both low and high frequency operation.

Key Features

• Capacitance & Voltage — 1.2 mF nominal capacitance, rated for 35 V DC; polarized electrolytic construction.
• Temperature & Endurance — Operating range −40 °C to +135 °C with endurance characterized to 2000 hours at 135 °C (post-test recovery conditions per datasheet).
• Low-temperature ESR Specification — ESR specified after −40 °C testing to ensure defined performance across the temperature range.
• ESR Value — Equivalent Series Resistance: 50 mΩ at 100 kHz.
• Ripple Current Ratings — 700 mA at 120 Hz (low frequency) and 1.4 A at 10 kHz (high frequency) to support dynamic load conditions.
• Package & Mounting — Surface-mount (radial, can - SMD) construction compatible with automatic mounting machines using carrier tape; physical size L: 1.65 × D: 1.8 cm and recommended land size L: 1.83 × W: 1.83 cm.
• Standards & Compliance — AEC-Q200 qualified and RoHS compliant, as noted in product documentation.

Typical Applications

• Automotive electronics — Component selection for modules and subsystems requiring AEC-Q200 qualification and operation in elevated-temperature automotive environments.
• High-temperature electronic assemblies — Use in boards and modules that must operate reliably across −40 °C to +135 °C ambient conditions.
• Automated surface-mount production — Designed for carrier-tape feeding to support pick-and-place assembly and high-volume manufacturing workflows.

Unique Advantages

• High-temperature endurance: Characterized for 2000 hours at 135 °C to support long-term operation in hot environments.
• Defined low-temperature performance: ESR specification added after −40 °C testing provides documented impedance behavior across temperature extremes.
• Clear ripple-current ratings: Published values at 120 Hz and 10 kHz enable engineers to match the capacitor to dynamic load requirements.
• AEC-Q200 qualification: Qualification noted in product data to support use in designs that require automotive-grade component reliability.
• Assembly-ready SMD format: Carrier-tape compatibility and compact can package simplify integration into automated production lines.
• Regulatory compliance: RoHS-compliant construction aligns with regulatory requirements for restricted substances.
