UCX1E122MNS1MS

The UCX1E122MNS1MS is a chip-type aluminum electrolytic capacitor designed for high-temperature operation up to +135°C. It provides 1.2 mF capacitance at 25 V in a surface-mount radial can package tailored for automated assembly with carrier tape.

Engineered for demanding environments, this AEC-Q200‑qualified, RoHS‑compliant capacitor targets automotive and other high-temperature electronics where low ESR, robust ripple handling, and long-term reliability are required.

Key Features

• Temperature & Reliability: Rated for operation from −40°C to +135°C with an endurance specification of 2000 hours at 135°C.
• Capacitance & Tolerance: 1.2 mF nominal capacitance at 25 V with ±20% tolerance for predictable energy storage.
• Low ESR: Equivalent series resistance of 50 mΩ measured at 100 kHz, supporting efficient high-frequency performance.
• Ripple Current Capability: Handles 600 mA at 120 Hz and 1.2 A at 10 kHz, enabling effective filtering and smoothing in power circuits.
• Mounting & Package: Surface-mount radial can (chip type) compatible with automatic mounting machines fed by carrier tape; compact dimensions L: 1.65 × D: 1.6 cm with recommended land size L: 1.63 × W: 1.63 cm.
• Automotive Qualification & Compliance: AEC‑Q200 qualified and RoHS compliant, supporting use in regulated automotive electronics applications.

Typical Applications

• Automotive electronic modules — Suitable for power rail smoothing and decoupling in ECUs and other vehicle electronics where AEC‑Q200 qualification and high-temperature endurance are required.
• High-temperature power management — Used in power supply modules and DC–DC converters operating in elevated ambient temperatures up to +135°C.
• Compact SMD assemblies — Designed for automated placement on densely populated PCBs where a small radial can SMD capacitor with reliable ripple performance is needed.

Unique Advantages

• High-temperature endurance: 2000 hours at 135°C provides predictable lifetime behavior in hot environments.
• Automotive-ready qualification: AEC‑Q200 qualification enables use in automotive electronics with documented reliability standards.
• Low high-frequency ESR: 50 mΩ at 100 kHz reduces power loss and improves stability in fast-switching power circuits.
• Robust ripple handling: Rated ripple currents of 600 mA (120 Hz) and 1.2 A (10 kHz) support both low- and high-frequency filtering needs.
• SMD-compatible package: Chip-type radial can and carrier-tape compatibility simplify automated assembly and footprint integration.
