UCX1H561MNQ1MS

The UCX1H561MNQ1MS is a chip-type aluminum electrolytic capacitor in Nichicon’s UCX series designed for surface-mount assembly and high-temperature operation. With a 560 µF capacitance at 50 V and rated for operation from -40 °C to +135 °C, it targets applications that require high-temperature endurance, surface-mount placement, and controlled ESR behavior across temperature extremes.

Key Features

• Capacitance & Voltage — 560 µF rated capacitance at 50 V with ±20% tolerance, providing stored energy and bulk decoupling capability for power circuits.
• High-Temperature Operation — Specified operating temperature range of -40 °C to +135 °C with endurance tested to 2000 hours at 135 °C, enabling use in elevated-temperature environments.
• ESR & Ripple Performance — Equivalent series resistance specified as 70 mΩ at 100 kHz; ripple current ratings of 500 mA at 120 Hz and 1 A at 10 kHz support dynamic power demands.
• Reliability & Qualification — AEC-Q200 Qualified and compliant with the RoHS directive (2011/65/EU, (EU)2015/863); ESR specification is provided following a -40 °C test to characterize low-temperature behavior.
• Surface-Mount, Tape-Fed Package — Chip-type, radial can SMD intended for automatic mounting machines fed with carrier tape; compact dimensions L: 1.65 × D: 1.6 cm and recommended PCB land size L: 1.63 × W: 1.63 cm.
• Polarized Construction — Polarized aluminum electrolytic design for DC power applications requiring bulk capacitance in a surface-mount form factor.

Typical Applications

• Automotive Electronics — Suitable for electronic modules and power systems where AEC-Q200 qualification and high-temperature endurance are required.
• High-Temperature Electronics — Bulk energy storage and decoupling in designs that must operate reliably up to +135 °C.
• Automated Surface-Mount Production — Designed for use with carrier-tape fed automatic mounting machines to streamline SMT assembly.

Unique Advantages

• High-temperature endurance: 2000 hours rated at 135 °C supports extended operation in elevated-temperature environments.
• Temperature-validated ESR: ESR specification maintained after a -40 °C test provides predictable performance across wide temperature swings.
• Automotive-grade qualification: AEC-Q200 qualification indicates suitability for automotive electronic use cases that require industry-recognized reliability standards.
• Compact SMT can: Chip-type, radial can SMD package with tape-feed compatibility reduces handling steps in automated assembly.
• Clear ripple handling: Rated ripple currents at both low and high frequencies help manage dynamic loads in power electronics.
