UCM1K561MNS1MS

The UCM1K561MNS1MS is a surface-mount aluminum electrolytic capacitor in the Nichicon UCM series. It delivers 560 µF capacitance at an 80 V rated voltage in a compact φ16 × 21.5 mm can-style SMD package.

Engineered for demanding environments, this part combines a wide operating temperature range (−55°C to +105°C), AEC-Q200 qualification, and vibration resistance, with a 5000-hour endurance at 105°C for reliable long-term use.

Key Features

• Capacitance and Voltage — 560 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance for high-voltage smoothing and energy storage needs.
• Low Loss Characteristics — Tangent of loss angle (tanδ) of 0.08 measured at 20°C, 120 Hz, 80 V, supporting efficient performance in AC ripple environments.
• Ripple Current Handling — Low-frequency ripple current 1.02 A (120 Hz) and high-frequency ripple current 2.04 A (10 kHz) for robust ripple attenuation across a range of frequencies.
• Leakage Current — Specified leakage current of 448 µA after rated voltage is applied, enabling predictable standby and quiescent behavior.
• Thermal and Endurance — Rated operating temperature −55°C to +105°C with a life/endurance rating of 5000 hours at 105°C.
• Package and Assembly — Surface-mount radial can (SMD) in embossed carrier taping for automated placement; surface-mount land size L: 1.63 × W: 1.63 cm provided for PCB layout.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant; vibration resistant for mechanically demanding applications.

Typical Applications

• Automotive power systems — AEC-Q200 qualification, 80 V rating and wide temperature range support use in automotive electrical modules and power distribution systems.
• High-voltage DC bus filtering — 560 µF capacitance and multi-frequency ripple current ratings make the part suitable for DC bus smoothing in high-voltage circuits.
• Power electronics modules — Long endurance at 105°C and vibration resistance suit power conversion and control modules where thermal and mechanical durability are required.

Unique Advantages

• High-voltage capability: 80 V rated voltage allows use in higher-voltage systems where lower-voltage capacitors are insufficient.
• Proven endurance at elevated temperature: 5000 hours at 105°C provides predictable aging characteristics for long-life designs.
• Broad ripple performance: Specified low- and high-frequency ripple currents support filtering across DC and switching frequencies.
• Automotive-grade reliability: AEC-Q200 qualification and vibration resistance address automotive qualification and mechanical robustness needs.
• SMD-ready packaging: Embossed carrier taping and a compact φ16 × 21.5 mm can simplify automated assembly and PCB footprint planning.
• Regulatory compliance: RoHS compliant to support environmental and regulatory requirements.
