UCD1K101MNJ1MS

The UCD1K101MNJ1MS is a surface-mount aluminum electrolytic capacitor in Nichicon’s UCD series, designed as a low-impedance chip-type solution for high-density PCB assemblies. It provides 100 µF capacitance at an 80 V rating with a wide operating temperature range from −55 °C to 105 °C and is AEC-Q200 qualified for demanding applications.

This part targets power filtering, decoupling and energy-storage use cases in automotive and industrial systems where long endurance, low loss and automated placement are important. Key value comes from its low loss (tan δ), controlled leakage, robust ripple handling and tape-and-reel packaging for automated assembly.

Key Features

• Capacitance and Voltage — 100 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Low Impedance / Low Loss — Chip-type, low-impedance construction with a tangent of loss angle (tan δ) of 0.08 measured at 20 °C, 120 Hz, supporting efficient AC performance.
• Ripple Current Capability — Specified low-frequency ripple current of 250 mA at 120 Hz and high-frequency ripple current of 500 mA at 10 kHz, enabling handling of both mains-frequency and switching-frequency ripple.
• Leakage Current — Leakage current specified at 80 µA for predictable standby and low-loss performance.
• Thermal and Endurance Performance — Operating temperature from −55 °C to 105 °C with an endurance rating of 5000 hours at 105 °C.
• Package and Mounting — Radial can SMD package (φ12.5 × 13.5 mm / L: 13.5 mm, D: 12.5 mm) designed for surface-mount placement with embossed carrier taping for automated assembly.
• Polarized Aluminum Electrolyte — Polar construction suitable for DC smoothing and power rail decoupling.
• Qualification and Compliance — AEC-Q200 qualified and RoHS compliant for regulated environments and automotive applications.

Typical Applications

• Automotive power modules — Bulk smoothing and decoupling on DC rails and power conversion stages where AEC-Q200 qualification and high-temperature endurance are required.
• DC-DC converters — Input/output filtering and energy buffering for converters that require 80 V rating and robust ripple handling.
• Industrial power electronics — Power supply filtering and transient absorption in motor drives, controllers and industrial converters operating across a wide temperature range.
• High-density PCB assemblies — Surface-mount radial-can form factor and embossed carrier taping enable automated placement in compact, high-density designs.

Unique Advantages

• High voltage capability: 80 V rating supports higher-voltage DC rails without series stacking.
• Low-loss performance: tan δ = 0.08 at 120 Hz (20 °C) reduces dissipative heating and improves AC efficiency.
• Balanced ripple handling: Defined ripple currents at both low and high frequencies (250 mA @120 Hz, 500 mA @10 kHz) for mixed-frequency power systems.
• Long endurance at temperature: 5000 hours at 105 °C provides predictable lifetime in thermally demanding environments.
• Automated assembly ready: Embossed carrier taping and SMD radial-can packaging streamline high-volume manufacturing.
• Automotive-grade qualification: AEC-Q200 rating supports use in vehicle electrics and related systems.
