UCD2A101MNJ1MS

The UCD2A101MNJ1MS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount assembly on high-density PCBs. It delivers 100 μF capacitance at a 100 V rating with automotive-oriented qualifications and high-temperature endurance for demanding electronic power circuits.

Key Features

• Chip-type, low-impedance construction Designed for SMD use to minimize ESR and support tight board layouts; intended for automatic mounting from embossed carrier tape.
• Electrical characteristics 100 μF capacitance with tolerance −20% to 20% and a rated voltage of 100 V; tanδ (DF) of 0.07 measured at 20°C, 120 Hz.
• Ripple handling Specified ripple currents of 396.5 mA at 120 Hz and 793 mA at 10 kHz support both low- and high-frequency decoupling tasks.
• Leakage and polarization Polarized construction with measured leakage current of 100 μA.
• High-temperature endurance Rated operating temperature range −55°C to +105°C with a lifetime/endurance of 5000 hours at 105°C.
• Package and mounting Surface-mount radial can (SMD) package, size φ16 × 16.5L (L: 1.65 cm × D: 1.6 cm) with surface-mount land size L: 1.63 × W: 1.63 cm and embossed carrier taping for automated assembly.
• Compliance and qualification RoHS compliant and AEC-Q200 qualified.

Typical Applications

• Automotive power modules — Bulk capacitance and ripple suppression on high-voltage automotive rails where 100 V rating and high-temperature endurance are required.
• On-board power supplies — Decoupling and energy buffering in compact, surface-mount power supply designs that demand low impedance and automated placement.
• High-density PCBs — Surface-mount radial can construction and embossed carrier taping enable placement in space-constrained assemblies and high-volume production.

Unique Advantages

• High-voltage capability: 100 V rating enables use on elevated DC rails without stacking components.
• Low-loss performance: tanδ of 0.07 at 20°C/120 Hz supports efficient energy transfer and reduced heating in AC/ripple environments.
• Robust ripple tolerance: Separate low- and high-frequency ripple current ratings (396.5 mA at 120 Hz, 793 mA at 10 kHz) provide predictable behavior across frequency ranges.
• Automotive-grade qualification: AEC-Q200 rating and a −55°C to +105°C operating range address the reliability expectations of vehicle electronics.
• Long-term thermal endurance: 5000 hours at 105°C supports long life in elevated-temperature applications.
• Production-ready packaging: Embossed carrier taping and SMD radial can packaging streamline automated assembly and reduce BOM handling.
