UCD2A101MNQ1MS

The UCD2A101MNQ1MS is a chip-type aluminum electrolytic capacitor designed for surface-mount assembly on high-density PC boards. It provides 100 µF capacitance at a 100 V rating with low impedance characteristics targeted for demanding power decoupling and filtering tasks.

Engineered for elevated operating conditions, the device supports a wide temperature range from −55°C to 105°C, AEC‑Q200 qualification, and is supplied in embossed carrier taping for automated placement.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a rated voltage of 100 V and capacitance tolerance of ±20% (−20%~20%).
• Low Loss / Low Impedance — Tangent of loss angle (tanδ) specified at 0.07 (measured at 20°C, 120 Hz), supporting lower dissipation in AC conditions.
• Ripple Current Performance — Low-frequency ripple current of 396.5 mA (120 Hz) and high-frequency ripple current of 793 mA (10 kHz) for effective smoothing and decoupling under dynamic loads.
• Leakage Current — Specified leakage current of 100 µA, enabling lower standby losses in power systems.
• High-Temperature Endurance — Rated for 5,000 hours at 105°C, providing extended life under elevated ambient temperature stress.
• Surface-Mount Chip Package — Chip-type, radial can SMD package (Size: φ16 × 16.5L) with embossed carrier taping for automatic mounting.
• Wide Temperature Range — Operational from −55°C to 105°C for use across harsh-temperature environments.
• Compliance & Qualification — RoHS compliant and AEC‑Q200 qualified, suitable for designs requiring mapped reliability standards.

Typical Applications

• Automotive Electronics — Bulk filtering and decoupling in automotive control modules and power electronics where AEC‑Q200 qualification and high-temperature endurance are required.
• Compact Power Supplies — Energy storage and smoothing on high-density surface-mount PCBs for DC–DC converters and power rails.
• High-Temperature Systems — Use in electronic assemblies that must operate reliably up to 105°C and maintain performance after extended high-temperature endurance.

Unique Advantages

• High Voltage Handling: 100 V rating supports higher-voltage smoothing and bulk energy storage without series stacking.
• Low Dissipation: tanδ of 0.07 at 120 Hz reduces power loss and heating in AC-biased applications.
• Robust Ripple Capability: Specified ripple currents at both low and high frequencies address dynamic load conditions across switching and linear power stages.
• Automated Assembly Ready: Embossed carrier taping and chip SMD form factor streamline pick-and-place integration on high-density boards.
• Designed for Harsh Environments: −55°C to 105°C range and 5,000-hour endurance at 105°C deliver durability for extended field life.
• Standards and Compliance: RoHS compliance and AEC‑Q200 qualification help meet regulatory and reliability criteria for regulated markets.
