UCM1K101MNS1GS

The UCM1K101MNS1GS is a chip-type, low-impedance aluminum electrolytic capacitor in a surface-mount radial can package designed for demanding electronic environments. With an 80 V rated voltage, 100 µF capacitance and AEC-Q200 qualification, it targets automotive and other high-reliability applications that require high-voltage bulk capacitance in a compact SMD footprint.

Key value propositions include wide operating temperature range (−55 °C to 105 °C), vibration resistance and embossed carrier taping for automated assembly — delivering a compact, high-voltage, long-life capacitor option for robust system designs.

Key Features

• Core Capacitance — 100 µF nominal capacitance with tolerance −20% to +20% at 120 Hz, 20 °C for predictable bulk energy storage.
• High Voltage Rating — Rated voltage 80 V to support higher-voltage rails and power stages.
• Low Impedance Chip Type — Chip-type, low-impedance construction for improved AC performance and ripple handling.
• Loss Characteristics — tanδ (DF) 0.08 measured at 20 °C, 120 Hz, supporting stable dissipation performance at rated voltage.
• Ripple Current Capability — 250 mA at 120 Hz (low frequency) and 500 mA at 10 kHz (high frequency) for effective ripple filtering and decoupling.
• Leakage Current — Specified leakage current of 80 µA after standard voltage application.
• Temperature and Endurance — Operating range −55 °C to 105 °C and rated endurance of 2000 hours at 105 °C (per part sizing), suitable for sustained elevated-temperature operation.
• Mechanical & Assembly — Compact φ10 × 10L can (L: 1.0 cm × D: 1.0 cm) with vibration-resistant construction and embossed carrier taping for automated placement.
• Compliance — AEC-Q200 rated and RoHS compliant, aligning with automotive and regulatory requirements.

Typical Applications

• Automotive power electronics — Bulk and decoupling capacitance on higher-voltage rails where 80 V rating and high ripple current capability are required.
• In-vehicle control modules — Stable energy storage for electronic control units and modules that operate across −55 °C to 105 °C.
• DC–DC converters and power supplies — Output filtering and ripple suppression at both low and high frequencies using the specified ripple current ratings.

Unique Advantages

• AEC-Q200 qualification: Provides an automotive-grade qualification baseline for designs that need recognized reliability standards.
• 80 V rating in an SMD can: Enables higher-voltage system designs without sacrificing PCB space.
• High-frequency ripple handling: 500 mA ripple current at 10 kHz helps reduce voltage ripple in switching power stages.
• Wide temperature capability: −55 °C to 105 °C operation and 2000-hour endurance at 105 °C support long-term performance in elevated-temperature environments.
• Automated assembly ready: Embossed carrier taping and compact φ10 package simplify pick-and-place and high-volume production.
• Vibration resistant: Mechanical construction suited for applications where vibration resistance is required.
