UCD1K680MNQ1MS

The UCD1K680MNQ1MS is a chip-type aluminum electrolytic capacitor designed for surface-mount assembly. It combines a low-impedance construction with an 80 V rated voltage and 68 µF capacitance for power-filtering and decoupling roles in compact PCBs.

Engineered for high-temperature operation and automated production, the part is AEC-Q200 qualified, RoHS compliant, and supplied in embossed carrier taping for pick-and-place compatibility. Key operating parameters include a −55 °C to 105 °C temperature range and a 5000-hour endurance at 105 °C.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance for reliable energy storage and voltage handling.
• Low-Impedance Chip Type — Chip-type, low-impedance construction targeted at minimizing AC loss in high-density surface-mount designs.
• Loss Tangent (tan δ) — tan δ = 0.08 (measurement at 20 °C, 120 Hz for the 80 V rating), indicating controlled dissipation at mid-band frequencies.
• Ripple Current Capability — Low-frequency ripple current 250 mA (120 Hz) and high-frequency ripple current 500 mA (10 kHz), supporting smoothing and decoupling under AC load.
• Leakage Current — Specified leakage current of 54.4 µA after rated voltage application, aiding predictable bias behavior in power circuits.
• High-Temperature Endurance — Rated for 5000 hours at 105 °C, enabling sustained operation in thermally demanding environments.
• Automotive-Grade Reliability — AEC-Q200 qualification for use in automotive electronics where applicable.
• Surface-Mount Packaging — Radial can SMD (φ12.5 × 13.5 mm) supplied in embossed carrier taping for automated board assembly; recommended surface land size 12.8 × 12.8 mm.
• Wide Temperature Range — Operational from −55 °C to 105 °C for broad environmental tolerances.
• RoHS Compliant — Conforms to RoHS directives for restricted substances.

Typical Applications

• Automotive Power Systems — Used for bulk filtering and decoupling in vehicle power electronics where AEC-Q200 qualification and wide temperature range are required.
• On-board Power Supplies — Smoothing and energy storage for DC–DC converters and regulator outputs operating up to 80 V.
• Industrial Power Modules — Local decoupling in compact, high-density boards that demand automated SMD assembly and robust ripple handling.

Unique Advantages

• Low-Impedance Design: The chip-type, low-impedance construction and measured tan δ provide reduced AC loss compared to higher-loss alternatives, improving filtering performance.
• High Voltage and Ripple Capability: 80 V rating combined with specified ripple currents (250 mA @120 Hz, 500 mA @10 kHz) supports demanding power-conditioning tasks.
• High-Temperature Reliability: 5000-hour endurance at 105 °C delivers predictable long-term behavior in thermally stressed assemblies.
• Automated Assembly Ready: Embossed carrier taping and an SMD radial can package simplify pick-and-place integration for high-volume production.
• Automotive Qualification: AEC-Q200 rating provides traceable qualification for vehicle electronic systems where applicable.
• Regulatory Compliance: RoHS conformity reduces material-restriction risk during product deployment.
