The UCD1K680MNS1MS is a surface-mount aluminum electrolytic capacitor from Nichicon's UCD series, offering 68 µF capacitance at an 80 V rating. It is a chip‑type, low‑impedance SMD can designed for high-density PCBs and automated assembly processes.

Targeted for demanding electronic assemblies including automotive modules, the part combines a wide operating temperature range and long endurance to support reliable, space-efficient power decoupling and filtering in compact designs.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with an 80 V rated voltage and a tolerance of −20% to +20%.
• Low‑loss, Low‑impedance — Tangent of loss angle (tan δ) of 0.08 measured at 20°C, 120 Hz, providing predictable AC performance for decoupling and filtering.
• Ripple Current Performance — Rated for 250 mA low‑frequency ripple at 120 Hz and 500 mA high‑frequency ripple at 10 kHz, supporting both mains‑band and switching noise applications.
• Endurance & Temperature — Rated lifetime of 5000 hours at 105°C and a category temperature range from −55°C to 105°C for sustained operation in elevated ambient temperatures.
• Package & Mounting — Chip‑type radial can SMD (φ12.5 × 13.5L; size L: 1.35 × D: 1.25 cm) optimized for surface mounting; supplied in embossed carrier taping for automated pick‑and‑place.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS compliant; vibration resistant and available in mass production status.
• Leakage Current — Specified leakage current of 54.4 µA for predictable standby behavior in power circuits.

Typical Applications

• Automotive Electronic Modules — Suitable for use in automotive control and power modules where AEC‑Q200 qualification and operation to 105°C are required.
• High‑Density PCBs — Chip‑type SMD can and embossed carrier taping make it appropriate for compact board layouts and automated assembly on high‑density PCBs.
• Power Filtering and Decoupling — Low tan δ and specified ripple current ratings address both low‑frequency and high‑frequency filtering needs in power supplies and DC/DC stages.
• Vibration‑Sensitive Equipment — Vibration‑resistant construction supports use in environments subject to mechanical stress.

Unique Advantages

• AEC‑Q200 Qualification: Provides an established automotive reliability baseline for designs requiring industry qualification.
• Long Endurance at Elevated Temperature: 5000 hours at 105°C supports extended life in high‑temperature applications.
• Automated Assembly Ready: Embossed carrier taping and chip SMD form factor enable streamlined pick‑and‑place insertion into production lines.
• Balanced AC Performance: Low tan δ and defined ripple current ratings at both 120 Hz and 10 kHz help manage both bulk and switching noise.
• Compact SMD Can: φ12.5 × 13.5L package offers a space‑efficient solution for high‑density boards without sacrificing rated voltage.
• Regulatory Compliance: RoHS compliant for global environmental requirements.
