UBC1C681MNS1MS

The UBC1C681MNS1MS from Nichicon is a surface‑mount aluminum electrolytic capacitor in the UBC series designed for high‑temperature, vibration‑resistant applications. As a chip‑type polarized capacitor, it delivers 680 μF at 16 V in a compact φ12.5 × 13.5 mm can suitable for dense PCB layouts.

Engineered for demanding environments, this part offers extended endurance at elevated temperatures and measurable ripple handling for power‑filtering and bulk‑storage roles in electronics used where heat and mechanical stress are present.

Key Features

• Capacitance and Voltage — 680 μF rated capacitance at 16 V with a tolerance of ±20% (120 Hz, 20°C).
• High‑Temperature Endurance — Rated for continuous operation up to 150°C with a defined life of 1000 hours at 150°C.
• Loss Angle (tan δ) — tanδ 0.18 (measured at 20°C, 120 Hz) for the φ12.5 case, providing a quantified dissipation characteristic.
• Ripple Current Capability — Handles 536 mA at 120 Hz and 800 mA at 10 kHz, supporting both low‑ and high‑frequency ripple conditions.
• Leakage Current — Specified leakage current 326.4 μA (measured after rated voltage application at 20°C, 1 minute condition noted in datasheet methodology).
• Mechanical and Assembly — Chip type, vibration‑resistant radial can in an SMD package (φ12.5 × 13.5 mm) with embossed carrier taping for automated placement.
• Standards & Compliance — AEC‑Q200 qualified and RoHS‑compliant as listed in product data and series documentation.

Typical Applications

• Automotive Electronics — Bulk filtering and smoothing in automotive control modules where high ambient temperatures and vibration resistance are required.
• Power Supply Filtering — Energy storage and ripple suppression on DC rail lines in power management and converter circuits.
• Industrial Equipment — Use in ruggedized industrial electronics that operate at elevated temperatures and experience mechanical stress.
• Embedded Electronics — Decoupling and transient energy support on compact PCBs requiring surface‑mount can‑type capacitors.

Unique Advantages

• Proven high‑temperature capability: 1000‑hour endurance at 150°C gives designers a clear, verifiable thermal performance metric for hot environments.
• Automotive‑grade qualification: AEC‑Q200 listing supports selection for designs targeting vehicle electronics and other demanding applications.
• Measured ripple performance: Specified ripple currents at both 120 Hz and 10 kHz enable reliable selection for mixed‑frequency power systems.
• Vibration‑resistant chip form factor: The φ12.5 can and vibration‑resistant construction reduce mechanical failure risk in mobile and industrial installations.
• SMD‑friendly packaging: Embossed carrier taping simplifies automated assembly and supply‑chain handling for volume production.
• Regulatory compliance: RoHS compliance supports deployment in regions and projects with environmental restrictions.
