UUG0J682MNJ1MS

The UUG0J682MNJ1MS is a high-capacitance, surface-mount aluminum electrolytic capacitor from Nichicon's UUG series. It delivers 6800 µF at 6.3 V in a compact SMD can package (φ18 × 21.5 mm) designed for use where large bulk capacitance and robust electrical performance are required.

Targeted for applications that demand long endurance and elevated ripple handling, this part offers AEC‑Q200 qualification, a wide operating temperature range of −40 °C to 85 °C, and an endurance rating of 2000 hours at 85 °C.

Key Features

• High Capacitance — 6800 µF (6.8 mF) nominal capacitance for bulk energy storage and smoothing in power rails.
• Rated Voltage & Tolerance — 6.3 V rated voltage with capacitance tolerance of −20% to +20% (±20% at 120 Hz, 20 °C).
• Ripple Current Performance — Low-frequency ripple current of 1.65 A at 120 Hz and high-frequency ripple current of 1.8975 A at 10 kHz to support high-load and switching applications.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.34 measured at 20 °C, 120 Hz, provided for design verification of ESR-related loss.
• Leakage Current — Specified leakage current of 2040 µA (measured after 1 minute at 20 °C under rated voltage) for predictable standby behavior.
• Reliability & Endurance — Life rating of 2000 hours at 85 °C; AEC‑Q200 qualification supports usage in demanding environments.
• Form Factor & Mounting — φ18 × 21.5 mm SMD can (radial, can – SMD) suitable for automated assembly; supplied in embossed carrier taping for pick-and-place lines.
• Operating Range — Specified for −40 °C to 85 °C operation to match a broad range of environmental conditions.

Typical Applications

• Automotive systems — AEC‑Q200 qualification and high bulk capacitance make this capacitor suitable for automotive electronics that require robust power storage and ripple filtering.
• Power supply smoothing — Large capacitance and rated ripple current support DC bus and post-regulator smoothing in compact SMD implementations.
• High‑frequency switching environments — Specified high-frequency ripple current performance (1.8975 A at 10 kHz) for applications involving switching converters and inverters.

Unique Advantages

• Large capacitance in an SMD can — 6800 µF in a φ18 × 21.5 mm package provides substantial bulk energy storage while keeping the part compatible with surface-mount assembly.
• Designed for ripple-heavy circuits — Dual ripple current ratings at 120 Hz and 10 kHz allow engineers to evaluate performance across the frequency spectrum relevant to switching and legacy line-frequency systems.
• AEC‑Q200 qualified — Built to an automotive-oriented reliability standard to support use in demanding and mission-critical electronic systems.
• Long endurance at elevated temperature — 2000 hours at 85 °C enables predictable lifetime planning for thermal stress environments.
• Production-ready packaging — Embossed carrier taping streamlines automated placement and reduces handling time in high-volume assembly.
• Wide operating temperature — −40 °C to 85 °C rating supports deployment across a broad set of environmental conditions.
