UUJ1J680MNJ1MS

The UUJ1J680MNJ1MS is a chip-type aluminum electrolytic capacitor from Nichicon's UUJ series, offering 68 µF capacitance at a 63 V rating in a compact SMD can package. It is designed for surface mounting on high-density printed circuit boards and is compatible with automatic mounting machines fed by carrier tape.

Its construction and qualification make it suitable for demanding environments, with an operating temperature range down to −55 °C, long-term endurance at elevated temperature, and AEC-Q200 qualification for automotive applications.

Key Features

• Electrical Performance — 68 µF capacitance at 63 V with ±20% tolerance and polarized construction for DC energy storage, smoothing and decoupling in power circuits.
• Temperature & Lifetime — Rated for operation from −55 °C to +105 °C with a 5000-hour endurance at 105 °C under rated voltage conditions.
• Ripple Current Capability — Specified ripple current of 175 mA at 120 Hz and 350 mA at 10 kHz, supporting AC superposition on DC rails within these test conditions.
• Package & Mounting — Chip-type radial can for surface-mount applications; designed for high-density PCBs and compatible with carrier-tape automatic pick-and-place processes.
• Physical Dimensions — Compact footprint: 1.35 cm (length) × 1.25 cm (diameter); recommended land pattern 1.28 cm × 1.28 cm to match the SMD can form factor.
• Automotive Qualification & Compliance — AEC-Q200 qualified and RoHS-compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive PCB assemblies — Surface-mount form factor and AEC-Q200 qualification support use on high-density automotive circuit boards where standardized qualification is required.
• Automotive modules assembled with automated pick-and-place — Designed for compatibility with carrier-tape feeding and automatic mounting machines for efficient production.
• High-density electronic boards — Chip-style SMD can enables higher capacitance in compact footprints for space-constrained power or control boards.

Unique Advantages

• High capacitance in an SMD can — Provides 68 µF at 63 V in a chip-type package that supports compact board layouts.
• Automotive-grade qualification — AEC-Q200 qualification provides documented suitability for automotive design flows and reliability expectations.
• Wide operating temperature and proven endurance — −55 °C to +105 °C range and 5000 hours at 105 °C support long-term operation in elevated-temperature environments.
• Mounting and assembly efficiency — Designed for surface mounting on high-density PCBs and compatible with automatic carrier-tape mounting to streamline manufacturing.
• Regulatory compliance — RoHS-compliant construction supports modern environmental and regulatory requirements.
• Measured ripple handling — Specified ripple current at both low and high frequencies (175 mA at 120 Hz; 350 mA at 10 kHz) helps designers assess AC performance on DC rails.
