UUJ1J331MNQ1MS

The UUJ1J331MNQ1MS is a chip-type aluminum electrolytic capacitor in a radial can SMD package offering 330 µF capacitance at 63 V. Designed for surface mounting on high-density printed circuit boards, it delivers elevated capacitance in larger chip case sizes (φ18 × 16.5L) for demanding power-filtering and decoupling tasks.

Engineered with AEC‑Q200 qualification and RoHS compliance, this part targets automotive and other reliability-conscious applications that require long-term stability across a wide temperature range.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a rated voltage of 63 V with ±20% tolerance, suitable for bulk decoupling and smoothing.
• Package & Mounting — Chip-type radial can designed for surface-mount assembly; compatible with automatic mounting machines fed with carrier tape for high-density PCBs.
• Thermal & Lifetime Performance — Operates from −55°C to +105°C with an endurance rating of 5000 hours at 105°C.
• Ripple Current — Rated ripple handling of 490 mA at 120 Hz and 735 mA at 10 kHz for AC ripple and switching-power applications.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS directive (2011/65/EU, (EU)2015/863) compliant for regulated environments.
• Polarized Construction — Standard polarized aluminum electrolytic design with black top-case marking for polarity and part identification.
• Board Footprint — Package dimensions L: 1.65 cm × D: 1.8 cm with a recommended surface-mount land size of 1.83 × 1.83 cm to simplify PCB design.

Typical Applications

• Automotive electronic modules — AEC‑Q200 qualification and wide operating temperature range make the part suitable for power filtering in automotive systems.
• Power supply smoothing — 330 µF at 63 V combined with specified ripple-current ratings supports bulk smoothing and hold-up in DC–DC converters and regulators.
• High-density SMD assemblies — Chip-type SMD form factor and tape-fed mounting compatibility enable automated placement on compact, densely populated PCBs.

Unique Advantages

• Higher capacitance in compact SMD can — Provides 330 µF in a φ18×16.5L chip case to increase energy storage without switching to discrete radial components.
• Designed for automated assembly — Compatible with carrier-tape feeding for placement on high-volume SMT lines, reducing assembly complexity.
• Validated for harsh environments — AEC‑Q200 qualification and a −55°C to +105°C operating range support deployment in temperature‑challenging applications.
• Long-term stability at elevated temperature — Endurance rating of 5000 hours at 105°C provides predictable aging characteristics for long-life designs.
• Measurable ripple performance — Specified ripple currents at 120 Hz and 10 kHz let engineers size the capacitor for expected AC stress in switching and linear supplies.
• Regulatory compliance — RoHS conformity eases integration into products subject to environmental directives.
