UUJ1H331MNJ6MS

The UUJ1H331MNJ6MS is a chip-type aluminum electrolytic capacitor in Nichicon’s UUJ series, engineered for surface-mount use on high-density printed circuit boards. It delivers 330 µF nominal capacitance at a 50 V rating and is designed for automated assembly with carrier-tape compatibility.

Targets include automotive and other demanding electronic systems where AEC-Q200 qualification, wide temperature range, and long-term endurance are required. The part combines higher capacitance in larger chip case sizes with surface-mount convenience for compact, production-friendly designs.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 50 V rated voltage and tolerance of ±20% (−20% to +20%).
• Package & Mounting — Chip-type radial can SMD package designed for surface mounting on high-density PC boards; compatible with automatic mounting machines fed by carrier tape.
• Operating Temperature & Endurance — Rated for −55 °C to +105 °C operation and specified for 5000 hours at 105 °C.
• Reliability & Qualification — AEC-Q200 Qualified for applications requiring automotive-grade component qualification; RoHS compliant (2011/65/EU, (EU)2015/863).
• Ripple Current Capability — Rated ripple current of 440 mA at 120 Hz (low frequency) and 660 mA at 10 kHz (high frequency), supporting real-world power applications where ripple handling matters.
• Electrical Losses & Leakage — Tangent of loss angle (tan δ) max 0.12 at 120 Hz, 20 °C for 50 V parts; leakage current after 1 minute at 20 °C is specified as not more than 0.03CV (µA) for rated voltages in the 10–100 V range.
• Mechanical & Land Pattern — Case dimensions L × D: 2.1 × 1.25 cm with recommended surface-mount land size L × W: 1.28 × 1.28 cm for PCB footprint planning.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and wide temperature capability make this capacitor suitable for automotive electronic modules that require reliable electrolytic capacitance.
• High-density Surface-mount Boards — Chip-type radial can package is optimized for placement on compact, densely populated PCBs where space and automated assembly are priorities.
• Automated Assembly Lines — Designed for carrier-tape feeding and compatibility with automatic mounting machines to streamline production and reduce assembly cycle time.

Unique Advantages

• Higher Capacitance in Chip Form — Provides 330 µF in a chip-type SMD can, enabling larger capacitance values on surface-mount, space-constrained designs.
• AEC-Q200 Qualified — Qualification for automotive-grade use provides confidence for applications that require recognized component reliability standards.
• Long High-temperature Life — Specified 5000 hours at 105 °C with defined endurance limits (capacitance variation within ±20%, tan δ within specified limits, leakage within initial spec), supporting long-term stability under thermal stress.
• Measurable Ripple Handling — Specified ripple current ratings at both low and high frequencies allow designers to match capacitor selection to expected ripple conditions in power subsystems.
• Production-friendly Packaging — Carrier-tape compatible and surface-mount friendly packaging simplifies high-volume manufacturing and automated PCB assembly.
• Regulatory Compliance — RoHS-compliant construction supports use in regulated markets and simplifies environmental compliance for assemblies.
