UUJ2G330MNJ6MS

The UUJ2G330MNJ6MS is a chip-type aluminum electrolytic capacitor in the Nichicon UUJ series, delivering 33 µF capacitance at a 400 V rating in a compact surface-mount can. It is designed for high-density PCBs and is compatible with automatic mounting machines using carrier tape.

Targeted for demanding environments, the component combines high-voltage capability, long endurance at elevated temperature, and automotive-grade qualification (AEC‑Q200) for use in vehicle electronics and other rugged electronic assemblies.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance rated for 400 V DC with ±20% tolerance (measured at 120 Hz, 20°C).
• Package & Mounting — Chip-type radial can SMD package engineered for surface mounting on high-density PC boards and compatible with automatic carrier-tape feeding.
• Temperature & Endurance — Operating range −40°C to +105°C with endurance specified as 5000 hours at 105°C under rated voltage.
• Automotive Qualification — AEC‑Q200 qualified, supporting use in automotive electronic modules and other applications requiring component-level automotive qualification.
• Ripple Current — Rated ripple current of 160 mA at 120 Hz and 256 mA at 10 kHz for effective smoothing in power circuits.
• Leakage Current Specification — For rated voltages 160–450 V the datasheet leakage-current limit is I = 0.04·C·V + 100 µA (1 minute at 20°C); applying this to 33 µF at 400 V yields a maximum leakage of 628 µA at 1 minute, per the series specification.
• Low-Temperature Behavior — Impedance increases at low temperature are defined by the series: up to 6× at −25°C and up to 10× at −40°C versus +20°C for the 400–450 V group.
• RoHS Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).
• Mechanical Footprint — Component dimensions L: 21.5 mm × D: 18 mm with recommended SMT land size L: 18.3 mm × W: 18.3 mm for board layout reference.

Typical Applications

• Automotive Electronic Modules — Data supports use in automotive systems where AEC‑Q200 qualification and high-voltage filtering are required.
• High‑Voltage Power Supplies — 400 V rating and specified ripple currents make this capacitor suitable for smoothing and decoupling in high-voltage power circuits on compact PCBs.
• High-Density PCB Assemblies — Chip-type SMD can and carrier-tape compatibility enable automated placement in space-constrained, high-density boards.

Unique Advantages

• Automotive-Grade Qualification: AEC‑Q200 qualification provides documented robustness for vehicle electronics and other mission-critical applications.
• High-Voltage Capability: 400 V rating enables use in higher-voltage domains without adding bulk to the design.
• Long High‑Temperature Endurance: Rated for 5000 hours at 105°C under applied voltage, supporting long-term thermal reliability in demanding environments.
• SMD Compatibility for Automated Assembly: Chip-type can and carrier-tape support streamline pick‑and‑place production on high-density boards.
• Defined Leakage and Impedance Characteristics: Series-level specifications for leakage current, tan δ, and low-temperature impedance give predictable electrical behavior across conditions.
• Regulatory Compliance: RoHS compliance supports regulatory requirements for commercial and automotive supply chains.
