UUX0J331MNL1GS

The UUX0J331MNL1GS is a surface-mount aluminum electrolytic capacitor from Nichicon’s UUX series, delivering 330 µF at a rated 6.3 V in a compact φ8 × 10 mm can-style SMD package. Designed for wide temperature operation and long endurance, it targets power smoothing and decoupling in demanding electronic systems, including automotive applications where an AEC-Q200 rating is required.

This part combines high capacitance density, defined ripple performance at both low and high frequencies, and embossed carrier tape packaging for automated placement and high-volume assembly.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a rated voltage of 6.3 V, with a tolerance of -20% to +20%.
• Temperature Range & Endurance — Operating range from -55°C to 105°C with an endurance rating of 2000 hours at 105°C.
• Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.22 measured at 20°C, 120 Hz for the 6.3 V rating.
• Ripple Current Performance — Low-frequency ripple current of 288 mA at 120 Hz and high-frequency ripple current of 374.4 mA at 10 kHz, supporting both bulk filtering and higher-frequency decoupling.
• Leakage Current — Specified leakage current of 62.37 µA, measured per product test conditions.
• Package & Mounting — φ8 × 10 mm radial can-style SMD (chip type) packaged for surface mount, supplied in embossed carrier taping for automated pick-and-place.
• Automotive Grade — Meets AEC-Q200 requirements as indicated in the product specifications.

Typical Applications

• Automotive power electronics — Bulk smoothing and decoupling on 6.3 V rails for in-vehicle control units and modules where AEC-Q200 qualification is needed.
• DC-DC converters — Output filtering and energy storage for converters requiring stable ripple performance across low and high frequency ranges.
• Embedded power supplies — Local energy buffering and transient suppression in compact SMD footprints for industrial and automotive electronics.

Unique Advantages

• Compact, high-capacitance SMD form factor — 330 µF in a φ8 × 10 mm can supports space-constrained designs without sacrificing capacitance.
• Wide temperature capability — Rated for -55°C to 105°C operation with a 2000-hour endurance at 105°C, enabling reliable performance in harsh thermal environments.
• Dual-frequency ripple handling — Specified ripple current at both 120 Hz and 10 kHz provides clear performance targets for designers addressing bulk and high-frequency noise.
• Automotive-capable qualification — Inclusion of AEC-Q200 in the specifications supports use in applications requiring automotive stress-testing conformance.
• Production-ready packaging — Embossed carrier taping facilitates high-throughput SMT assembly and inventory handling in mass-production environments.
