UUX1C331MNL1GS

The UUX1C331MNL1GS is a surface-mount aluminum electrolytic capacitor from Nichicon's UUX series, designed as a chip-type device with a wide operating temperature range. It delivers 330 µF capacitance at a 16 V rating with specifications aimed at demanding environments.

Targeted for automotive applications, this part combines a compact radial can SMD package (φ10 × 10 mm) with AEC-Q200 qualification, long-term endurance at elevated temperature, and measured ripple/leakage characteristics useful in power filtering and voltage stabilization tasks.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 16 V and a capacitance tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Wide Temperature Range — Specified for operation from −55°C to 105°C, supporting applications that require stability across extreme ambient conditions.
• AEC-Q200 Qualified — Designed to meet AEC-Q200 requirements for component-level automotive qualification.
• Endurance — Rated for 2000 hours at 105°C with the rated voltage applied; capacitance change is specified within ±20% after the endurance test.
• Tangent of Loss Angle (tan δ) — tan δ of 0.16 (maximum) measured at 120 Hz, 20°C, indicating the specified dissipation characteristics at the rated voltage.
• Ripple Current Performance — Low-frequency ripple current of 441 mA at 120 Hz and high-frequency ripple current of 573.3 mA at 10 kHz, supporting AC performance needs in power circuits.
• Leakage Current — Specified leakage current of 158.4 µA, measured after rated voltage application at standard conditions.
• Package & Assembly — Compact radial can SMD package (φ10 × 10 mm) with embossed carrier taping for automated surface-mount assembly.
• Production Status — Mass production availability from the manufacturer Nichicon.

Typical Applications

• Automotive systems — Use in electronic control units and subsystem power rails that require components meeting AEC-Q200 and a wide −55°C to 105°C operating range.
• Automotive high-temperature environments — Suitable where sustained performance at elevated ambient temperatures is required, supported by 2000-hour endurance at 105°C.
• Automotive power filtering — Applicable for smoothing and ripple suppression on 16 V power rails, backed by specified low- and high-frequency ripple current ratings.

Unique Advantages

• AEC-Q200 qualification: Enables use in automotive applications that require component-level qualification and traceable specifications.
• Wide operating temperature: −55°C to 105°C rating supports deployment across harsh thermal environments without losing defined performance margins.
• Long endurance at high temperature: 2000 hours at 105°C with rated voltage ensures predictable life characteristics for longevity-sensitive designs.
• Compact SMD radial can: φ10 × 10 mm package minimizes board footprint while providing electrolytic capacitance density for power circuits.
• Measured ripple performance: Defined low- and high-frequency ripple currents (441 mA at 120 Hz, 573.3 mA at 10 kHz) help designers size capacitors for real-world AC loading.
• Assembly-ready packaging: Embossed carrier taping facilitates automated pick-and-place and reflow-compatible assembly processes.
