UUX2G3R3MNL1GS

The UUX2G3R3MNL1GS from Nichicon is a chip-type, surface-mount aluminum electrolytic capacitor in the UUX series designed for wide temperature operation and high-voltage applications. It provides a 3.3 µF capacitance at a 400 V rating in a compact φ10 × 10 mm can-style SMD package.

Targeted for applications that require AEC‑Q200 qualification and extended endurance, this part combines high working voltage, a wide operating temperature range, and a 3000-hour life at 105°C to support demanding systems in automotive and other harsh environments.

Key Features

• Electrical performance — 3.3 µF capacitance with a rated voltage of 400 V and capacitance tolerance of -20% to +20% (±20% at 120 Hz, 20°C).
• Loss characteristics — Tangent of loss angle (tanδ) specified at 0.25 (max) for 400 V, measured at 20°C and 120 Hz.
• Leakage current — Leakage current specified by the datasheet formula I = 0.04·C·V + 100 µA, yielding 152.8 µA for this 3.3 µF, 400 V unit (measured after 1 minute at 20°C).
• Ripple current — Low-frequency ripple: 38 mA at 120 Hz; high-frequency ripple: 63.46 mA at 10 kHz.
• Wide temperature range — Rated for operation from -40°C to +105°C (category temperature range for 160–400 V parts).
• Endurance — 3000 hours at 105°C with rated voltage applied (specification for 160–400 V parts in the UUX series).
• Package & mounting — Chip-type radial can for SMD mounting, dimension φ10 × 10 mm, surface mount land size 10.3 × 10.3 mm; supplied in embossed carrier taping for automated assembly.
• Qualification — AEC‑Q200 rated per the product specifications, suitable for designs requiring established automotive qualification standards.
• Production status — Mass production availability.

Typical Applications

• Automotive systems — Specified for automotive applications and supplied with AEC‑Q200 rating for use in vehicle electronics that require high-voltage, wide-temperature capacitors.
• Wide-temperature electronic systems — Chip-type construction and a -40°C to +105°C rating accommodate systems that operate across wide ambient temperature ranges.
• High-voltage DC circuits — 400 V rating supports high-voltage DC applications where compact, surface-mount electrolyte capacitance is required.

Unique Advantages

• High working voltage in a compact chip package — 400 V rating in a φ10 × 10 mm SMD can enables designers to integrate high-voltage capacitance into tight PCB real estate.
• Automotive-grade qualification — AEC‑Q200 rating provides specification-level assurance for automotive and similarly demanding applications.
• Measured leakage characterization — Leakage current follows the datasheet formula I = 0.04·C·V + 100 µA, giving a concrete, calculable value (152.8 µA for this part) for design verification.
• Long endurance at elevated temperature — 3000 hours at 105°C under rated voltage supports long-term operation in high-temperature environments.
• Production-ready packaging — Embossed carrier taping facilitates automated placement and downstream assembly processes.
• Defined ripple performance — Specified ripple current values at 120 Hz and 10 kHz help assess thermal and AC stress performance in power circuits.
