UUG2W330MNQ1MS

The UUG2W330MNQ1MS is a surface-mount aluminum electrolytic chip capacitor in Nichicon's UUG series designed for higher capacitance, high-voltage applications. It delivers 330 µF at 450 V in a compact chip-style can (φ18 × 21.5 mm), offering elevated bulk energy and filtering capacity in a board-mountable package.

Targeted use includes systems requiring high-voltage smoothing and ripple handling with qualified reliability: the part is AEC-Q200 rated, specified for operation from −40 °C to +85 °C, and has a rated endurance of 2000 hours at 85 °C.

Key Features

• High Voltage & Capacitance — 330 µF capacitance at a 450 V rated voltage for high-energy bulk decoupling and smoothing in high-voltage circuits.
• Ripple Performance — Low-frequency ripple current 345 mA (120 Hz) and high-frequency ripple current 552 mA (10 kHz) to support AC ripple absorption across a wide frequency range.
• Leakage & Polarization — Specified leakage current of 694 µA; polarized construction for conventional electrolytic usage.
• Automotive-Grade Reliability — AEC-Q200 rating and a 2000-hour endurance at 85 °C, suitable for designs requiring defined reliability margins.
• Wide Operating Temperature — Rated for −40 °C to +85 °C to accommodate temperature-variable environments.
• Surface-Mount Chip Can Package — Chip-type, radial can SMD (φ18 × 21.5 mm) with embossed carrier taping for automated placement and PCB assembly.

Typical Applications

• Automotive Electronics — Energy storage and smoothing in vehicle electronic modules where AEC-Q200 qualification is required.
• High-Voltage Power Supplies — Bulk filtering and ripple suppression in high-voltage power conversion and supply rails.
• Industrial Power Systems — Decoupling and buffering in industrial converters and power regulation equipment operating across −40 °C to +85 °C.

Unique Advantages

• High-voltage energy density: 330 µF at 450 V enables substantial bulk capacitance in a single surface-mount component, reducing the need for multiple discrete capacitors.
• Frequency-flexible ripple handling: Rated ripple currents specified at both low (120 Hz) and high (10 kHz) frequencies, supporting mixed-frequency ripple environments.
• Automotive-level qualification: AEC-Q200 rating provides a defined reliability envelope for designs targeting automotive or similarly demanding applications.
• Robust thermal endurance: 2000 hours at 85 °C endurance specification supports designs with sustained elevated operating temperatures.
• Surface-mount packaging: Embossed carrier taping and chip can SMD format simplify automated assembly and save PCB area compared with radial-leaded options.
