UUG2A331MNQ1MS

The UUG2A331MNQ1MS is a surface-mount aluminum electrolytic capacitor in Nichicon’s UUG series, offering 330 µF capacitance at a 100 V rating. It is a chip-type SMD radial can designed for applications that require high-voltage bulk capacitance in a compact footprint.

Key value propositions include high capacitance at 100 V, AEC-Q200 rating for qualified reliability, and endurance characterized by 2000 hours at 85°C—making it suitable for demanding environments where long-term stability and ripple-handling are required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with ±20% tolerance and a 100 V rated voltage for high-voltage bulk energy storage.
• Dissipation Factor (tan δ) — tanδ 0.08 measured at 20°C, 120 Hz and 100 V, supporting predictable AC loss characteristics at rated conditions.
• Ripple Handling — Low-frequency ripple current 825 mA at 120 Hz and high-frequency ripple current 1.238 A at 100 kHz for smoothing and decoupling on power rails.
• Leakage Current — Specified leakage current of 990 µA, measured after 1 minute at 20°C and rated voltage, for predictable standby losses.
• Reliability & Endurance — Life rated to 2000 hours at 85°C with specified limits on capacitance change and tanδ after endurance testing.
• Temperature Range — Operating range from –40°C to +85°C for use across typical ambient and thermal conditions.
• Package & Footprint — Radial can SMD package, case size φ18 × 21.5 mm (L: 21.5 × D: 18 mm) with surface-mount land size L: 1.83 × W: 1.83 cm for PCB layout planning.
• AEC-Q200 Rated — Component carries an AEC-Q200 rating, indicating qualification for reliability-focused applications that reference that standard.

Typical Applications

• Automotive power subsystems — Bulk energy storage and smoothing on high-voltage automotive power rails up to 100 V, leveraging the AEC-Q200 rating and 330 µF capacitance.
• Power supply filtering — Bulk decoupling and ripple suppression where 825 mA (120 Hz) and 1.238 A (100 kHz) ripple capability are required.
• Control modules and power electronics — High-voltage SMD capacitor for modules that need stable capacitance over long endurance (2000 h at 85°C) and a wide operating temperature range.

Unique Advantages

• High-voltage bulk capacitance: 330 µF at 100 V provides substantial energy storage in a single SMD component, simplifying BOM and board space compared to multi-component solutions.
• Qualified reliability: AEC-Q200 rating supports use in reliability-driven designs where standardized component qualification is required.
• Designed for ripple duty: Specified ripple currents at both low and high frequency enable confident selection for AC and switching environments.
• Predictable loss characteristics: Low tanδ (0.08 at 20°C, 120 Hz) gives a clear basis for thermal and loss budgeting in power circuits.
• Wide operating temperature window: –40°C to +85°C operation supports deployments across varied ambient conditions.
• Compact SMD radial can: φ18 × 21.5 mm case size delivers high capacitance in a board-mountable form factor with documented land-size guidance.
