UUG2E470MNQ1MS

The UUG2E470MNQ1MS is a surface-mount aluminum electrolytic capacitor from Nichicon's UUG series, offering 47 µF capacitance at a 250 V rating. It is designed for applications requiring high-voltage capacitance in a compact radial can SMD package, with AEC‑Q200 qualification for automotive environments.

Key value propositions include a compact φ18 × 16.5 mm package footprint, defined endurance of 2000 hours at 85°C, and specified ripple current performance across low and high frequencies, enabling reliable power filtering in constrained assemblies.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance, providing defined energy storage for high-voltage circuits.
• Loss Characteristics — tanδ (DF) of 0.16 measured at 20°C, 120 Hz, enabling predictable dissipation behavior in AC and ripple conditions.
• Ripple Performance — Low-frequency ripple current of 415 mA (120 Hz) and high-frequency ripple current of 664 mA (10 kHz), specified to help manage AC stress across a range of switching frequencies.
• Leakage Current — Specified leakage current of 570 µA (measured condition per product data), useful for budgeting steady-state loss in power systems.
• Temperature & Lifetime — Rated for operation from −40°C to +85°C with an endurance rating of 2000 hours at 85°C under rated voltage, supporting durability in thermally demanding duty cycles.
• Package & Assembly — Radial can SMD (φ18 × 16.5 mm) with surface-mount land size 18.3 × 18.3 mm and embossed carrier taping packaging for automated pick-and-place processes.
• AEC‑Q200 Qualified — Built to AEC‑Q200 assessment, suitable for automotive applications where that qualification is required.

Typical Applications

• Automotive Power Electronics — Suitable for power-conditioning roles in automotive systems where a 250 V rated electrolytic capacitor with defined endurance and ripple handling is needed.
• DC Bus and Power Filtering — Used in higher-voltage DC bus decoupling and smoothing duties where compact SMD packaging and specified ripple current performance are required.
• On-board Power Modules — Applicable to electronic control modules and power stage assemblies that need stable capacitance over −40°C to +85°C and endurance at elevated temperature.

Unique Advantages

• High-voltage capability: 250 V rating provides headroom for higher-voltage circuits while maintaining compact SMD packaging.
• Defined ripple specifications: Separate low- and high-frequency ripple current ratings (415 mA @120 Hz; 664 mA @10 kHz) allow designers to account for switching and mains-frequency stress.
• Automotive-grade assessment: AEC‑Q200 rating supports use in automotive designs that require industry-recognized component assessment.
• Durability at elevated temperature: 2000-hour endurance at 85°C gives a clear reliability baseline for thermal budgeting and lifecycle planning.
• Assembly-ready packaging: Embossed carrier taping and a defined surface-mount land footprint facilitate automated placement and PCB integration.
