UUG2G220MNQ1MS

The UUG2G220MNQ1MS from Nichicon is a surface-mount aluminum electrolytic capacitor in the UUG series designed for higher-capacitance chip applications. It offers 22 µF capacitance at a 400 V rating in a compact φ18 × 16.5 mm can-style SMD package.

Engineered for demanding environments, this part combines high-voltage capability, controlled dissipation factor and measurable ripple performance with automotive-grade AEC-Q200 qualification—making it suitable for automotive power electronics and other applications requiring robust, high-voltage SMD capacitors.

Key Features

• Capacitance & Tolerance — 22 µF nominal with a tolerance of -20% to +20% at 120 Hz, 20°C.
• High Voltage Rating — Rated voltage: 400 V for high-voltage DC applications.
• Dissipation Factor (tan δ) — tanδ = 0.25 (measured at 20°C, 120 Hz), allowing predictable loss characteristics for design calculations.
• Ripple Current Performance — Low-frequency ripple current 280 mA at 120 Hz and high-frequency ripple current 448 mA at 10 kHz for reliable AC ripple handling.
• Leakage Current — Specified leakage current: 452 µA (after 1 minute at 20°C), enabling accurate standby and leakage budgeting.
• Reliability / Endurance — Rated endurance: 2000 hours at 85°C with specified recovery characteristics after test.
• Temperature Range — Operational from -40°C to +85°C to support a wide range of ambient conditions.
• Package & Mounting — Radial, can-style SMD (chip type) with surface-mount land size L: 1.83 × W: 1.83 cm; supplied in embossed carrier taping for automated placement.
• Automotive Qualification — AEC-Q200 rated for automotive application suitability.
• Lifecycle Status — End Of Life (EOL).

Typical Applications

• Automotive power systems — Supports high-voltage smoothing and decoupling in automotive electronic modules where AEC-Q200 qualification is required.
• On-board power supplies — Useful for bulk filtering and ripple attenuation in compact SMD power supply designs operating up to 400 V.
• High-voltage DC circuits — Applied where a 400 V-rated SMD electrolytic is needed for energy storage and transient absorption.

Unique Advantages

• High-voltage capability: 400 V rating enables use in higher-voltage DC circuits without additional series components.
• Automotive-grade reliability: AEC-Q200 rating plus 2000 h endurance at 85°C support deployment in automotive electronics.
• Compact SMD can: φ18 × 16.5 mm chip form factor provides higher capacitance in a board-mountable package for space-constrained designs.
• Measurable ripple handling: Specified ripple currents at 120 Hz and 10 kHz give clear limits for thermal and ripple budgeting.
• Predictable leakage and loss: Specified leakage current and tanδ allow accurate power-loss and standby current estimates.
• Production-ready packaging: Embossed carrier taping supports automated pick-and-place and assembly workflows.
