UUG2G330MNQ1MS

The UUG2G330MNQ1MS is a surface-mount aluminum electrolytic capacitor from Nichicon's UUG series designed for demanding power applications. It delivers a 33 µF capacitance at a 400 V rating in a compact φ18 × 21.5 mm can-style SMD package.

Engineered for use in automotive and industrial power electronics, the device combines high-voltage capability, defined ripple performance at low and high frequencies, and a qualified endurance specification to support robust power smoothing and decoupling functions.

Key Features

• Electrical Performance  33 µF capacitance with ±20% tolerance and a rated voltage of 400 V; designed for high-voltage SMD power circuits.
• Loss & Leakage  tan δ (DF) of 0.25 (measured at 20°C, 120 Hz) and a specified leakage current of 628 µA for predictable idle-state behavior.
• Ripple Current Capability  Low-frequency ripple current 350 mA (120 Hz) and high-frequency ripple current 560 mA (10 kHz), supporting both mains-frequency and switching-frequency filtering.
• Reliability & Endurance  Rated for 2000 hours at 85°C and an operating temperature range of −40°C to +85°C to meet sustained elevated-temperature use cases.
• Package & Mounting  φ18 × 21.5 mm radial can in an SMD configuration with embossed carrier taping for automated placement.
• Automotive Qualification  AEC-Q200 rating, indicating suitability for automotive system designs where that qualification is required.

Typical Applications

• Automotive power electronics  Use in vehicle power supplies and electronic modules where a 400 V-rated SMD electrolytic capacitor is required for smoothing and decoupling.
• DC link and power conversion  Suitable for high-voltage DC link filtering and energy storage on board-level converters in automotive and industrial systems.
• Switching power supplies  Provides ripple handling across low and high frequencies to support stable output in switching regulators and inverters.

Unique Advantages

• High-voltage SMD capability: 400 V rating enables use in high-voltage board-level designs without bulky through-hole components.
• Frequency-flexible ripple handling: Defined ripple currents at 120 Hz and 10 kHz allow the same part to address both mains-frequency and switching-frequency requirements.
• Qualified for automotive use: AEC-Q200 rating supports integration into automotive subsystems with defined qualification criteria.
• Compact can-style SMD package: φ18 × 21.5 mm can in embossed carrier taping supports automated placement while conserving board area relative to larger options.
• Endurance at elevated temperature: 2000 hours at 85°C provides a measurable reliability baseline for long-term operation in warm environments.
