UUJ2G220MNQ1MS

The UUJ2G220MNQ1MS is a chip-type aluminum electrolytic capacitor from Nichicon's UUJ series, designed for surface mounting on high-density printed circuit boards. It delivers 22 µF capacitance at 400 V in a compact radial-can SMD package suitable for automated carrier-tape assembly.

Built and specified for demanding environments, this part offers AEC-Q200 qualification and RoHS compliance, with electrical and thermal characteristics intended for automotive and similarly demanding embedded systems.

Key Features

• Core Electricals: 22 µF nominal capacitance with ±20% tolerance and 400 V rated voltage. Polarized aluminum electrolytic construction optimized for higher-capacitance chip form factors.
• Automotive Qualification & Compliance: AEC-Q200 Qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting vehicle-grade reliability and regulatory requirements.
• Thermal & Lifetime Performance: Operating temperature range −40 °C to +105 °C with a published endurance of 5000 hours at 105 °C under rated voltage conditions.
• Ripple Handling: Ripple current capability of 130 mA at 120 Hz and 208 mA at 10 kHz, supporting AC ripple absorption and smoothing in compact assemblies.
• Leakage Current (Series Characteristic): For rated voltages in the 160–450 V range, leakage after 1 minute at 20 °C follows I = 0.04·C·V + 100 µA (series specification).
• Impedance & Loss: Series tan δ limit for 400–450 V products is specified at 0.20 (120 Hz, 20 °C); low-temperature impedance ratios for this voltage group are defined in the UUJ series specifications.
• Surface-Mount Packaging & Assembly: Radial can SMD package designed for automatic mounting from carrier tape; compact dimensions L 2.15 × D 1.8 cm with recommended land size L 1.83 × W 1.83 cm to support high-density PCB layouts.

Typical Applications

• Automotive Electronics: Suitable for vehicle electronic modules where AEC-Q200 qualification and wide operating temperature range are required.
• High-density PCB Power Modules: Compact SMD radial-can form enables high-capacitance placement on tightly packed power boards and assemblies.
• Automated Assembly Environments: Designed for carrier-tape feeding and placement by automatic mounting machines to streamline high-volume production.

Unique Advantages

• AEC-Q200 Qualified: Meets series-level automotive qualification, helping accelerate inclusion in vehicle-grade designs and reliability programs.
• High Voltage in a Chip Form Factor: 400 V rating combined with 22 µF capacitance provides energy storage capability for compact power circuitry without a large footprint.
• Long Endurance at Elevated Temperature: 5000 hours at 105 °C endurance supports demanding thermal environments and extended service life planning.
• Designed for Automated Production: Carrier-tape compatible SMD package reduces manual handling and supports efficient pick-and-place assembly flows.
• Clear Performance Parameters: Published ripple current figures and leakage current formula allow predictable thermal and electrical design margins.
• Regulatory Compliance: RoHS conformance simplifies environmental compliance for global product programs.
