UUG2A221MNJ6MS

The UUG2A221MNJ6MS is a surface-mount aluminum electrolytic capacitor in Nichicon’s UUG series, offering 220 µF capacitance at a 100 V rating. It is a chip-type, higher-capacitance SMD can designed for applications that require compact bulk capacitance and robust ripple handling.

Designed for demanding environments, the part combines a 220 µF, 100 V rating with AEC-Q200 qualification and a 2000-hour endurance at 85°C, making it suitable for systems where high voltage, ripple capability and long-term reliability are important.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance, providing substantial bulk storage for high-voltage power rails.
• Loss Characteristics: Tangent of loss angle (tanδ) of 0.08 measured at 20°C, 120 Hz (at the 100 V rating), enabling predictable dissipation behavior at rated conditions.
• Ripple Current Handling: Low-frequency ripple current of 665 mA (120 Hz) and high-frequency ripple current of 997.5 mA (10 kHz), supporting AC ripple smoothing across a wide frequency range.
• Leakage Current: Specified leakage current of 660 µA (after rated voltage applied, at 20°C), useful for power-budget and hold-up time calculations.
• Reliability & Endurance: Endurance of 2000 hours at 85°C with capacitance change within ±20% and controlled increase in tanδ, providing a defined life metric for thermal stress planning.
• Package & Mounting: Surface-mount radial can (φ16 × 21.5 mm) in embossed carrier taping for automated placement; recommended PCB land size L:1.63 × W:1.63 cm supports straightforward assembly.
• Operating Temperature Range: Rated for −40°C to +85°C operation to accommodate a wide range of environmental conditions.

Typical Applications

• Automotive Power Systems: Bulk smoothing and decoupling on high-voltage rails in electronic control units, leveraging the 100 V rating and AEC-Q200 qualification.
• DC–DC Converters and Power Supplies: Output filtering and ripple suppression in converters where 220 µF at 100 V and defined ripple current capability improve regulation and transient response.
• Industrial Power Electronics: Energy storage and ripple filtering in industrial controllers and power modules that require robust lifetime at elevated temperatures.

Unique Advantages

• High-voltage bulk capacitance: 220 µF at 100 V delivers substantial energy storage in a compact SMD can, reducing the need for multiple lower-voltage capacitors in series.
• Measured ripple performance across frequencies: Specified ripple currents at 120 Hz and 10 kHz support reliable filtering in both low- and high-frequency switching environments.
• AEC-Q200 qualification: Enables use in automotive-grade designs where recognized component-level stress testing is required.
• Defined thermal endurance: 2000 hours at 85°C gives a clear, application-relevant lifetime metric for thermal and reliability planning.
• SMD-ready packaging: Embossed carrier taping and a standard land-size recommendation simplify automated assembly and PCB layout integration.
• Controlled loss and leakage: Low tanδ (0.08 at rated voltage) and specified leakage current assist in thermal budgeting and hold-up time design.
