UUB1A221MNL1GS

The UUB1A221MNL1GS is a chip-type aluminum electrolytic capacitor from Nichicon’s UUB series designed for high-temperature, high-reliability applications. It is a surface-mount, radial can SMD capacitor with a rated capacitance of 220 µF at 10 V, intended for automated assembly via carrier tape.

Built for extended operation at elevated temperatures, this part is specified for an operating range of −40 °C to +125 °C, is AEC-Q200 qualified, and is RoHS compliant—making it suitable for demanding automotive and industrial environments.

Key Features

• Temperature Range & Reliability — Rated for operation from −40 °C to +125 °C with an endurance specification of 2000 hours at 125 °C (when restored to 20 °C after test).
• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 10 V and a capacitance tolerance of ±20% at 120 Hz, 20 °C.
• Package & Mounting — Chip-style radial can in an SMD package, compatible with automated mounting using carrier tape; recommended PCB land size: 8.3 mm × 8.3 mm; physical size L: 1.0 cm × D: 0.8 cm.
• Ripple Handling — Specified ripple currents of 90 mA at 120 Hz and 135 mA at 10 kHz provide defined performance for low- and high-frequency ripple conditions.
• Leakage and Dissipation Characteristics — Leakage current for rated voltages 10–50 V is specified as not more than 0.03 × C × V (µA) after 1 minute’s application at 20 °C; tan δ (loss tangent) at 120 Hz, 20 °C is specified up to 0.32 for 10 V parts.
• Manufacturing & Assembly Robustness — Designed to withstand soldering heat (hot plate at 250 °C for 30 seconds) while meeting post-process electrical requirements; applicable to automatic mounting via carrier tape.
• Standards & Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronics — AEC-Q200 qualification and a −40 °C to +125 °C operating range make this capacitor suitable for board-level energy storage and filtering in automotive modules.
• Power management modules — 220 µF at 10 V combined with defined ripple current ratings supports smoothing and local energy buffering on low-voltage power rails.
• High-temperature industrial equipment — Engineered endurance of 2000 hours at 125 °C and soldering-heat resistance enable use in elevated-temperature industrial controls and power assemblies.

Unique Advantages

• AEC-Q200 Qualification: Provides a documented reliability baseline for automotive-grade applications and environments requiring rigorous component screening.
• High-temperature endurance: 2000 hours at 125 °C endurance rating supports long-term operation in hot ambient conditions, reducing the need for overspecifying components.
• Compact SMD form factor: Chip-type radial can with a small footprint (L: 1.0 cm × D: 0.8 cm) and 8.3 mm × 8.3 mm recommended land pattern enables dense board layouts and automated assembly.
• Measured ripple performance: Defined ripple current ratings at 120 Hz and 10 kHz allow predictable behavior in both low- and high-frequency power circuits.
• Manufacturing-ready: Designed for carrier-tape feeding and proven soldering-heat resistance to streamline pick-and-place and reflow/solder processes.
• Regulatory compliance: RoHS conformity simplifies end-product regulatory tracking and environmental compliance.
