UUB1C221MNL1GS

The UUB1C221MNL1GS is a chip-type aluminum electrolytic capacitor designed for surface-mount assembly. It provides 220 µF capacitance at a 16 V rating and is optimized for high-temperature environments up to +125 °C.

Its construction supports automatic mounting from carrier tape and AEC-Q200 qualification, making it suitable for high-reliability applications that require compact bulk capacitance and stable performance under elevated temperatures.

Key Features

• Capacitance and Voltage: 220 µF rated capacitance at 16 V for bulk smoothing and energy storage in low-voltage power rails.
• High Temperature Operation: Rated for operation from −40 °C to +125 °C with a specified endurance of 2000 hours at 125 °C.
• Reliability & Qualification: AEC-Q200 qualified and RoHS compliant, supporting use in designs that require automotive-grade reliability and environmental compliance.
• Surface-Mount Chip Package: Chip-type, radial can SMD package designed for automated mounting from carrier tape, with a recommended land size of 1.03 × 1.03 cm for PCB layout.
• Low Leakage & Stability: Leakage current at 20 °C after 1 minute is specified as ≤ 0.03 × C × V (µA) for 10–50 V ratings, and tan δ at 16 V is specified (max. 0.24), supporting predictable impedance and loss characteristics.
• Ripple Handling: Specified ripple current of 102 mA at 120 Hz and 153 mA at 10 kHz for handling AC ripple on DC rails.
• Tolerance & Temperature Behavior: Capacitance tolerance ±20% and low-temperature impedance behavior characterized down to −40 °C (impedance ratio Z(−40 °C)/Z(+20 °C) = 8 for 16 V rating).

Typical Applications

• Automotive Electronics: Bulk smoothing and decoupling in control modules and power supplies where AEC-Q200 qualification and high-temperature endurance are required.
• Industrial Power Supplies: Energy storage and ripple filtering on low-voltage rails subjected to elevated ambient temperatures.
• Telecommunications & Networking: Power rail stabilization in compact SMD designs that require reliable performance under continuous load and temperature stress.
• Embedded & Control Systems: Local energy storage and decoupling for DC-DC converters and microcontroller power domains in high-reliability assemblies.

Unique Advantages

• High-temperature endurance: Rated for operation up to +125 °C with 2000 hours endurance at that temperature, enabling deployment in thermally demanding environments.
• Automated assembly ready: Chip-type SMD format compatible with carrier-tape feed for streamlined pick-and-place processes and higher PCB assembly throughput.
• AEC-Q200 qualification: Qualification provides an added level of assurance for reliability-focused designs requiring industry-recognized stress screening.
• Predictable electrical behavior: Defined leakage current, tan δ, and low-temperature impedance characteristics help simplify design margining and power integrity analysis.
• Compact, board-friendly footprint: SMD radial can construction with defined PCB land size supports compact power designs and consistent board layout implementation.
• Environmental compliance: RoHS compliant for designs targeting regulatory and customer environmental requirements.
