UCB1A221MNL1GS

The UCB1A221MNL1GS is a chip-type aluminum electrolytic capacitor from Nichicon’s UCB series, engineered for surface-mount assembly and automated carrier-tape placement. It delivers 220 µF at a 10 V rating with a compact radial can SMD package and is intended for high-temperature, long-life applications.

Key value propositions include long endurance at elevated temperature (7000 hours at +105°C), AEC-Q200 qualification for automotive electronics, and RoHS compliance for environmental regulatory requirements.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 10 V for bulk decoupling and energy storage on low-voltage rails.
• Long Thermal Endurance — Load life specified as 7000 hours at +105°C, offering sustained performance in high-temperature environments.
• AEC-Q200 Qualified — Meets AEC-Q200 qualification as stated in product data, supporting use in automotive electronic designs.
• Operating Temperature Range — Specified for −25 °C to +105 °C to cover a wide range of ambient conditions.
• Measured Ripple Capability — Ripple current ratings of 141 mA at 120 Hz and 211.5 mA at 10 kHz for AC stress handling on power rails.
• Surface-Mount, Carrier-Tape Compatible — Chip-type radial can SMD package designed for automatic mounting machines fed with carrier tape.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Compact Footprint — Physical dimensions L: 10 mm × D: 8 mm (approx. 1.0 × 0.8 cm) with recommended land size L: 8.3 × W: 8.3 mm for PCB layout.

Typical Applications

• Automotive Electronic Systems — Suitable for use in automotive modules where AEC-Q200 qualification and long life at elevated temperatures are required.
• Power Rail Decoupling — Bulk decoupling and smoothing on 10 V supply lines, supported by 220 µF capacitance and specified ripple current ratings.
• High-Temperature Electronics — Systems operating up to +105 °C that require capacitors with proven 7000-hour endurance at that temperature.

Unique Advantages

• Extended High-Temperature Life: 7000-hour load life at +105 °C reduces replacement frequency in thermally demanding designs.
• Automotive-Grade Qualification: AEC-Q200 qualification supports integration into automotive-grade assemblies and design flows.
• Automated Assembly Ready: Carrier-tape compatible chip package simplifies pick-and-place handling for high-volume production.
• Clear Electrical Margining: Specified ripple currents at 120 Hz and 10 kHz enable designers to size margins for AC stress on power rails.
• Regulatory Compliance: RoHS compliance simplifies environmental approval and procurement requirements.
