UWT1C221MCL1GS

The UWT1C221MCL1GS is a chip-type aluminum electrolytic capacitor from Nichicon's UWT series, designed for surface mounting on high-density printed circuit boards. It delivers 220 µF capacitance at a 16 V rating and is polarized for DC applications.

Built for demanding environments, this component operates across a wide temperature range (−55 °C to +105 °C), is AEC-Q200 qualified, and is compliant with RoHS directives—making it suitable for automotive and other temperature-critical surface-mount assemblies that require automatic placement with carrier tape.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Wide Operating Temperature — Specified for operation from −55 °C to +105 °C to support temperature‑extreme environments.
• AEC-Q200 Qualified & RoHS Compliant — Meets AEC-Q200 qualification and RoHS directives (2011/65/EU, (EU)2015/863) as noted in the product data.
• Chip‑Type Surface Mount — Chip-style SMD can package designed for high-density PCBs and compatible with automatic mounting machines fed with carrier tape.
• Compact footprint — Size dimension L: 7.7 × D: 6.3 mm with recommended land pattern L: 6.6 × W: 6.6 mm for surface mount layouts.
• High‑temperature endurance — Rated endurance of 1000 hours at 105 °C per the series specifications.
• Ripple current performance — Specified ripple current of 105 mA at 120 Hz and 157.5 mA at 10 kHz for AC stress considerations.
• Low leakage — Leakage current specification: after 2 minutes at rated voltage and 20 °C, not more than 0.01CV or 3 µA (whichever is greater), per the datasheet.

Typical Applications

• Automotive systems — AEC‑Q200 qualified and specified for −55 °C to +105 °C operation, suitable for automotive electronic modules where SMD electrolytic capacitance is required.
• High‑density PCB assemblies — Chip‑type SMD can intended for surface mounting on densely populated boards and compatible with automatic placement from carrier tape.
• Temperature‑critical electronics — Specified endurance of 1000 hours at 105 °C supports use in environments with sustained elevated temperatures.

Unique Advantages
