Housed in a 6-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, the footprint matches standard 3.2x2.5mm oscillator pads — a direct drop-in for many quartz XO layouts. Surface-mount assembly with no lead formed under the package; the 6-pad layout includes two no-connect or ground pads that improve mechanical stability during reflow. RoHS compliance is standard for the series; confirm at RFQ if a specific certificate is required.","metaTitle":"DSC1121CM1-018.0000T MEMS Oscillator","metaDescription":"Microchip DSC1121CM1-018.0000T XO (Standard), 18 MHz CMOS output, 2.25-3.6V supply, -55 to 125°C.
