The 6-SMD No Lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — it is a standard MEMS oscillator footprint compatible with common 3.2 x 2.5 mm XO pads. The No Lead construction means no exposed side pads; the solder joint is visible only underneath the device, so X-ray inspection is the standard post-reflow check.","metaTitle":"DSC1121CI2-066.0000 MEMS Oscillator 66 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121CI2-066.0000 XO, 66 MHz, CMOS output, ±25 ppm stability, AEC-Q100 qualified, -40°C to 85°C, active production.
