Housed in a 6-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm — a standard footprint that places without tombstoning risk on a typical reflow profile.","metaTitle":"DSC1121CM1-012.0000T MEMS XO 12 MHz CMOS -55°C to 125°C","metaDescription":"Microchip DSC1121CM1-012.0000T MEMS oscillator, 12 MHz CMOS output, ±50ppm stability, 2.25V-3.6V supply, -55°C to 125°C.
