Housed in a 6-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The no-lead footprint requires a solder-paste stencil with aperture matching the pad geometry; no through-hole alignment needed.","metaTitle":"DSC1121CL2-050.0000T – Microchip MEMS XO, 50 MHz, AEC-Q100","metaDescription":"Microchip DSC1121CL2-050.0000T: 50 MHz XO (Standard), CMOS output, ±25 ppm stability, -40°C to 105°C, AEC-Q100 qualified.
