Housed in a 6-SMD No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, this oscillator fits standard reflow assembly and occupies a compact footprint on the PCB. Surface-mount mounting with no leads means the package sits flush on the board — no through-hole clearance needed, and the thermal path is through the pad directly to the PCB copper.","metaTitle":"DSC1121BI2-125.0000T MEMS Oscillator 125 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121BI2-125.0000T: 125 MHz XO, CMOS output, ±25 ppm stability, 2.25V to 3.6V supply, AEC-Q100 qualified, -40°C to 85°C.
