What the AEC-Q100 rating means for your BOM
The DSC6001HI2A-006.1400: This MEMS oscillator carries AEC-Q100 qualification, covering the -40 °C to +85 °C industrial-automotive temperature band. The 1.71 V to 3.63 V supply range lets it run from a 1.8 V MCU rail or a 3.3 V system rail without a level translator — one BOM line covers both voltage domains.

4-SMD, No Lead package measuring 1.60 mm x 1.20 mm with a seated height of 0.89 mm. The 0.50 mm pitch land pattern requires a solder-paste stencil aperture sized for the pad geometry — the small body limits the decoupling capacitor placement to the outer board area.
