The AEC-Q100 rating places it in the automotive-grade component class, suitable for under-hood and chassis-domain applications where temperature cycling and vibration exceed commercial-grade limits. The Enable/Disable function allows the output to be tri-stated, reducing supply current from 35 mA max active to 22 mA max disabled — useful for power-cycled subsystems in multi-rail designs. ## Package and mounting for production 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 DSC1121CI2-125.0000 fits standard reflow profiles for surface-mount assembly. The 0.126\" x 0.098\" footprint is compatible with common 6-pin oscillator land patterns; no via-in-pad or special fan-out is required for the CMOS output. Sourced through independent distribution — quoted to order against the BOM quantity. No pin-compatible second source is listed, but the MEMS resonator construction provides inherent shock tolerance beyond quartz-based alternatives.","metaTitle":"DSC1121CI2-125.0000 MEMS Oscillator – 125 MHz, AEC-Q100","metaDescription":"Microchip DSC1121CI2-125.0000 XO (Standard) MEMS oscillator, 125 MHz CMOS output, AEC-Q100 qualified, -40°C to 85°C, 2.25V-3.6V supply.
