12 MHz MEMS XO — AEC-Q100 and industrial temp range
The DSC1001BI2-012.0000T is a 12 MHz MEMS-based oscillator from Microchip's DSC1001 series, delivering a CMOS output with ±25 ppm frequency stability across -40°C to +85°C. The AEC-Q100 qualification makes this part a direct fit for automotive ECUs, ADAS camera modules, and engine-bay sensors where quartz crystals risk failure under sustained vibration. The MEMS resonator inherently withstands higher shock and acceleration than a quartz blank — the laser etch on the package lid should trace cleanly to Microchip's assembly lot if you're verifying provenance.
At 6.3 mA max active current, the thermal load in the 5.0×3.2 mm 4-SMD no-lead package is minimal, keeping the junction well below the 85°C ceiling.
