Active draw is 6.5 mA max at 12.7281 MHz, typical for a MEMS oscillator at this frequency. ## Package and footprint for 4-VDFN Housed in a 4-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm max. The 0.197\" x 0.126\" footprint is a standard MEMS oscillator land pattern — no via-in-pad required. Surface-mount assembly with a standard reflow profile; the package is compatible with lead-free soldering processes. Availability confirmed at RFQ.","metaTitle":"DSC1001BI3-012.7281T MEMS Oscillator – 12.7281 MHz, AEC-Q100","metaDescription":"DSC1001BI3-012.7281T: Microchip Technology MEMS XO, 12.7281 MHz, ±20 ppm, CMOS output, 1.7V–3.6V supply, AEC-Q100 qualified, -40°C to +85°C.
