Maximum supply current is 35 mA when enabled, dropping to 22 mA when disabled — useful for power-sensitive designs that gate the clock during sleep modes. ## Package and footprint for board layout Housed in a 6-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, this oscillator fits tight PCB real estate. The no-lead construction means the solder joints are under the package — ensure the PCB land pattern matches the recommended footprint for proper fillet formation and inspectability. ## Active production — no end-of-life pressure It is suitable for both new designs and ongoing production builds.","metaTitle":"DSC1121DM2-040.0000T MEMS Oscillator – 40 MHz CMOS, AEC-Q100","metaDescription":"Microchip DSC1121DM2-040.0000T: 40 MHz XO, CMOS output, AEC-Q100, -55 to +125°C, 2.25-3.6V supply.
