Active draw is 27 mA typical at 40 MHz, which is the current into the output buffer driving a CMOS load; the MEMS core itself draws far less. Housed in a 6-VDFN measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm — the 0.197\" × 0.126\" footprint matches industry-standard 5×3.2 mm oscillator pads, so it drops onto existing layouts without a board spin.","metaTitle":"DSC1201BA3-40M00000T MEMS XO 40 MHz CMOS ±20 ppm -40°C to","metaDescription":"Active Microchip XO (Standard) with MEMS resonator, 40 MHz, CMOS output, ±20 ppm stability, 2.25-3.63 V supply, standby mode, -40°C to 125°C.
