The -20°C to 70°C operating range limits it to passenger compartment or climate-controlled enclosures; for engine-bay exposure you would need the wider -40°C to 125°C variant in the same series. ## Power budget and standby control Max supply current is 7.2 mA at 42.5 MHz, low enough for a battery-powered telematics module or an always-on sensor hub. Supply voltage range is 1.8V to 3.3V, covering the common digital rails without an external level translator. The 4-SMD, No Lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard MEMS oscillator footprint that fits most 4-pin clock layouts.","metaTitle":"DSC1001CE2-042.5000 Microchip MEMS Oscillator – 42.5 MHz","metaDescription":"Microchip DSC1001CE2-042.5000 XO (Standard) MEMS oscillator, 42.5 MHz CMOS output, ±25 ppm stability, AEC-Q100 qualified.
