The DSC1003BE2-012.0000 is an active-production MEMS-based XO from Microchip, rated AEC-Q100 — the automotive-grade qualification that covers -20°C to +70°C ambient operation and the reliability stress tests required for under-hood and cabin electronics. It delivers a 12 MHz CMOS output with ±25 ppm frequency stability, running from a 1.7V to 3.6V supply rail — the wide voltage range lets it share a rail with 1.8V or 3.3V logic without an extra regulator.
Standby power-down — 15 µA disable current for battery-backed designs
For a telematics module or sensor node that clocks most of its life in sleep, that 15 µA leakage is below the self-discharge of a small coin cell — the oscillator does not drain the backup battery.
4-SMD no-lead package — surface-mount layout fit
Housed in a 4-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, it fits standard 5x3.2 mm XO footprints — a drop-in replacement for quartz oscillators in that form factor.
