Rated AEC-Q100, it carries the automotive qualification that standard commercial oscillators do not — for under-hood or cabin electronics where the board sees thermal cycling and mechanical stress. ## Supply voltage and standby current for battery-powered nodes The 1.7V to 3.6V supply range lets this oscillator run directly off a 1.8V, 2.5V, or 3.3V rail without a separate LDO — one less component on the BOM. With the Standby (Power Down) function enabled, the supply current drops to 15 µA max — the oscillator sleeps with the rest of the system and wakes on a logic-level pin, saving battery life in intermittently powered modules. ## Temperature range and frequency stability for indoor electronics The -20°C to 70°C operating range covers indoor, office, and appliance environments — not engine-bay or outdoor pole-mount. The ±25 ppm frequency stability holds the clock tight enough for CAN, USB, and most MCU crystal-less designs. Sourced to order against the BOM quantity; availability confirmed at RFQ.","metaTitle":"DSC1003BE2-012.0000T MEMS Oscillator 12 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1003BE2-012.0000T XO (Standard) 12 MHz CMOS output, ±25 ppm stability, 1.7V-3.6V supply, AEC-Q100 qualified.
