The DSC1004AI2-081.8180: AEC-Q100 qualification means it meets the reliability stress and temperature cycling requirements for automotive ECU applications — the 85°C ceiling covers cabin and most under-hood zones, though a 125°C grade would be needed for direct engine-bay mounting. Supply voltage spans 1.8V to 3.3V, so the same oscillator can be used across multiple power domains without a separate level translator.
Housed in a 4-SMD, no-lead exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. Surface-mount assembly with standard reflow profiles; the MEMS resonator is less sensitive to vibration than a quartz crystal, but the board-level decoupling cap (100 nF) should sit within 2 mm of the supply pin to keep the 10.5 mA max supply current clean.
