It carries AEC-Q100 qualification, making it suitable for automotive electronics that require documented reliability screening — engine control modules, transmission controllers, or infotainment clock trees that see under-hood or cabin temperature swings. ## Supply range and package fit Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails without an external regulator — one less part on the BOM for mixed-voltage designs. The 6-SMD no-lead package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard 7050 footprint that reworks cleanly under hot air if the pad layout follows the manufacturer's land pattern.","metaTitle":"DSC1121NE5-066.6660 MEMS XO 66.666 MHz CMOS AEC-Q100","metaDescription":"Active MEMS oscillator, 66.666 MHz, CMOS output, ±10 ppm stability, AEC-Q100 qualified. 2.25-3.6 V supply, 6-SMD package.
