That means it keeps running in an engine bay on a summer day or inside a satellite in LEO — environments where a standard quartz XO would drift out of spec or stop oscillating altogether. ## AEC-Q100 Grade 1 — automotive and industrial deployment It is suited for engine-control units, transmission controllers, and chassis-domain ECUs where the ambient temperature hits 105°C and the junction sees 125°C. The wide supply range of 2.25V to 3.6V lets it run directly from a 3.3V or 2.5V rail — no extra LDO needed. Microchip lists the DSC1121AM1-033.0000T as Active. The 6-SMD, No Lead Exposed Pad package measures 7.00mm x 5.00mm with a seated height of 0.90mm.","metaTitle":"DSC1121AM1-033.0000T MEMS XO – 33 MHz, AEC-Q100","metaDescription":"Microchip DSC1121AM1-033.0000T: 33 MHz MEMS XO, CMOS output, ±50 ppm stability, AEC-Q100, -55°C to 125°C.
