Product details

AEC-Q100 qualification makes this part suitable for under-hood automotive electronics, where the MEMS resonator's inherent shock and vibration tolerance outperforms quartz in harsh environments. The 2.25V to 3.6V supply range allows it to run from a 2.5V or 3.3V rail without an extra regulator, simplifying the power tree on mixed-voltage boards.

Package, enable function, and power budget

Housed in a 6-SMD no-lead package measuring 3.20mm x 2.50mm, with a seated height of 0.90mm — a compact footprint that fits space-constrained ECU and sensor module layouts.

Frequently asked questions

Is DSC1121CL2-033.3333T AEC-Q100 qualified?

Yes, it carries AEC-Q100 rating, making it qualified for automotive applications including under-hood environments. The MEMS resonator base adds shock and vibration tolerance beyond typical quartz oscillators.
