Product details

MEMS resonator, automotive-qualified clock source

Supply voltage and power-tree fit

Operating from 2.25V to 3.6V, this oscillator spans 2.5V and 3.3V logic rails without an intermediate regulator — one less part in the power tree for an automotive body controller or industrial PLC.

Package, footprint, and reflow considerations

Housed in a 6-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm — a standard footprint that places without tombstoning risk on a typical lead-free reflow profile. Surface-mount with no exposed thermal pad; the small body and 0.90mm height fit well under low-profile enclosures in automotive or industrial assemblies.

Frequently asked questions

Is the DSC1121BI2-040.0000 AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, which means it has passed automotive-grade stress tests including temperature cycling, ESD, and latch-up. Suitable for under-hood and cabin applications.

What is the closest pin-compatible alternative to the DSC1121BI2-040.0000?

Within the DSC1121 series, other frequency variants share the same 6-SMD package and pinout. For a direct 40 MHz replacement, the base product number DSC1121 covers the family; confirm the stability and temperature grade match your BOM.
