Procurement Notes

Verify the manufacturer designation as TXC Corporation when sourcing this component from distributors like QST or Mouser. Confirm that the part number suffix corresponds to the specific tape and reel packaging quantity of 1000 units. Ensure the requested frequency matches the 8.192 MHz specification exactly, as variations exist within the QTM750 series.

Selection Notes

Select this model when a compact 7x5mm footprint is required for space-constrained designs. Choose based on the need for fast start-up times compared to traditional quartz solutions. Consider the ±50ppm stability requirement against system timing tolerances before finalizing the component choice.

Part Context
