Procurement Notes

Verify the specific suffix 'MBD' against official QST documentation to confirm the exact pinout, tolerance, and load capacitance specifications. Ensure the selected variant matches the required supply voltage and output drive strength for the target application circuit design.

Selection Notes

Select this component when a 33 MHz CMOS clock source is required with ±25ppm stability. Confirm that the 3.2mm x 2.5mm surface mount footprint fits the PCB layout constraints. Validate that the -40°C to 85°C industrial temperature range meets the environmental requirements of the end product.

Part Context

This part belongs to the QTM325 series of standard oscillators from QST. The series offers various frequencies and packages. This specific model provides a fixed 33 MHz output with enable functionality, distinguishing it from non-enable variants or different frequency options within the same family.

Replacement Considerations

QTM325-33.000MDE-T is a documented alternative within the QST portfolio, sharing similar mounting and temperature characteristics but potentially differing in electrical parameters or packaging details as indicated by the suffix change.
