Procurement Notes

Verify the specific suffix 'MDII' against official QST documentation to confirm exact tolerance and temperature range specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Cross-reference part numbers carefully as suffix variations may indicate different electrical parameters or packaging options not covered by generic listings.

Selection Notes

Select this component when a 26 MHz fundamental frequency is required with ±30 ppm stability. Consider the 8 pF load capacitance requirement for circuit design matching. Evaluate the 90 Ohm ESR against oscillator amplifier capabilities. The 4-SMD package dictates board layout constraints and assembly method selection.
