Procurement Notes
Verify the complete part number including suffixes to ensure correct frequency and tolerance specifications. Confirm package compatibility with PCB footprint requirements. Check datasheet for operating temperature range limitations. Ensure storage conditions meet manufacturer guidelines to maintain component integrity prior to assembly.
Selection Notes
Select this component when a 40 MHz reference with ±30 ppm stability is required. Consider the 12 pF load capacitance requirement for circuit design matching. Evaluate the 50 ohm ESR against oscillator circuit drive level constraints. Compare physical dimensions against available board space for SMD placement.
Part Context
This part belongs to QST's QT216S series of surface-mount crystals. The series provides various frequency options within a standardized small form factor. The MAHE-T suffix indicates specific packaging and tolerance characteristics defined by the manufacturer for this particular variant.
Replacement Considerations
Direct substitutes include other 40 MHz crystals with identical 2x1.6mm footprint and ±30 ppm stability. Verify pinout and electrical parameters match before substitution. Cross-reference with similar packages from other manufacturers if supply chain constraints exist.
