Crystals Procurement Notes

Verify the specific suffix MEHQ against official datasheets to confirm exact tolerance and temperature range parameters. Ensure compatibility with reflow soldering profiles defined by the manufacturer. Confirm RoHS compliance status through current documentation before integration into production lines.

Crystals Selection Notes

Select this component when a 40 MHz reference is required in a compact 2.5x2.0 mm footprint. Consider the 10 ppm tolerance requirement and 10 pF load capacitance matching the host circuit design. Evaluate thermal performance within the -40°C to +85°C operational window for environmental suitability.

Crystals Part Context

This part belongs to the 8Z series of seam seal crystals from TXC Corporation. These components are designed for applications requiring stable frequency references in space-constrained electronic assemblies. The series offers various frequency options within the same standardized package dimensions.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 2.5x2.0 mm package, and 10 pF load capacitance. Verify that alternative sources provide identical seam seal construction and frequency stability specifications to ensure electrical equivalence.
