Crystals Procurement Notes

Verify that the specific suffix 'MEHV' matches the required tape-and-reel packaging configuration and lead-free compliance standards mandated by the target manufacturing process. Confirm that the 40 MHz fundamental mode aligns with the host circuit's input impedance requirements. Ensure the selected variant meets the specific automotive or industrial qualification standards applicable to the end product.

Crystals Selection Notes

Select this component when a compact, robust timing solution is required for harsh environments. The 4-pin CSMD form factor supports high-volume surface mounting processes. The specified stability parameters suit applications demanding consistent clock signals under varying thermal conditions without requiring active temperature compensation.

Crystals Part Context

This part belongs to the QT252S series of seam-sealed quartz crystals. These components are designed to replace through-hole equivalents in modern miniaturized electronics. The series offers improved reliability compared to standard epoxy-sealed packages, making them suitable for applications subject to mechanical stress or humidity exposure.

Crystals Replacement Considerations

The TXC Corporation part number QT252S-40.000MEIV-T serves as a verified substitute. Both parts share identical electrical specifications, including the 40 MHz frequency, 8 pF load capacitance, and ±10 ppm tolerance. Verify pin compatibility and reflow soldering profiles before implementation.
