Crystals Procurement Notes

Verify the specific suffix 'CDR' against official CTS documentation to confirm tape and reel packaging specifications. Confirm that the 60 Ohm ESR and 18pF load capacitance align with the target circuit design requirements. Check current availability status as distribution channels may list discontinued or limited stock items. Ensure compliance with RoHS3 standards if required by the final assembly regulations.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required with moderate stability. The 18pF load capacitance must match the oscillator circuit's external capacitor values. Consider the 60 Ohm ESR limit for drive level sensitivity. The small 2.00mm x 1.60mm footprint suits space-constrained PCB layouts requiring surface mount technology.

Crystals Part Context

This part belongs to the CTS 402 Series of miniature crystals. The series offers various frequencies and packages optimized for high-volume surface mount production. The 402F37433CDR specifically targets applications needing a standard 37.4 MHz reference in a compact form factor.

Crystals Replacement Considerations

Direct substitutes include other 37.4 MHz crystals with matching 18pF load capacitance and similar ESR. Verify package dimensions and pin compatibility before substitution. Alternative parts from other manufacturers must meet the same electrical specifications.
