Crystals Procurement Notes

Verify the specific suffix 'IAT' against official CTS documentation to confirm lead time and availability status, as distributor listings may vary. Ensure compatibility with existing PCB footprints and reflow profiles. Cross-reference the 10pF load capacitance requirement with the target circuit design to guarantee accurate frequency performance under operational conditions.

Crystals Selection Notes

Select this component when a 26 MHz fundamental frequency with ±20ppm stability is required in a compact SMD form factor. The 10pF load capacitance dictates specific oscillator circuit design parameters. Consider the hermetic seal for environmental protection and the 100 Ohm ESR for driving level limitations within the host application's oscillator topology.
