Crystals Procurement Notes

Verify the specific suffix 'IAT' against manufacturer documentation to confirm tape-and-reel packaging and exact thermal specifications. Ensure compatibility with existing PCB footprint dimensions of 2.00mm by 1.60mm. Cross-reference the 10pF load capacitance requirement with the target oscillator circuit design to guarantee frequency accuracy and proper startup conditions.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency is required with tight ±10 ppm tolerance. The 10pF load capacitance dictates circuit matching requirements. Consider the 4-SMD no-lead form factor for automated assembly processes. Evaluate the 60 Ohm ESR against oscillator amplifier drive levels to prevent overdriving or failure to start.
