Crystals Procurement Notes

Verify the specific suffix 'I' indicates the extended industrial temperature range (-40°C to +85°C) compared to commercial variants. Confirm that the 13pF load capacitance matches the target oscillator circuit design requirements. Ensure the 4-SMD package dimensions align with the PCB land pattern specifications to prevent soldering defects during reflow processes.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency is required with strict ±30ppm tolerance. The 50 Ohm ESR specification must be compatible with the driving circuit's gain capabilities. Consider the 13pF load capacitance requirement for accurate frequency matching in the final application environment.
