Crystals Procurement Notes

Verify the specific suffix 'XIAR' matches the required tape-and-reel packaging configuration, as other suffixes may indicate different quantities or handling specifications. Confirm that the 10pF load capacitance aligns with the target circuit design requirements before procurement. Ensure compatibility with standard reflow soldering profiles for ceramic packages.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency with tight ±10ppm tolerance is required. The 100 Ohm ESR value must be compatible with the driving circuit's impedance matching capabilities. Consider the -40°C to +85°C industrial temperature range against the operational environment constraints of the final application.
