Crystals Procurement Notes

Verify the specific ordering suffix to confirm exact frequency tolerance and load capacitance requirements. Ensure the selected variant matches the required operating temperature range for the target application. Confirm that the 4-SMD package dimensions are compatible with the PCB footprint and assembly process capabilities. Check for RoHS3 compliance documentation if environmental regulations apply to the end product.

Crystals Selection Notes

Select this component based on the required 27 MHz operating frequency and ±30 ppm stability. Consider the 8 pF load capacitance requirement when designing the oscillator circuit to ensure accurate frequency performance. Evaluate the 100 Ohm maximum ESR against the oscillator driver strength. Verify that the SMD package size fits within the spatial constraints of the design.
