Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the package dimensions align with the target PCB layout constraints. Check for any RoHS compliance documentation if environmental regulations apply to the end product. Ensure the operating temperature range meets the system's thermal requirements.

Crystals Selection Notes

Select this component when a 20.5 MHz fundamental frequency is required in a compact surface-mount form factor. Consider the 18 pF load capacitance requirement for circuit design matching. Evaluate the ±30 ppm frequency tolerance against the system's timing accuracy needs. Verify that the commercial temperature range (-10°C to +60°C) is sufficient for the intended application environment.
