Crystals Procurement Notes

Verify the specific suffix 'IJR' against the manufacturer's current production status, as availability may vary by region or distributor. Confirm that the 9pF load capacitance matches the target circuit design requirements before procurement. Ensure the selected supplier provides valid traceability documentation for compliance purposes.

Crystals Selection Notes

Select this component when a 19.2 MHz fundamental frequency with ±10ppm tolerance is required. The 9pF load capacitance must align with the oscillator circuit's capacitive load calculations. Consider the 120 Ohm ESR value for drive level sensitivity. The 4-SMD package size dictates PCB layout constraints regarding pad spacing and thermal relief.
