Crystals Procurement Notes

Verify the specific suffix 'E' against official datasheets to confirm the exact load capacitance and temperature rating, as variations exist within the 403 series. Confirm that the 3.2x2.5mm package matches the design requirements. Ensure the ±30ppm tolerance aligns with the target circuit's phase noise and jitter specifications before finalizing procurement.

Crystals Selection Notes

Select this component when a standard 14.31818 MHz reference is required in a small SMD form factor. Compare ESR values against the oscillator circuit's drive level constraints to prevent over-driving the crystal. Verify that the -20°C to +70°C industrial temperature range meets the operational environment requirements of the end product.
