Crystals Procurement Notes

Verify the specific suffix D18 against the manufacturer's datasheet to ensure correct packaging and tape-and-reel configuration. Confirm that the 40 Ohm ESR and 18pF load capacitance match the target circuit design requirements. Check for RoHS3 compliance documentation if required by project standards. Ensure the operating temperature range of -20°C to +70°C is sufficient for the intended application environment before finalizing procurement.

Crystals Selection Notes

Select this component when a 24.576 MHz fundamental frequency is required with tight ±20ppm tolerance. The 40 Ohm ESR value must be compatible with the oscillator circuit's drive level constraints. The 7.0x5.0mm footprint should be evaluated against available PCB space compared to smaller or larger alternatives. Consider the -20°C to +70°C industrial temperature range suitability for the operational environment.

Crystals Part Context

This part belongs to the CX5 series of quartz crystals from Cardinal Components Inc., designed for general-purpose timing applications. The series offers various frequencies within the 7.3728 MHz to 48.000 MHz range.
