Crystals Procurement Notes

Verify the specific suffix 'CKT' against official manufacturer documentation to confirm package and termination specifications. Ensure compatibility with existing PCB footprints, as surface-mount crystals require precise solder paste application. Confirm that the 8 pF load capacitance matches the oscillator circuit design requirements to maintain frequency accuracy. Check for updated availability status as distribution channels may vary.

Crystals Selection Notes

Select this component when a 30.72 MHz reference is required with moderate stability needs. The 8 pF load capacitance suits circuits with low parasitic capacitance. Consider the 80 Ohm ESR limit for oscillator drive level constraints. Verify that the -20°C to 70°C temperature range aligns with the operational environment. Compare against alternative packages if space constraints differ from the standard dimensions.

Crystals Part Context

This part belongs to the 402 Series of surface-mount crystals from CTS-Frequency Controls. The series offers various frequencies and load capacitances for general-purpose timing applications. The 402F30733CKT specifically addresses the need for compact, leaded-style footprint crystals in modern SMD designs, bridging traditional through-hole reliability with surface-mount convenience.

Crystals Replacement Considerations

Direct substitutes include other 30.72 MHz crystals with 8 pF load capacitance and similar ESR values. Verify package dimensions and pinout compatibility before substitution. Alternative manufacturers may offer equivalent performance with different temperature ranges or stability ratings.
