Crystals Procurement Notes

Verify current availability status as the part may be discontinued or subject to long lead times. Confirm that the specific suffix IJT matches the required tape and reel packaging configuration. Ensure the 9pF load capacitance aligns with the target circuit design requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency with ±20ppm tolerance is required. The 60 Ohm ESR and 9pF load capacitance must match the oscillator circuit specifications. Consider the 4-SMD 2x1.6mm footprint for PCB layout constraints and verify the -20°C to 70°C temperature range suffices for the application environment.

Crystals Part Context

This crystal belongs to the CTS 402 series of surface-mount devices. The series offers various frequencies and package sizes optimized for space-constrained electronics. The 402F40022IJT specifically provides a standard 40 MHz output suitable for digital logic timing applications requiring moderate stability.

Crystals Replacement Considerations

Cross-reference with other 40 MHz SMD crystals from CTS or competitors having identical 9pF load capacitance and similar ESR values. Verify package dimensions and pin compatibility if substituting with different manufacturers' components.
