Crystals Procurement Notes

Verify the specific suffix 'CJT' corresponds to tape-and-reel packaging when ordering. Confirm that the 9pF load capacitance matches the oscillator circuit design requirements. Ensure the ±30ppm tolerance aligns with system timing accuracy needs. Check for any lead-time variations due to manufacturing schedules.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency is required in a small SMD form factor. Compare ESR values against oscillator drive level specifications to prevent over-driving. Consider thermal stability requirements within the -20°C to +70°C range for industrial or consumer electronics environments.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series provides various frequencies and package sizes optimized for modern electronics. The 402F variant specifically denotes a 2.0mm x 1.6mm footprint, balancing size and performance for portable devices.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz crystals with identical 9pF load capacitance and similar ESR. Verify pin compatibility and physical dimensions before swapping. Cross-reference with manufacturer-approved alternative part numbers for supply chain resilience.
