Crystals Procurement Notes

Verify the specific suffix designation to ensure correct load capacitance and tolerance specifications match the target circuit requirements. Confirm that the 4-SMD package dimensions align with the printed board layout constraints. Ensure compliance with RoHS directives if required by the final product regulations. Cross-reference the manufacturer datasheet for handling precautions related to surface mount components.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required with ±15 ppm stability. The 8 pF load capacitance must match the oscillator circuit design parameters. Consider the 60 Ohm ESR value for impedance matching within the system. The compact SMD form factor is suitable for space-constrained applications requiring reliable timing signals.

Crystals Part Context

This part belongs to the 402 series of crystals from CTS-Frequency Controls. The series offers various frequencies and packages for general-purpose timing applications. The 402F374XXCKR specifically addresses needs for 37.4 MHz operations in surface mount environments. It serves as a passive frequency control element distinct from active oscillators.

Crystals Replacement Considerations

The 402F374XXCJT is a documented alternative with identical frequency but a 9 pF load capacitance. Verify circuit compatibility before substitution due to the capacitance difference.
