Crystals Procurement Notes

Verify the specific suffix 'CKT' against official CTS documentation to confirm tape and reel packaging requirements. Confirm that the 8pF load capacitance matches the target circuit design. Check current availability status as distribution channels may list discontinued or backordered items. Ensure the operating temperature range meets the application environment specifications before procurement.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required with ±15ppm stability. The 8pF load capacitance must align with the oscillator circuit's total stray capacitance. Consider the 60 Ohm ESR for drive level limitations. The 4-SMD package is suitable for automated assembly processes requiring small form factors.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series offers various frequencies and package sizes optimized for space-constrained designs. The 402F374XXCKT specifically targets applications needing a 37.4 MHz reference with standard commercial temperature ranges.

Crystals Replacement Considerations

Direct substitutes within the 402 series include parts with identical electrical parameters but different suffixes indicating packaging variations, such as 402F374XXCJR. Verify that any replacement maintains the 8pF load capacitance and 60 Ohm ESR to ensure circuit compatibility.
