Crystals Procurement Notes

Verify the specific load capacitance requirements of the target circuit against the 18 pF specification. Confirm that the PCB footprint matches the 4-SMD No Lead package dimensions. Ensure the operating environment stays within the -20°C to +70°C range to maintain the stated ±15 ppm stability. Check RoHS compliance status if required by project regulations.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required in a compact surface-mount form factor. The 60 Ohm ESR value should be compatible with the oscillator circuit's drive level constraints. Consider the ±15 ppm tolerance for applications requiring moderate frequency accuracy. Evaluate the 4-SMD package size against available board space constraints.

Crystals Part Context

This part belongs to the 402 Series of crystals from CTS-Frequency Controls. The series provides various standard frequencies in small SMD packages. The 402F374XXCDR specifically addresses the need for 37.4 MHz timing in consumer electronics and industrial control systems where space efficiency is critical.

Crystals Replacement Considerations

Direct substitutes must match the 37.4 MHz frequency, 18 pF load capacitance, 60 Ohm ESR, and 4-SMD No Lead package. Verify that alternative manufacturers offer components with identical dimensional tolerances and electrical characteristics to ensure pin-to-pin compatibility.
