Crystals Procurement Notes

Verify the specific suffix 'CKT' against official CTS documentation to confirm tape and reel packaging status. Confirm current availability as distribution channels may list discontinued or backorder statuses. Ensure the load capacitance requirement matches the target circuit design before procurement. Validate RoHS3 compliance requirements for the final assembly process.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental mode crystal is required for space-constrained designs. The 10 pF load capacitance must align with the oscillator circuit's external capacitor values. Consider the ±30 ppm tolerance for applications requiring moderate frequency accuracy. The 60 Ohm ESR specification should be compatible with the driving gate circuit's output impedance.

Crystals Part Context

This part belongs to the CTS 402 series of surface mount crystals. The series offers various frequencies and package sizes for general-purpose timing applications. The 402F37433CKT specifically addresses the need for a 37.4 MHz reference in standard SMD footprints. It complements other CTS frequency control products like oscillators and resonators.

Crystals Replacement Considerations

Direct substitutes must match the 37.4 MHz frequency, 10 pF load capacitance, 60 Ohm ESR, and 4-SMD (2x1.6mm) package. Verify that alternative manufacturers offer components with identical ±30 ppm tolerance and fundamental mode operation. Check for compatible mounting dimensions and soldering profiles to ensure mechanical interchangeability.
