Crystals Procurement Notes

Verify the specific suffix CAT against official CTS documentation to confirm tape and reel packaging specifications. Ensure the load capacitance requirement of 10pF matches the target circuit design. Cross-reference the ESR value of 80 Ohms with oscillator driver strength capabilities. Confirm that the 4-SMD no-lead footprint aligns with the board layout silkscreen and solder mask definitions prior to procurement.

Crystals Selection Notes

Select this component when a 30 MHz timing source with ±30 ppm stability is required for space-constrained applications. The 10pF load capacitance dictates compatibility with specific oscillator circuits. The 80 Ohm ESR must be supported by the driving gate to ensure reliable oscillation start-up. Evaluate the 4-SMD no-lead package against available PCB real estate and thermal management requirements for the final assembly.

Crystals Part Context

This part belongs to the 402F series of surface-mount crystals from CTS-Frequency Controls. The series offers various frequencies and package sizes optimized for high-volume manufacturing. The 402F designation indicates a specific footprint and mounting style distinct from through-hole or larger SMT variants. This model represents a standard frequency point within the product line.

Crystals Replacement Considerations

Direct substitutes include other 30 MHz crystals with identical 10pF load capacitance and 4-SMD no-lead footprints. Verify that alternative parts meet the same ±30 ppm stability and 80 Ohm ESR specifications. Check for pinout compatibility if using different manufacturers' components. Ensure the replacement maintains the same operating temperature range as defined in the original datasheet.
