Crystals Procurement Notes

Verify the specific suffix 'CJT' against the official CTS datasheet to confirm the 9 pF load capacitance and 60 Ohm ESR specifications. Ensure the ordering part number matches the required frequency tolerance of ±10 ppm. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly. Cross-reference the package dimensions with PCB footprint libraries to ensure mechanical compatibility.

Crystals Selection Notes

Select this component when a compact SMD crystal with 9 pF load capacitance is required for 38.4 MHz applications. The ±10 ppm tolerance provides higher precision than standard ±15 ppm parts. Consider the 60 Ohm ESR for circuit drive level calculations. Verify that the -20°C to +70°C temperature range meets the operational environment requirements of the target application.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series offers various load capacitances and package sizes. The 402F384XXCJT specifically denotes the 38.4 MHz frequency variant with CJT packaging characteristics. It is distinct from other series like the 416 series which may have different physical dimensions or electrical parameters.

Crystals Replacement Considerations

Direct substitutes must match the 38.4 MHz frequency, 9 pF load capacitance, 4-SMD no-lead package, and similar ESR values. Check manufacturer cross-reference lists for pin-compatible alternatives with identical electrical specifications.
