Crystals Procurement Notes

Verify the specific suffix 'IJR' against official CTS documentation to confirm the 9pF load capacitance specification, as variations exist within the 402 series. Confirm current availability status directly with the manufacturer or authorized distributors, as supply conditions may change. Ensure the selected variant matches the required ESR and temperature range for the target application environment.

Crystals Selection Notes

Select this component when a 26 MHz fundamental crystal with 9pF load capacitance is required. Compare the 100 Ohm ESR against the oscillator circuit's drive level requirements to ensure stability. Verify that the 4-SMD 2016 footprint aligns with the PCB layout constraints and that the -40°C to +85°C range meets the operational thermal specifications.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series offers various load capacitances and packages. The 402F2601XIJR specifically denotes the 26 MHz frequency, 9pF load, and IJR packaging configuration. It is designed for general-purpose timing applications requiring high stability in a small form factor.

Crystals Replacement Considerations

The 402F2601XIAR is listed as a similar alternative by the manufacturer. Verify if the AR suffix indicates a different load capacitance or package variation before substitution. Cross-reference technical parameters to ensure electrical compatibility.
