Crystals Procurement Notes

Verify the specific suffix 'DR' against official CTS documentation to confirm tape and reel packaging specifications. Ensure the design-in process accounts for the 18pF load capacitance requirements of the host circuit. Cross-reference the 100 Ohm ESR limit with the oscillator circuit's drive level constraints to prevent frequency instability or aging issues during operation.

Crystals Selection Notes

Select this component when a 26 MHz fundamental crystal with 18pF load capacitance is required. The 402 series provides a balance of size and performance for general-purpose timing. Consider the ±10 ppm tolerance for systems requiring moderate frequency accuracy. The wide temperature range makes it suitable for industrial or automotive environments where standard commercial grade parts may fail.

Crystals Part Context

This part belongs to the CTS 402 series of low-profile crystals. The series is characterized by small footprints and leadless packages optimized for high-volume SMT production. The 402F2601XIDR specifically targets applications needing reliable 26 MHz reference frequencies in space-constrained designs.

Crystals Replacement Considerations

The 402F2601XIAR is listed as a similar alternative from the same manufacturer. Verify if the 'AR' suffix denotes a different packaging type or minor parameter variation before substitution.
