Crystals Procurement Notes

Verify the specific suffix 'I' confirms the extended industrial temperature range (-40°C to +85°C) against the standard commercial variant. Ensure the load capacitance requirement of the target oscillator circuit matches the 13 pF specification to maintain frequency accuracy. Confirm RoHS compliance status if restricted substances are a constraint for the final product assembly.

Crystals Selection Notes

Select this component when a precise 12.8 MHz reference is required for digital systems. The 13 pF load capacitance must align with the host circuit's design parameters. Consider the ±30 ppm tolerance for system-level timing budgets. The 4-SMD package size requires adequate PCB real estate and solder paste deposition areas compatible with the 5x3.2 mm dimensions.

Crystals Part Context

This part belongs to the CTS 405 series of surface-mount crystals. The series offers various frequencies and packages optimized for high-volume electronics manufacturing. The 405I designation typically indicates industrial temperature rating within the manufacturer's lineup, distinguishing it from commercial grade options.

Crystals Replacement Considerations

Direct substitutes include other 12.8 MHz SMD crystals with matching 13 pF load capacitance and similar ESR values. Verify pin compatibility and thermal ratings before substitution.
