Crystals Procurement Notes

Verify the specific suffix 'B' against official CTS documentation to confirm the 13pF load capacitance specification, as variations exist within the 406 series. Ensure the ordering part number matches the exact frequency and tolerance requirements for your design. Cross-reference the datasheet for any recent updates regarding lead-free compliance or packaging changes before finalizing procurement.

Crystals Selection Notes

Select this component when a 12.288 MHz fundamental mode crystal is required for space-constrained designs. The 4-SMD no-lead package offers a compact footprint suitable for high-density PCB layouts. Consider the ±30 ppm tolerance and 60 Ohm ESR limits to ensure compatibility with the oscillator circuit's drive level and loading capacitance constraints.

Crystals Part Context

This component belongs to the 406 series of SMD crystals from CTS-Frequency Controls. The series provides various frequencies and packages, with the 406C35 variant specifically denoting the 6.0x3.5mm form factor. This model represents a standard industrial-grade option for general-purpose timing applications requiring reliable frequency stability.

Crystals Replacement Considerations
