Crystals Procurement Notes

Verify the specific suffix 'D' against official datasheets to confirm the 20pF load capacitance specification, as variations exist within the 405 series. Ensure the application circuit matches the 20pF requirement rather than standard 18pF or 13pF variants. Confirm RoHS3 compliance status directly with the manufacturer documentation prior to final design approval.

Crystals Selection Notes

Select this component when a 14.31818 MHz reference is required for industrial environments. The 20pF load capacitance distinguishes it from common 18pF variants. Verify that the target PCB layout accommodates the 5.00mm x 3.20mm dimensions and that the driving circuit can support the specified ESR value for stable oscillation.

Crystals Part Context

This part belongs to the CTS 405 Series of surface-mount crystals. The series offers various frequencies and load capacitances in standardized SMD packages. The 405I designation indicates industrial temperature rating capabilities, differentiating it from commercial grade options within the same physical form factor family.
