Crystals Procurement Notes

Verify the suffix 'S' against official documentation to confirm specific performance variations compared to standard variants like 'E'. Ensure circuit design accounts for the 40 Ohm ESR and 20 pF load capacitance requirements. Confirm RoHS3 compliance status through current manufacturer declarations before final procurement.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency is required in a compact 6x3.5 mm SMD package. The ±30 ppm tolerance suits general-purpose timing applications. Verify that the -20°C to +70°C operating range meets environmental constraints. Compare ESR specifications against oscillator drive level limits to ensure stable operation.

Crystals Part Context

This part belongs to the CTS 406 Series of surface-mount crystals. It shares dimensional standards with other members but differs in electrical parameters such as ESR and frequency based on the specific model suffix. The series provides standardized footprints for easy PCB layout integration across various frequency options.

Crystals Replacement Considerations

Direct substitutes include 406C35E20M00000 and 406I35E20M00000 from CTS-Frequency Controls. These alternatives share identical dimensions and nominal frequencies but may exhibit different ESR values or temperature stability characteristics. Validate electrical compatibility before substitution.
