Crystals Procurement Notes

Verify the specific suffix 'D' against the manufacturer's current datasheet to confirm the exact load capacitance and ESR parameters, as variations exist within the 406 series. Ensure the selected variant matches the required 18 pF load capacitance and 40 Ohm ESR for the target circuit design. Confirm package compatibility with the PCB footprint before ordering.

Crystals Selection Notes

Select this component when a surface-mount solution is required for 40 MHz applications. The 406 series offers a balance of performance and size. Consider the 40 Ohm ESR value for oscillator circuit design to ensure proper startup conditions. Verify that the operating temperature range of -20°C to +70°C meets the environmental requirements of the final application.

Crystals Part Context

This part belongs to the CTS 406 Series of surface-mount crystals. The series is designed for general electronic applications requiring reliable frequency control.
