Crystals Procurement Notes

Verify the exact suffix 'D' against official CTS documentation to confirm the specific variant characteristics, as ordering codes may denote packaging or minor specification differences. Ensure the design accounts for the 40 Ohm ESR and 20pF load capacitance requirements. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 16.67 MHz fundamental frequency is required with moderate stability needs. The 40 Ohm ESR and 20pF load capacitance must match the oscillator circuit design. Consider the -20°C to +70°C operating range for environmental suitability. The 4-SMD package offers space efficiency compared to through-hole alternatives.

Crystals Part Context

This crystal belongs to the 407 series from CTS-Frequency Controls, which focuses on surface-mount resonators.
