Crystals Procurement Notes

Verify the specific suffix 'E' against the official CTS datasheet to confirm load capacitance and tolerance specifications. Ensure the design-in process accounts for the 60 Ohm ESR and 20pF load requirements. Confirm that the 4-SMD footprint matches the PCB layout guidelines provided in the manufacturer's documentation before finalizing procurement.

Crystals Selection Notes

Select this component when a 16.384 MHz fundamental frequency is required with ±30ppm initial tolerance. The 20pF load capacitance must match the oscillator circuit design. Consider the -20°C to 70°C operating range for industrial or commercial environments. The 4-SMD package offers space efficiency compared to through-hole alternatives.

Crystals Part Context

This part belongs to the CTS 405 Series of surface-mount crystals. The series provides various frequencies and packages optimized for high-volume manufacturing.
