Crystals Procurement Notes

Verify the specific suffix 'E' against the manufacturer datasheet to confirm the exact temperature range and tolerance specifications, as suffix variations may alter electrical parameters. Ensure the ordering documentation matches the required 20pF load capacitance and 40 Ohm ESR values for circuit compatibility. Cross-reference the package dimensions with the PCB footprint library to prevent mounting errors during assembly.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency is required for surface-mount designs. The 20pF load capacitance must match the oscillator circuit design requirements. Consider the -20°C to +70°C operating range for standard commercial applications. Verify that the 40 Ohm ESR aligns with the driving circuit constraints to ensure reliable oscillation startup.

Crystals Part Context

This part belongs to the CTS 406 series of surface-mount crystals. The series offers various frequencies and package sizes optimized for high-volume manufacturing.
