Crystals Procurement Notes

Verify the specific suffix codes against official CTS documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the selected variant matches the required load capacitance and ESR specifications for the target circuit design. Cross-reference the manufacturer's latest datasheet to validate compliance with current environmental regulations and RoHS standards before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 27 MHz fundamental mode crystal is required for surface-mount assembly. Evaluate the 60 Ohm ESR against the oscillator circuit's drive level requirements to prevent over-driving the crystal. Confirm that the 20 pF load capacitance aligns with the host system's external capacitor values. Verify that the -20°C to +70°C temperature range meets the operational environment constraints of the end product.
