Crystals Procurement Notes

Verify the specific load capacitance requirement against the target circuit design, as this component utilizes an 18 pF specification which differs from other variants in the series. Confirm that the ±30 ppm stability meets the system's clock accuracy constraints. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to prevent mounting issues during assembly.

Crystals Selection Notes

Select this component when a fundamental mode crystal with 18 pF load capacitance is required for 27.12 MHz applications. Consider the 100 Ohm ESR value for oscillator circuit compatibility. Evaluate the -40°C to +85°C operating range against environmental conditions. Compare against legacy CTS models if existing designs require replacement, noting that some older series may not be recommended for new designs.
