Crystals Procurement Notes

Verify the specific suffix IKR against official CTS documentation to confirm packaging and handling characteristics. Ensure the design-in process accounts for the 8 pF load capacitance requirement to maintain frequency accuracy within the specified ±10 ppm tolerance. Confirm that the selected PCB layout supports the 4-SMD footprint dimensions and thermal requirements for the -40°C to +85°C operating range.

Crystals Selection Notes

Select this component when a 27.12 MHz reference is required in a space-constrained surface-mount design. The 8 pF load capacitance must match the circuit's stray capacitance to achieve the stated ±10 ppm tolerance. Consider the 4-SMD package size for assembly compatibility and verify that the base mode operation aligns with the target oscillator circuit topology.
