Crystals Procurement Notes

Verify the specific suffix IKT against official CTS documentation to confirm the exact load capacitance and temperature range, as variations exist within the 402 series. Confirm availability status directly with authorized distributors, as part status may change. Ensure compatibility with existing PCB footprint dimensions of 2.00mm x 1.60mm during procurement planning.

Crystals Selection Notes

Select this component when a 27.12 MHz reference with ±20 ppm stability is required for surface-mount assembly. Consider the 8 pF load capacitance requirement for circuit design matching. Evaluate the -40°C to +85°C range against application thermal profiles. Compare ESR specifications with oscillator circuit requirements to ensure proper startup and stability.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals, designed for high-reliability applications. The series offers various frequencies and packages, with the 402F27122IKT specifically targeting 27.12 MHz needs. It represents a standard solution for timing applications where space constraints and environmental durability are critical factors.

Crystals Replacement Considerations

Direct substitutes include other 27.12 MHz SMD crystals from CTS with identical electrical parameters and package dimensions. Verify that alternative parts match the 8 pF load capacitance and 100 Ohm ESR. Cross-reference with other manufacturers offering 2x1.6mm 4-SMD crystals if supply chain diversification is necessary.
