Crystals Procurement Notes

Verify the specific load capacitance requirement of your circuit against the component's 10pF specification to ensure accurate frequency performance. Confirm that the PCB footprint matches the 2.00mm x 1.60mm package dimensions. Check for RoHS3 compliance if environmental regulations apply to your assembly process. Ensure the operating temperature range meets your system's thermal requirements.

Crystals Selection Notes

Select this component when a stable 27.12 MHz reference is required in a space-constrained surface mount design. Consider the 100 Ohm ESR value for oscillator circuit compatibility. The ±10ppm stability makes it suitable for applications demanding tighter tolerances than standard crystals. Evaluate the 4-SMD package for automated assembly feasibility.

Crystals Part Context

This part belongs to the 402 Series of MHz crystals from CTS-Frequency Controls. The series offers various frequencies and load capacitances in standardized SMD packages. The 402F27112IAR specifically addresses the need for 27.12 MHz timing in modern electronics, providing a balance between size, stability, and cost-effectiveness for mass production.

Crystals Replacement Considerations

Direct substitutes include 402F27112IDT and 402F27112IKR. Verify that alternative parts match the 10pF load capacitance and ±10ppm stability. Ensure the replacement maintains the same 4-SMD package dimensions and ESR characteristics for pin-to-pin compatibility.
