• Communication module frequency sources

Crystals Procurement Notes

Verify the exact suffix CAT against the official CTS datasheet to confirm the specific load capacitance and tolerance parameters. Ensure the ordering code matches the required 10 pF load capacitance specification. Cross-reference the package dimensions with your PCB footprint library before finalizing procurement orders to guarantee mechanical compatibility.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency source is required for space-constrained designs. The 4-SMD no-lead package offers advantages in high-volume automated assembly compared to through-hole alternatives. Consider the 100 Ohm ESR value when designing the oscillator circuit's feedback network to ensure stable startup conditions.

Crystals Part Context

This part belongs to the CTS 402 Series, a line of surface-mount crystals. The series typically includes variants with different load capacitances such as 9 pF or 12 pF, and varying frequency tolerances. The 402F270XXCAT specifically denotes the 10 pF load capacitance variant within this standardized product family.

Crystals Replacement Considerations

Direct substitutes include other 27 MHz SMD crystals with identical 10 pF load capacitance and similar physical dimensions. Verify that alternative manufacturers offer components with comparable ESR values and stability specifications to maintain circuit performance integrity.
