Crystals Procurement Notes

Verify the specific suffix CAT against the official CTS datasheet to confirm the exact load capacitance and packaging configuration. Ensure the operating temperature range of -20°C to +70°C aligns with the target application environment. Cross-reference the ESR value of 100 Ohms with circuit requirements to guarantee proper oscillation startup conditions.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental frequency is required with moderate stability. The 10pF load capacitance must match the oscillator circuit design. Consider the 4-SMD footprint for PCB layout constraints. Verify that the commercial temperature range meets operational needs before finalizing the part number selection.

Crystals Part Context

This part belongs to the 402 series of crystals from CTS-Frequency Controls. The series offers various frequencies and packages. The 402F271XXCAT specifically targets applications requiring a 27.12 MHz reference. It is distinct from other suffixes like CJR or CKR which may differ in load capacitance or packaging quantity.

Crystals Replacement Considerations
