Crystals Procurement Notes

Verify the specific suffix 'IAT' against official datasheets to confirm package type and tape/reel specifications. Ensure the target circuit design supports the 10pF load capacitance requirement. Confirm that the ±15ppm initial frequency tolerance meets system timing accuracy requirements before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 27.12 MHz reference is required in a small surface-mount form factor. Compare ESR values against oscillator circuit drive levels to ensure stability. Verify that the 120 Ohm ESR is compatible with the host MCU or oscillator IC input impedance specifications for reliable startup.

Crystals Part Context

This part belongs to the CTS 416 Series, a line of high-stability AT-cut crystals intended for general-purpose electronic applications. The series offers various load capacitances and tolerances to suit different oscillator designs while maintaining consistent physical dimensions for board layout standardization across product families.

Crystals Replacement Considerations

Equivalent substitutes include 416F271X3CAR and 416F271X3IKR from CTS-Frequency Controls. These parts share identical electrical parameters but may differ in packaging suffixes. Verify package compatibility and reflow profile alignment before substitution.
