Crystals Procurement Notes

Verify the specific suffix ILR against official CTS documentation to confirm tape and reel packaging requirements. Ensure the requested quantity aligns with standard manufacturer packaging specifications. Cross-reference the full part number to validate availability status and current production lifecycle stage before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental frequency with ±10ppm stability is required. The 12pF load capacitance must match the oscillator circuit design. Consider the 100 Ohm ESR for impedance matching. The 4-SMD footprint requires compatible PCB land patterns. Verify thermal performance meets the -40°C to +85°C operational range for the target environment.

Crystals Part Context

This component belongs to the CTS 402 series of sealed ceramic surface-mount crystals. The series offers various frequencies between 16 MHz and 60 MHz. The 402F27112ILR specifically provides tighter frequency tolerances compared to standard ±30ppm variants. It is designed for automated assembly processes using standard SMD reflow techniques.

Crystals Replacement Considerations

Direct substitutes include 402F27112IAR and 402F27112IJR from CTS-Frequency Controls. These alternatives share identical electrical parameters and physical dimensions. Verify package compatibility and ensure the substitute maintains the same ±10ppm stability rating.
