Crystals Procurement Notes

Verify the specific suffix 'IKT' against the manufacturer's official datasheet to confirm pinout and electrical characteristics. Ensure the selected variant matches the required load capacitance and ESR values for the target circuit design. Check current availability status as components may be subject to supply constraints or obsolescence notices.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency with tight ±10ppm stability is required. The 8pF load capacitance must align with the host oscillator circuit's external capacitor requirements. Consider the 4-SMD footprint and 0.55mm height for PCB layout compatibility and reflow soldering profiles.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series offers various frequencies and packages optimized for space-constrained electronic designs. The 402F40012IKT specifically targets applications needing reliable timing at 40 MHz with standard commercial temperature ranges.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz SMD crystals with identical 8pF load capacitance, ≤60 Ohm ESR, and ±10ppm tolerance. Verify mechanical footprint compatibility (2.00mm x 1.60mm) and thermal characteristics before substitution.
