Crystals Procurement Notes

Verify the specific suffix 'IKT' corresponds to the required tape and reel packaging configuration, as alternative suffixes may indicate different handling or storage requirements. Confirm that the commercial temperature rating of -20°C to +70°C aligns with the operational environment constraints of the target application design. Ensure compatibility with standard reflow soldering profiles for 4-SMD components.

Crystals Selection Notes

Select this component when a 40.61 MHz reference is required in a space-constrained surface mount layout. The 8pF load capacitance must match the oscillator circuit design specifications to ensure accurate frequency performance. Consider the ±30ppm initial tolerance and ±50ppm total stability limits against the system's jitter and phase noise requirements. Evaluate the 60 Ohm ESR value for compatibility with the driving gate circuit impedance.
