Crystals Procurement Notes

Verify the specific suffix 'K' against the official CTS datasheet to confirm exact load capacitance and tolerance specifications, as suffix variations define critical electrical parameters. Ensure the requested quantity aligns with manufacturer standard packaging requirements. Confirm RoHS compliance status and moisture sensitivity level prior to integration into the supply chain.

Crystals Selection Notes

Select this component when a 14.31818 MHz reference is required with ±30ppm initial tolerance. The 18pF load capacitance must match the oscillator circuit design. The 50 Ohm ESR limits suitability for high-drive applications. Consider the -20°C to +70°C operating range for environmental constraints.
