Crystals Procurement Notes

Verify the specific ordering suffix against official CTS documentation to ensure correct electrical parameters. Confirm that the requested variant matches the required load capacitance and ESR specifications for your circuit design. Check current availability status as stock levels may vary by distributor.

Crystals Selection Notes

Select this component when a 19.6608 MHz reference is required in a larger 6.00mm x 3.50mm SMD footprint. Ensure the application environment stays within the specified -20°C to +70°C operating range. Verify that the 18pF load capacitance aligns with the oscillator circuit requirements.

Crystals Part Context

This part belongs to the CTS 406 Series of crystals, which are designed for general-purpose timing applications. The series provides various frequencies and package sizes, with the 406 series specifically offering larger footprints compared to the smaller 403 or 405 series options.
