Crystals Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure correct frequency and tolerance specifications. Confirm that the selected variant matches the required load capacitance and ESR values for the target circuit design. Check current availability status as lead times may vary based on production schedules.

Crystals Selection Notes

Select this component when a 44.736 MHz fundamental frequency is required in a small surface-mount footprint. Ensure the application environment stays within the specified -20°C to +70°C operating range. Verify that the circuit's load capacitance aligns with the 18pF specification to maintain accurate frequency performance.

Crystals Part Context

This component belongs to the 407 series of crystals from CTS-Frequency Controls. The series offers various frequencies in standard SMD packages.
