Crystals Procurement Notes

Verify the specific suffix 'IDR' against official CTS documentation to confirm tape-and-reel packaging configuration. Ensure the selected variant matches the required load capacitance and ESR specifications for the target circuit design. Cross-reference the part number with current manufacturer availability lists, as supply status may vary by region and distributor channel.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency with ±10 ppm tolerance is required in a 1612 metric case size. Confirm that the system load capacitance aligns with the specified 18 pF value to maintain accurate frequency output. Evaluate thermal requirements against the -40°C to +85°C operational range before integration into the final assembly.

Crystals Part Context
