Crystals Procurement Notes

Verify the specific suffix 'D' against official CTS documentation to confirm exact frequency tolerance and stability specifications. Ensure the selected variant matches the required load capacitance and ESR values for the target circuit design. Confirm compliance with project-specific environmental regulations such as RoHS3 before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 22.1184 MHz reference is needed in a small 3.2x2.5mm footprint. Consider the ±30 ppm tolerance and 60 Ohm ESR limits relative to the oscillator circuit's requirements. Verify that the -40°C to +85°C temperature range meets the operational environment constraints of the end application.
