Procurement Notes
Verify the specific ordering suffix to confirm packaging configuration, as bulk tape specifications may vary. Ensure the selected variant matches the required load capacitance and frequency tolerance for the target circuit design. Confirm compliance with current environmental directives such as RoHS3 before finalizing procurement orders.
Selection Notes
Select this component when a 20 MHz reference signal is required for surface-mount designs. The 18 pF load capacitance must align with the oscillator circuit's input capacitance requirements. Consider the 40 Ohm ESR limit to ensure adequate drive level handling within the application circuit.
Part Context
This part belongs to the CFPX-104 series of SMD crystals from IQD Frequency Products. It represents a standard solution for general-purpose timing applications requiring high reliability and compact dimensions.
