Procurement Notes

Verify the specific packaging configuration (Cut Tape, MouseReel, or Reel) required for your production line before ordering. Confirm that the 48 MHz frequency and 18 pF load capacitance match your circuit design requirements. Ensure compatibility with the specified operating temperature range and drive level to maintain performance integrity.

Selection Notes

Select this component when a 48 MHz reference signal is required in a small form factor. Consider the ±20 ppm tolerance and ±30 ppm stability for applications demanding precise timing. Evaluate the 3.4 mm x 2.7 mm footprint against available board space and ensure the SMD mounting style aligns with your assembly capabilities.

Part Context

This part belongs to the CFPX-180 series of crystals from IQD Frequency Products. It is a fundamental mode quartz crystal resonator intended for general-purpose timing applications. The series offers various frequencies and packages, with this specific model providing a standard 48 MHz output in a widely used surface-mount enclosure.

Replacement Considerations

Direct substitutes must match the 48 MHz frequency, 18 pF load capacitance, and 3.4 mm x 2.7 mm package dimensions. Verify equivalent tolerance and stability specifications to ensure circuit compatibility.
