Procurement Notes

Verify the specific packaging variant when ordering, as suffixes may indicate bulk or tape-and-reel configurations. Confirm that the 26 MHz frequency and 10 pF load capacitance align with the target circuit design requirements. Ensure compatibility with the 5 mm x 3.2 mm footprint during PCB layout. Cross-reference the datasheet for exact mechanical dimensions to guarantee proper placement and soldering processes.

Selection Notes

Select this component for applications requiring a 26 MHz reference with high stability. The 40 Ohm ESR value must be compatible with the oscillator circuit's drive level specifications. Consider the physical dimensions of the CFPX-104 package for space-constrained designs. Verify that the operating temperature range meets the environmental conditions of the intended application.
