Crystals Procurement Notes

Verify the specific ordering suffix to ensure the correct tolerance and packaging configuration matches the design requirements. Confirm that the manufacturer designation aligns with Shenzhen SCTF Electronics specifications. Cross-reference the ESR and load capacitance values against the target circuit schematic to guarantee compatibility. Ensure the package dimensions conform to the PCB footprint layout constraints before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 40 MHz frequency reference with ±10 ppm initial accuracy is required. The 30 Ohm ESR specification suits standard oscillator circuits without excessive loading. The 8 pF load capacitance requirement must be matched with the oscillator circuit's stray capacitance. Consider the SMD3225-4P package size for assembly compatibility with existing surface mount manufacturing processes.
