Crystals Procurement Notes

Verify the specific suffix requirements against the target application's thermal and mechanical constraints. Confirm that the 4-SOJ package dimensions align with the printed circuit board land pattern. Ensure the operating temperature range meets the environmental specifications of the final product deployment. Cross-reference the manufacturer datasheet for any recent revisions to the mechanical drawing or electrical parameters before finalizing the bill of materials.

Crystals Selection Notes

Select this component when a standard 10 MHz reference is required in a surface-mount form factor. The 20 pF load capacitance must match the oscillator circuit design to ensure accurate frequency generation. Consider the ±50 ppm tolerance if tighter frequency accuracy is not critical for the application. The 60 Ω series resistance indicates moderate drive level sensitivity; verify that the host oscillator circuit does not exceed the specified power dissipation limits to prevent frequency drift or damage.
