Crystals Procurement Notes

Verify exact package dimensions against PCB footprint requirements before ordering. Confirm that the specified operating temperature range aligns with the target application environment. Ensure compatibility with reflow soldering profiles suitable for the HC-49/US-SM form factor. Check current availability status as this item may not be normally stocked. Validate RoHS compliance documentation if required by specific project regulations.

Crystals Selection Notes

Select this component when a 19.2 MHz fundamental frequency is required for surface-mount applications. Consider the 20pF load capacitance requirement for oscillator circuit design. Evaluate the 40 Ohms ESR against the driving circuit capabilities. Compare the HC-49/US-SM size constraints with available board space. Assess the -20°C to 70°C temperature range against operational conditions.
