Crystals Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target circuit design before procurement. Confirm that the HC-49/US package dimensions align with the PCB footprint constraints. Ensure the drive level specification matches the oscillator circuit capabilities to prevent frequency instability or crystal damage during operation.

Crystals Selection Notes

Select this component when a standard 19.6608 MHz reference is required for digital logic timing. The HC-49/US form factor provides robust mechanical stability for general-purpose applications. Consider the ±30 ppm tolerance for systems requiring precise baud rate matching or clock synchronization where higher precision variants are not necessary.
