Oscillators Procurement Notes

Verify the exact load capacitance requirements against your circuit design before procurement. Ensure the operating temperature range specified in the manufacturer's datasheet aligns with your application environment. Confirm that the HC-49/U package dimensions fit within your board layout constraints. Cross-reference the part number suffix to ensure no variations in frequency or tolerance exist.

Oscillators Selection Notes

Select this component when a standard 19.2 MHz reference is required for through-hole assembly. Consider the HC-49/U package size relative to available board space. Evaluate the cost-effectiveness compared to surface-mount alternatives if space is not a primary constraint. Verify compatibility with the driving circuit's load capacitance specifications to ensure accurate frequency output.
