Crystals Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the HC-49/US package dimensions align with the printed circuit board layout constraints. Ensure the operating temperature range meets the environmental specifications of the final application. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Crystals Selection Notes

Select this component when a standard 14.31818 MHz reference is required for digital systems. The 18 pF load capacitance matches common oscillator configurations. Consider the 40 Ohm ESR for impedance matching within the driving circuit. The through-hole mounting style is suitable for prototyping or high-reliability assemblies where surface mount options are not preferred.

Crystals Part Context
