Crystals Procurement Notes

Verify the specific suffix against official documentation to confirm functional equivalence, as ordering codes may indicate variations in packaging or specifications not evident from general descriptions. Confirm that the required load capacitance matches the circuit design before procurement. Ensure compliance with project-specific environmental regulations such as REACH status. Cross-reference the manufacturer's latest datasheet to validate current production status and availability constraints prior to finalizing supply chain agreements.

Crystals Selection Notes

Select this component when a stable 7.3728 MHz reference is required for digital systems utilizing standard microcontrollers or communication protocols. The 18 pF load capacitance must align with the oscillator circuit's input capacitance requirements. Consider the ±30 ppm stability specification for applications where moderate frequency drift is acceptable within the industrial temperature range. The HC-49/US-SM form factor offers a balance between performance and board space efficiency compared to through-hole alternatives.
