Crystals Procurement Notes

Verify that the specific part number matches the required load capacitance and frequency tolerance for your circuit design. Confirm that the operating temperature range aligns with your environmental specifications. Ensure compatibility with surface-mount reflow soldering profiles. Check for any recent updates to the datasheet regarding pin configurations or mechanical dimensions before finalizing procurement orders.

Crystals Selection Notes

Select this component when a fundamental mode crystal is preferred over overtone modes for lower phase noise characteristics. Consider the 10 pF load capacitance requirement to ensure proper oscillator circuit tuning. Evaluate the 60 Ohm ESR against your oscillator driver strength capabilities. The industrial temperature range suits most general-purpose electronic applications without requiring extended grade components.
