Crystals Procurement Notes

Verify the specific suffix 'CKT' against the manufacturer's current datasheet to confirm package type and termination style. Ensure the receiving facility handles components according to MSL ratings if applicable. Cross-reference the part number with official distributor catalogs to confirm active status and availability constraints before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 12 MHz reference is required in a minimal footprint SMD form factor. Consider the ±50 ppm stability requirement against system jitter specifications. Verify that the 18 pF load capacitance matches the oscillator circuit design. Confirm compatibility with reflow soldering profiles suitable for the 2-SMD package geometry.
