Procurement Notes

Verify the specific ordering suffix and reel quantity requirements directly with the manufacturer or authorized distributors before placing orders. Confirm that the current revision matches the design specifications, as part numbers may undergo revisions without functional changes. Ensure compliance with RoHS directives and check for any specific handling instructions related to the surface mount package type during assembly.

Selection Notes

Select this component when a 12 MHz fundamental frequency is required with tight stability constraints. The 12 pF load capacitance must match the oscillator circuit design to ensure accurate frequency generation. Consider the 120 Ohm ESR value for compatibility with the driving circuit's power requirements. The extended temperature range makes it suitable for applications exceeding standard commercial limits.
