Crystals Procurement Notes

Verify the specific package variant and tolerance grade against project requirements before ordering. Confirm that the 18 pF load capacitance matches the host circuit design. Ensure compliance with RoHS directives if required by the manufacturing facility. Cross-reference the ESR value with oscillator driver strength specifications.

Crystals Selection Notes

Select this component when a precise 12 MHz reference is required for digital logic or communication interfaces. Consider the ±10 ppm tolerance for general-purpose timing where extreme stability is not critical. Evaluate the 50 Ohm ESR to ensure compatibility with the driving gate's output impedance. Verify space constraints against the HC49S footprint.
