Crystals Procurement Notes

Verify the specific manufacturer designation as listings may reference Abracon due to corporate acquisition history. Confirm that the trailing 'TR' indicates tape and reel packaging configuration suitable for high-volume surface mount production lines. Ensure compliance requirements match project specifications regarding RoHS directives and material declarations before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 16.384 MHz reference is required with moderate stability specifications. The 18 pF load capacitance must align with the oscillator circuit design parameters. Consider the physical dimensions and mounting style if space constraints exist within the target application board layout relative to other available crystal packages.
