Crystals Procurement Notes

Verify exact frequency tolerance and stability specifications against the manufacturer's current datasheet prior to procurement. Confirm that the 4-SMD no-lead package dimensions align with the target PCB layout requirements. Ensure thermal management strategies account for the specific operating temperature range defined in the official documentation to maintain long-term reliability.

Crystals Selection Notes

Select this component when a precise 12.288 MHz reference is required for digital logic circuits. The 20 pF load capacitance must match the external circuit design to ensure accurate frequency output. Consider the 100 Ohm ESR limits when evaluating drive level sensitivity. This part is suitable for applications requiring standard commercial temperature performance without specialized industrial or automotive certifications.

Crystals Part Context
