Crystals Procurement Notes

Verify the specific manufacturer datasheet to confirm electrical parameters and mechanical dimensions prior to integration. Ensure that the selected variant matches the required load capacitance and ESR specifications for the target oscillator circuit. Cross-reference the KX-7T package style with PCB footprint libraries to guarantee accurate physical placement during manufacturing.

Crystals Selection Notes

Select this component when a 16 MHz reference signal is required within a limited board area. The 12 pF load capacitance must align with the host oscillator circuit design to maintain accuracy within the ±10 ppm tolerance. Consider the 60 Ohm ESR value to ensure proper drive level management and long-term stability in the final application environment.
