Crystals Procurement Notes

Verify current availability status through authorized distributors, as supply chain conditions may vary. Confirm that the specific ordering suffix matches the required tolerance and packaging configuration. Ensure compatibility with existing PCB footprint dimensions and reflow soldering profiles. Cross-reference the manufacturer datasheet for any recent updates regarding environmental compliance or pinout definitions before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 19.2 MHz fundamental frequency is required with tight initial tolerance. The 12pF load capacitance must match the oscillator circuit requirements. Consider the 120 Ohm ESR value for drive level sensitivity. The 4-SMD package size dictates the available board space. Verify thermal performance against the specified -40°C to +85°C operational limits for the target environment.
