Crystals Procurement Notes

Verify the specific ordering suffix against the official datasheet to ensure correct packaging and tape/reel specifications. Confirm that the selected variant matches the required load capacitance and frequency tolerance for your design. Check for any recent updates to the RoHS compliance status or material declarations. Ensure the supplier provides traceability documentation consistent with Class III life supporting device requirements. Validate that the component meets all environmental operating conditions defined in the manufacturer's technical data.

Crystals Selection Notes

Select this component when a precise 12 MHz reference is required for surface mount designs. The ±50ppm tolerance suits applications where moderate frequency stability is acceptable. Consider the 30pF load capacitance compatibility with the oscillator circuit's input characteristics. Evaluate the 100 Ohm ESR against the driving level constraints of the host system. Ensure the 4-SMD footprint aligns with the PCB layout guidelines provided in the official documentation.
