Crystals Procurement Notes

Verify that the specific suffix 'EII' corresponds to the 16 pF load capacitance variant, as other suffixes in the 8Q series may indicate different electrical parameters such as 8 pF or 12 pF. Confirm RoHS compliance status and ensure the ordering quantity aligns with the manufacturer's standard packaging requirements. Cross-reference the datasheet to validate the ESR value of 80 Ohms for the intended circuit design.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental mode crystal with ±10 ppm stability is required. Ensure the application circuit provides a 16 pF load capacitance to maintain frequency accuracy. Consider the -20°C to +70°C operating range against environmental conditions. Compare against other 8Q series variants if different load capacitances or tighter tolerances are needed for the specific system architecture.
