Crystals Procurement Notes

Verify the specific suffix 'ILR' against the manufacturer's current datasheet to confirm availability status and exact pin configuration. Ensure that the load capacitance requirements of the target circuit match the specified 12pF value to maintain frequency accuracy. Cross-reference the RoHS compliance status and moisture sensitivity level prior to final procurement decisions.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required with tight ±10 ppm stability across a wide -40°C to +85°C temperature span. The 60 Ohm ESR must be compatible with the driving circuit's impedance. Consider the 4-SMD footprint constraints and ensure the PCB layout accommodates the 2.00mm x 1.60mm package dimensions effectively.
