Crystals Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required load capacitance and tolerance levels. Confirm that the 4-SMD no-lead package dimensions align with PCB footprint constraints. Check RoHS compliance status if restricted substances are prohibited in your manufacturing process. Ensure the selected variant matches the target frequency of 38.4 MHz exactly. Review datasheet specifications for operating temperature range limitations before finalizing procurement.

Crystals Selection Notes

Select this component when precise timing accuracy within ±10 ppm is critical for system performance. The 60 Ohm ESR value must match the oscillator circuit design requirements to ensure reliable startup. Consider the 8 pF load capacitance requirement when designing the PCB layout and trace lengths. The small 2.50mm x 2.00mm package size makes it suitable for space-constrained designs. Evaluate thermal stability needs against the specified operating temperature range.
