Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm exact electrical tolerances and packaging configurations. Ensure the selected variant matches the required load capacitance and ESR values for the target circuit design. Cross-reference the RoHS status and moisture sensitivity level during procurement planning to guarantee compliance with assembly standards.

Crystals Selection Notes

Select this component when a 38.4 MHz fundamental frequency with ±15 ppm tolerance is required in a small form factor. The 18 pF load capacitance must align with the oscillator circuit's input requirements. Consider the -20°C to +70°C operating range for environmental suitability. The low profile SMD package facilitates automated placement in high-density PCB layouts.

Crystals Part Context
