Crystals Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific suffix matches the required load capacitance and ESR values for your circuit design. Check for recent product change notifications regarding material composition or packaging updates to ensure compatibility with current assembly processes.

Crystals Selection Notes

Select this component when a standard 3.6864 MHz frequency is required for basic timing functions. The ±50 ppm tolerance is suitable for non-critical communication protocols. Ensure the target application environment remains within the specified -20°C to +70°C operational range to maintain frequency accuracy. Verify that the 150 Ohm ESR aligns with the oscillator circuit's drive level requirements.
