Crystals Procurement Notes

Verify the exact datasheet from Suntsu Electronics to confirm current specifications, as distributor listings may vary. Ensure the ordering suffix matches the required stability and packaging options. Cross-reference part numbers carefully to avoid confusion with similar models like the EA variant which may have different stability ratings. Request official documentation before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required for SMD applications. The 8 pF load capacitance must match the circuit design requirements. Consider the ±15 ppm tolerance for precision needs. Evaluate the -20°C to +70°C operating range against environmental conditions. Compare ESR values with other available options to ensure compatibility with the oscillator circuit.
