Crystals Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's latest datasheet before procurement. Confirm that the selected component matches the required load capacitance and frequency tolerance specifications for the target application. Ensure compliance with RoHS directives and check for any regional distribution restrictions or end-of-life notifications prior to finalizing supply chain agreements.

Crystals Selection Notes

Select this component when a 40 MHz timing source is required within a compact surface-mount footprint. Consider the ±30 ppm stability limit and the -20°C to +70°C operating range to ensure compatibility with environmental conditions. Evaluate the 12 pF load capacitance requirement against the oscillator circuit design to guarantee accurate frequency operation without additional tuning adjustments.
