Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure exact electrical characteristics match the design requirements. Confirm that the package type corresponds to the intended footprint on the printed circuit board. Check for any recent revisions in the product documentation that may affect compatibility or performance specifications before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required with moderate stability needs. The ±10ppm tolerance suits general-purpose timing applications where high precision is not critical. Ensure the 8pF load capacitance aligns with the oscillator circuit design. Consider the 100 Ohm ESR value for impedance matching purposes within the target electronic system architecture.

Crystals Part Context
