Crystals Procurement Notes

Verify that the ordering suffix matches the required tolerance and packaging specifications. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations. Ensure the component is sourced from verified channels to guarantee authenticity and prevent counterfeit risks. Cross-reference the part number with the latest datasheet revisions to confirm electrical parameters align with system requirements before final procurement.

Crystals Selection Notes

Select this component when a 40 MHz timing source is required in a minimal footprint form factor. The 10 pF load capacitance must match the oscillator circuit design to ensure accurate frequency operation. Consider the 80 Ohm ESR value for compatibility with the driving gate impedance. Evaluate the ±30 ppm stability against system jitter requirements. Verify thermal performance within the specified operating temperature range for the intended application environment.

Crystals Part Context

This part belongs to the FTS 8Q series of miniature quartz crystals. The series offers various frequencies and package sizes optimized for modern electronics manufacturing. The 8Q designation indicates a specific leadless surface-mount technology suitable for automated pick-and-place assembly processes.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz crystals with identical 1.6x1.2 mm dimensions, 10 pF load capacitance, and ±30 ppm stability. Verify pinout compatibility and ESR values when cross-referencing alternative manufacturers.
