Crystals Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm exact electrical tolerances and packaging variations. Ensure compatibility with surface-mount reflow profiles. Confirm availability status as supply constraints may affect lead times. Cross-reference pinout and footprint dimensions with PCB design requirements prior to integration.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required in a small surface-mount footprint. The 10pF load capacitance must match the oscillator circuit design. Consider the ±10ppm tolerance for applications requiring tight frequency accuracy. Evaluate the 60 Ohm ESR against driver strength limitations in the target application.
