Crystals Procurement Notes

Verify that the ordering suffix matches the required frequency tolerance and temperature range specifications. Confirm the package type corresponds to the 4-SMD no-lead variant. Ensure the load capacitance aligns with the target oscillator circuit requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 3225 footprint is required with superior EMI performance compared to two-terminal alternatives. Consider the ±10 ppm frequency stability option for industrial applications requiring precise clock synchronization. Evaluate the wide operating temperature range availability if deployment involves extreme environmental conditions.

Crystals Part Context

This part belongs to the SXT324 series, a line of industrial-grade ceramic surface-mount crystals. The series supports fundamental frequencies from 8 MHz to 70 MHz and overtone modes up to 170 MHz. The SXT3248CB48 designation indicates a specific pinout and package style optimized for automated assembly processes.

Crystals Replacement Considerations

Direct substitutes include other SXT324 series variants such as SXT3248CB48-25.000M or SXT3248CB48-20.000M, provided the frequency difference is acceptable for the application.
