Crystals Procurement Notes

Verify the specific datasheet version corresponding to the SXT11412DA48-40.000M part number before procurement. Confirm that the required frequency tolerance of ±20 ppm meets system requirements. Ensure compatibility with the 12 pF load capacitance in the target circuit design. Check for any RoHS or REACH compliance documentation provided by Suntsu Electronics, Inc. for regulatory adherence.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required in a compact surface-mount form factor. Consider the 100 Ohm ESR value for oscillator circuit stability. Evaluate the ±20 ppm tolerance against the system's jitter and phase noise specifications. Compare the 4-SMD package dimensions against available PCB real estate constraints.

Crystals Part Context

This part belongs to the SXT114 series of surface-mount crystals from Suntsu Electronics, Inc. The series offers various frequency options within the same physical footprint. The DA48 suffix indicates specific dimensional and mounting characteristics common to this product line. It serves as a passive resonator element requiring external amplifier circuitry.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 12 pF load capacitance, and 4-SMD no-lead package. Verify equivalent ESR values to ensure oscillator startup reliability. Cross-reference pinout definitions if alternative manufacturers offer different terminal arrangements.
