Crystals Procurement Notes

Verify the exact frequency tolerance and temperature range specifications against the official Suntsu Electronics datasheet before procurement. Ensure compatibility with the target circuit's load capacitance requirements. Confirm that the 4-SMD no-lead package aligns with your PCB footprint and assembly capabilities. Check for any specific ordering suffixes that may indicate variations in packaging or testing standards.

Crystals Selection Notes

Select this component when a 37.4 MHz reference is required with tight frequency stability. Consider the 18 pF load capacitance for oscillator circuit design. Evaluate the 40 Ohm ESR against the amplifier's drive level limitations. Compare package dimensions against available board space. Verify temperature range suitability for the intended operating environment.

Crystals Part Context

The SXT32418EE48-37.400M belongs to the SXT324 series of tuning fork crystals from Suntsu Electronics. This series is characterized by its small form factor and high-frequency capabilities. Similar parts in the series include variants with different frequencies such as 32.000 MHz, 36.000 MHz, and 48.000 MHz, all sharing similar electrical characteristics and package types.

Crystals Replacement Considerations

Direct substitutes within the same series include SXT32418EE48-36.000M and SXT32418EE48-48.000M, though frequency differences must be accounted for.
