• Consumer electronics control circuits

Crystals Procurement Notes

Verify the specific suffix AA07 against the manufacturer's official datasheet to confirm pinout and mechanical dimensions. Ensure the requested tolerance matches the ±50 ppm specification required by your circuit design. Cross-reference the package type to guarantee compatibility with your PCB footprint and reflow soldering profile.

Crystals Selection Notes

Select this component when a 37.4 MHz reference is required with moderate stability. The 15 pF load capacitance must match the external capacitors used in the oscillator circuit. Consider the 100 Ohm ESR limit to ensure proper oscillation startup conditions within the target application environment.

Crystals Part Context

This part belongs to the SXT21415 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and tolerances, utilizing standard 4-terminal packages. This specific model provides a mid-range frequency option for general-purpose timing applications where extreme precision is not critical.

Crystals Replacement Considerations

The SXT21415DB48-37.400M is a documented alternative offering tighter ±20ppm tolerance. Verify if the improved stability justifies any potential cost or availability differences. Ensure the replacement maintains the same 15pF load capacitance and 4-SMD package form factor.
