• Frequency stabilization in communication modules

Crystals Procurement Notes

Verify the exact physical dimensions and terminal plating specifications against the official Suntsu Electronics datasheet before finalizing the PCB footprint. Ensure that the soldering profile complies with the thermal requirements specified for 4-SMD no-lead packages to maintain reliability and prevent mechanical stress during reflow processes.

Crystals Selection Notes

Select this component when a 27.12 MHz timing source with ±20 ppm stability is required. The 12 pF load capacitance must match the circuit design requirements. Consider the 100 Ohm ESR value for oscillator circuit compatibility. The no-lead package offers advantages for high-volume automated manufacturing compared to traditional leaded variants.

Crystals Part Context

This part belongs to the SXT214 series of surface-mount crystals from Suntsu Electronics. The series provides various frequency options within a standardized small form factor. The specific model indicates a 27.12 MHz output, distinguishing it from other frequencies available in the same package family such as 25.000 MHz variants.

Crystals Replacement Considerations

Direct substitutes include other 27.12 MHz crystals with identical 12 pF load capacitance and compatible ESR values. Verify that alternative manufacturers offer the same 4-SMD no-lead package dimensions to ensure mechanical interchangeability without PCB redesign.
