Crystals Procurement Notes

Verify the specific load capacitance and ESR requirements against your circuit design before procurement. Ensure the 4-SMD package dimensions align with your PCB footprint. Confirm that the ±20ppm stability meets your system's timing accuracy needs. Request the official datasheet from Suntsu Electronics to validate electrical parameters for your specific application environment.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental frequency is required with moderate stability. The 8pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR limit for power consumption constraints. The surface-mount form factor is suitable for high-volume manufacturing where space efficiency is critical.

Crystals Part Context

This part belongs to the SAX2148 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies with consistent package dimensions. The DA4B suffix indicates specific electrical characteristics including load capacitance and ESR limits. This model provides a standardized solution for timing applications requiring reliable frequency control.

Crystals Replacement Considerations

Direct substitutes include other 27.12 MHz crystals with identical 8pF load capacitance and ≤60 Ohm ESR. Verify package compatibility for 4-SMD No Lead configurations. Cross-reference with Suntsu part numbers like SAX2148DA4B-20.000M for similar mechanical footprints if frequency differences are acceptable.
