Crystals Procurement Notes

Verify the specific suffix 'M' against the manufacturer's official datasheet to confirm the exact frequency tolerance and temperature range specifications. Ensure the ordering part number matches the required load capacitance and ESR values for your circuit design. Confirm RoHS compliance status if restricted substances are a constraint for your project.

Crystals Selection Notes

Select this component when space constraints require a 2520 footprint but electromagnetic compatibility is critical. The four-terminal ground connection reduces radiated emissions, making it suitable for sensitive RF environments. Consider the ±30ppm tolerance limit to ensure it meets the frequency accuracy requirements of the host microcontroller or transceiver.

Crystals Part Context

This model belongs to the SXT224 series of industrial-grade crystals from Suntsu Electronics. The series offers various frequency options within the 12MHz to 66MHz range. The 4-pad configuration distinguishes it from standard 2-pin SMD crystals by providing better grounding and noise immunity for high-frequency digital and RF circuits.

Crystals Replacement Considerations

Direct substitutes must match the 2.5x2.0mm 4-SMD package, 50MHz frequency, 13pF load capacitance, and ≤50Ω ESR. Verify that alternative components support the same industrial temperature range and offer comparable EMI shielding characteristics due to the pin configuration.

Crystals FAQ

Does the SXT22413BB16-50.000M require external capacitors for load matching?

No, the internal load capacitance is specified as 13pF. External capacitors may be needed for circuit tuning, but no large series capacitors are required for basic operation.

What is the maximum drive level for this crystal?

The maximum drive level is 100μW. Standard designs typically operate between 10μW and 50μW to ensure longevity and stability.
