The component features a frequency tolerance of ±10 ppm and is housed in a 4-SOJ package with a 5.50 mm pitch, measuring 8.0 mm x 3.8 mm.

Crystals Feature Summary

• Surface-mount design for automated assembly
• Fundamental mode operation at 18.432 MHz
• Standard 18 pF load capacitance compatibility

Crystals Applications

• Microcontroller clock sources
• Digital signal processing circuits
• Communication interface timing

Crystals Procurement Notes

Verify the specific suffix '17' against the manufacturer's current datasheet to confirm pinout and mechanical dimensions. Ensure the 80 Ohm ESR requirement matches the circuit design. Confirm that the 4-SOJ package footprint aligns with the PCB layout specifications before finalizing procurement.

Crystals Selection Notes

Select this component when a precise 18.432 MHz reference is required for digital systems. The ±10 ppm tolerance suits applications needing stable timing without high-cost oven-controlled oscillators. The 18 pF load capacitance is standard for many microcontrollers, simplifying circuit design compared to non-standard values.

Crystals Part Context

This part belongs to the SXT834 series of plastic surface-mount crystals from Suntsu Electronics. The series offers various frequencies in compact packages suitable for space-constrained electronics. The 4-SOJ form factor provides a balance between size and thermal performance for general-purpose timing applications.

Crystals Replacement Considerations

Direct substitutes must match the 18.432 MHz frequency, 18 pF load capacitance, 80 Ohm ESR, and 4-SOJ package dimensions. Verify that alternative manufacturers offer identical ±10 ppm tolerance and compatible operating temperature ranges to ensure functional equivalence.
