Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact tolerance and stability ratings. Ensure the package dimensions match the intended PCB land pattern. Confirm that the operating temperature range aligns with the final product environment requirements before placing orders.

Crystals Selection Notes

Select this component when a stable 18.432 MHz reference is required for digital logic or communication interfaces. The 18 pF load capacitance must match the oscillator circuit design. Consider the ±10 ppm stability for applications requiring moderate precision without the cost of higher-grade oscillators.

Crystals Part Context

This part belongs to Suntsu's SXT series of surface-mount crystals. The series focuses on mid-market frequency control solutions. The model number indicates specific electrical characteristics including frequency, load capacitance, and package type within the manufacturer's catalog structure.

Crystals Replacement Considerations

Direct substitutes require matching 18.432 MHz frequency, 18 pF load capacitance, and 4-SMD package. Verify ESR compatibility with existing oscillator circuits. Check if alternative brands offer tighter stability if system requirements exceed ±10 ppm.
