Crystals Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with the target PCB footprint and reflow soldering profiles. Cross-reference the part number with authorized distributors to obtain current availability status and lead times, as inventory levels for surface-mount crystals can fluctuate rapidly based on production schedules.

Crystals Selection Notes

Select this component when a 24.576 MHz reference is required in a compact surface-mount form factor. The HC-49/US SMD package offers a balance between size and mechanical stability. Consider the ±30 ppm tolerance and 30 Ohm ESR limits relative to the system's clock accuracy requirements. Verify that the 18 pF load capacitance matches the circuit design to ensure oscillation at the specified frequency without external trimming components.

Crystals Part Context

This part belongs to Suntsu Electronics' line of surface-mount crystals, specifically utilizing the HC-49/US SMD package style. These components are engineered for high-volume manufacturing environments where space constraints necessitate surface-mount technology over through-hole alternatives. The series provides reliable frequency stability for consumer electronics and industrial applications requiring standardized clock frequencies.

Crystals Replacement Considerations

Direct substitutes must match the 24.576 MHz frequency, HC-49/US SMD package dimensions, 18 pF load capacitance, and ≤30 Ohm ESR. Verify thermal stability ratings align with the application environment. Check pinout compatibility and solderability standards before integration.
