• Stable frequency output with tight tolerance specifications
• Lead-free construction supporting high-temperature reflow soldering

Crystals Applications

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

Crystals Procurement Notes

Verify the specific suffix '12.000M' to confirm the 12 MHz frequency variant, as the SXT2247AA38 series includes multiple frequency options such as 24 MHz or 32 MHz. Ensure the load capacitance requirement of your oscillator circuit matches the 7 pF specification to maintain accuracy. Confirm that the 120 Ohm ESR aligns with your driver circuit capabilities. Request the official datasheet from Suntsu Electronics for final electrical parameter validation before integration.

Crystals Selection Notes

Select this component when a 12 MHz reference is required in a small form factor. The 4-SMD package suits space-constrained PCB layouts. Consider the ±50 ppm stability for general-purpose timing rather than high-precision applications. Verify compatibility with the target oscillator circuit's drive level requirements, typically between 1 μW and 100 μW for this series.

Crystals Part Context

This part belongs to the SXT2247 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies ranging from 8 MHz to 54 MHz in similar packages. These components are engineered for consumer electronics and communication devices, emphasizing low power consumption and reliable performance in compact designs.

Crystals Replacement Considerations

Direct substitutes must match the 12 MHz frequency, 7 pF load capacitance, and 4-SMD package dimensions. Cross-reference with other manufacturers offering 12 MHz SMD crystals with comparable ESR and stability ratings. Ensure thermal and mechanical specifications align with the original design constraints.
