• Designed for surface-mount technology using a 4-SMD no-lead package
• Optimized for low power consumption in portable electronic applications

Crystals Applications

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

Crystals Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency tolerance and packaging variant matches the design requirements. Confirm that the load capacitance specification aligns with the host circuit's input capacitance to maintain accurate frequency performance. Check for RoHS compliance status if environmental regulations apply to the final product assembly.

Crystals Selection Notes

Select this component when a 20 MHz reference with moderate stability is required for cost-sensitive designs. Ensure the operating temperature range meets the application environment needs. Compare ESR values against the oscillator circuit's drive level limitations to prevent over-driving the crystal. Validate package dimensions against the PCB footprint constraints.

Crystals Part Context

This part belongs to the SXT22412 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and tolerances in a standardized small outline package. It serves as a passive timing element distinct from active oscillators, requiring an external amplifier circuit to generate a square wave output.

Crystals Replacement Considerations

Direct substitutes must match the 20 MHz frequency, 12 pF load capacitance, and 4-SMD package. Verify that alternative parts meet the same ±50 ppm tolerance and 80 Ohm ESR specifications to ensure circuit compatibility without redesign.
