Crystals Procurement Notes

Verify the specific suffix codes against official Suntsu documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with existing PCB footprint requirements for the 2520 four-pad form factor. Cross-reference datasheet parameters for ESR and load capacitance to validate circuit design integrity before final procurement decisions.

Crystals Selection Notes

Select this component when space constraints necessitate a 2.5mm x 2.0mm footprint while maintaining industrial temperature reliability. The four-terminal design offers superior electromagnetic interference shielding compared to two-terminal alternatives. Consider the 80 Ohm ESR limit for oscillator circuit matching and ensure the 20 pF load capacitance aligns with the host microcontroller or RF transceiver specifications.

Crystals Part Context

This part belongs to the SXT224 series of surface-mount crystals from Suntsu Electronics. The series is characterized by its compact ceramic package and suitability for applications requiring precise timing in small form factors. It serves as a critical clock source for digital and RF circuits where size and thermal performance are primary design drivers.

Crystals Replacement Considerations

Direct substitutes must match the 22.1184 MHz frequency, 20 pF load capacitance, 80 Ohm ESR, and 2520 four-pad package. Verify that alternative components support the -40°C to +85°C operating range and ±50 ppm tolerance to maintain system timing accuracy.
