Crystals Procurement Notes

Verify the specific suffix '48' against the manufacturer's latest datasheet to confirm exact electrical parameters and packaging specifications. Ensure compatibility with the target PCB footprint and reflow soldering profiles. Cross-reference the load capacitance requirement with the host microcontroller or oscillator circuit design to guarantee proper frequency accuracy.

Crystals Selection Notes

Select this component when a compact 2520 footprint is required alongside robust EMI suppression capabilities. The four-pad structure offers superior grounding compared to two-pin alternatives, making it suitable for sensitive RF sections. Consider the ±50 ppm stability limit for applications that do not demand tighter frequency tolerances, balancing cost and performance for general-purpose industrial timing needs.

Crystals Part Context

This part belongs to the SXT224 series of ceramic surface-mount crystals from Suntsu Electronics. The series is engineered for wireless projects where space constraints and signal integrity are critical. The 2520 package size allows for dense PCB arrangements while maintaining industrial durability. The model number indicates specific frequency and tolerance configurations within this standardized product line.

Crystals Replacement Considerations

Direct substitutes must match the 37.400 MHz frequency, 10 pF load capacitance, and 4-SMD no-lead package dimensions. Verify that alternative components support the same -40°C to +85°C operating range and similar ESR values to ensure circuit stability without redesign.
