Crystals Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical characteristics and packaging specifications. Ensure that the selected variant aligns with the required load capacitance and stability parameters for the target circuit design. Cross-reference the part number with current datasheets to validate active lifecycle status and availability constraints before finalizing procurement orders.

Crystals Selection Notes

Select this component when space-constrained layouts require a small footprint while maintaining strict electromagnetic compatibility standards. The four-terminal configuration offers superior grounding capabilities essential for high-frequency radio frequency sections. Consider the fundamental AT-cut design for simplified circuit topology and reduced component count in cost-sensitive or power-efficient wireless implementations.

Crystals Part Context

This model belongs to the SXT224 series of industrial-grade ceramic surface-mount crystals from Suntsu Electronics. The series is engineered for demanding environments where size reduction and signal integrity are critical. The specific 16 MHz variant provides a common clock reference for microcontrollers and communication interfaces requiring precise timing synchronization within tight physical boundaries.

Crystals Replacement Considerations

Direct substitutes include other SXT224 series variants such as SXT2249AA07-16.000M or SXT2249AA38-16.000M, which share identical mechanical dimensions and pinout configurations. Verify that alternative options match the required ±50 ppm stability and 9 pF load capacitance specifications to ensure circuit compatibility.
