Crystals Procurement Notes

Verify the specific suffix 'M' against official Suntsu documentation to confirm packaging configuration and lead finish specifications. Ensure the selected variant matches the required thermal profile for your application environment. Cross-reference the load capacitance value with your oscillator circuit design to guarantee accurate frequency performance. Confirm that the four-terminal layout aligns with your PCB footprint requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a small form factor is critical alongside moderate frequency stability requirements. The 22pF load capacitance must match the host oscillator circuit's input capacitance settings. Consider the -10°C to +60°C operating range suitability for your specific environmental conditions. Evaluate the 50 Ohm impedance against your driver strength capabilities to ensure reliable startup and sustained oscillation.

Crystals Part Context

This part belongs to the SXT324 series, which represents Suntsu's line of 3225-sized, four-pad ceramic-packaged crystals. The series is engineered for applications demanding improved signal integrity through enhanced grounding structures. It complements larger packages by offering similar electrical performance in a reduced physical volume suitable for modern miniaturized electronic designs.

Crystals Replacement Considerations

Direct substitutes require matching the 22.1184 MHz frequency, 22pF load capacitance, and 4-SMD package geometry. Verify that alternative components support the same -10°C to +60°C temperature range and 50 Ohm ESR specifications to maintain circuit compatibility without redesign.
