Crystals Procurement Notes

Verify the specific suffix CA27 against official Suntsu documentation to confirm the exact frequency tolerance and stability specifications. Ensure the 4-SOJ package dimensions match the target PCB footprint requirements. Cross-reference the ESR value of 60 Ohms with circuit design constraints to guarantee proper oscillation startup conditions.

Crystals Selection Notes

Select this component when a 29.4912 MHz frequency is required with moderate precision. The 4-SOJ package offers a balance between size and solderability for surface-mount processes. Consider the ±25 ppm tolerance relative to system clock accuracy needs before finalizing the design integration.

Crystals Part Context

This part belongs to the Suntsu SXT83418 series of surface-mount crystals. The series includes variants with different tolerances and packages, such as EE27 and FD27 suffixes. These components are engineered for general-purpose frequency control in consumer and industrial electronics requiring stable reference clocks.

Crystals Replacement Considerations

Compatible substitutes include SXT83418EE27-29.4912M and SXT83418FD27-29.4912M from the same manufacturer. Verify that alternative parts maintain the 4-SOJ package form factor and 18 pF load capacitance to ensure electrical compatibility without PCB redesign.
