Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer's official documentation to ensure compatibility with required frequency tolerances and packaging formats. Confirm that the 4-SMD no-lead footprint matches the target PCB layout specifications. Ensure that the selected variant meets the thermal requirements for the intended operating environment, particularly regarding the upper temperature limit of 85°C.

Crystals Selection Notes

Select this component when a stable 18.432 MHz reference is required for surface-mount assembly. Consider the ±30 ppm tolerance for general-purpose digital logic or communication interfaces where high-precision oscillators are not mandatory. Evaluate the 12 pF load capacitance requirement against the host circuit's input capacitance to ensure proper oscillation startup and maintenance.

Crystals Part Context

This part belongs to the C2E series of surface-mount crystals from Aker Technology Corp. The series offers various frequency options within a compact 3.2mm x 2.5mm footprint.
