Procurement Notes

Verify the specific tolerance code suffix when ordering, as it determines the exact inductance variance. Confirm RoHS compliance status, as some variants may differ. Ensure the selected part matches the required DC resistance and current ratings for the target circuit design before finalizing procurement.

Selection Notes

Select this component for applications requiring a compact 0402 footprint with moderate current handling capabilities. Consider the low inductance value suitable for high-frequency operations. Evaluate the thermal environment to ensure operation remains within the specified -40°C to +125°C range during system integration.

Part Context

This part belongs to the CT0402CSF series from Central Technologies, which offers fixed inductors ranging from 1.6 nH to 390 nH. The series provides various tolerance options including ±2%, ±5%, ±10%, and ±20%. These components are designed for surface mount technology in space-constrained electronic assemblies.

Replacement Considerations

Direct substitutes include other CT0402CSF series variants with identical electrical parameters but different inductance values, such as CT0402CSF-5N6J or CT0402CSF-4N7J, provided the circuit allows for inductance adjustment.
