Fixed Inductors Procurement Notes

Verify the specific ordering suffix when placing orders, as tolerance codes may vary. Confirm RoHS compliance status prior to procurement, as lead-free variants exist within the series. Ensure the selected part matches the required inductance value and current rating for the target circuit design. Cross-reference datasheets for thermal derating curves if operating near maximum temperature limits.

Fixed Inductors Selection Notes

Select this component for applications requiring low inductance values in compact footprints. Consider the 0402 package size constraints against available board space. Evaluate the self-resonant frequency to ensure it exceeds the operational frequency of the circuit. Compare the maximum rated current against peak load requirements to prevent saturation or overheating during operation.

Fixed Inductors Part Context

This part belongs to the CT0402CSF series of wire-wound chip inductors manufactured by Central Technologies. The series offers various inductance values ranging from sub-nanohenry to higher ranges, all housed in the 0402 surface mount package. These components are engineered for use in RF and general-purpose electronic circuits where small form factors are critical.

Fixed Inductors Replacement Considerations

Compatible substitutes include other 0402 wire-wound inductors with 2.2 nH nominal inductance and similar current ratings. Verify that alternative parts meet the same self-resonant frequency and DC resistance specifications to maintain circuit performance.
