CT0402CSF-5N6J

Overview

The CT0402CSF-5N6J is a general-purpose fixed inductor from Central Technologies, designed for surface-mount applications. It features a ceramic core and a wire-wound construction within a compact 0402 rectangular package. The component has a nominal inductance of 5.6 nH with a tolerance of ±5%. Key electrical specifications include a maximum DC resistance of 80 mΩ, a minimum quality factor of 20 at the test frequency, and a self-resonant frequency of 4800 MHz. It supports a maximum rated current of 0.76 A and operates reliably within a temperature range of -40 °C to 125 °C.

Feature Summary

• Utilizes a ceramic core and wire-wound architecture for stable RF performance
• Optimized for high-current applications with a 0.76 A rating
• Surface-mount design facilitates automated assembly in compact circuits

Applications

• RF inductor circuits
• High current inductor applications
• General purpose signal filtering

Procurement Notes

Verify RoHS compliance status, as datasheets indicate both compliant and non-compliant variants exist within the series. Confirm lead-free soldering requirements against specific project standards. Ensure the ordering suffix matches the required tolerance code (J for ±5%). Validate that the 0402 footprint aligns with the PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a low inductance value near 5.6 nH is required for high-frequency signal paths. The 0.76 A current rating makes it suitable for power integrity or bias networks where higher currents are present compared to standard multilayer types. Consider the 80 mΩ DC resistance impact on voltage drop if used in low-voltage supply lines.

Part Context

This part belongs to the CT0402CSF series of wire-wound chip inductors manufactured by Central Technologies. The series offers a wide range of inductance values from 1.6 nH to 390 nH in the 0402 package. These components are distinguished by their ceramic core construction, which provides better thermal stability and higher current handling capabilities than typical multilayer inductors in the same form factor.

Replacement Considerations

Direct substitutes may include other 0402 ceramic-core wire-wound inductors with identical 5.6 nH inductance and ±5% tolerance. Verify that alternative parts meet or exceed the 0.76 A current rating and 4800 MHz self-resonant frequency. Check compatibility with RoHS3 compliance requirements if the original unit is confirmed compliant.
