CT0402CSF-9N0J

Fixed Inductors Overview

The CT0402CSF-9N0J is a surface-mount wire-wound inductor from Central Technologies, designed for general-purpose applications. It features a ceramic core and operates within a temperature range of -40°C to +125°C. The component has a nominal inductance of 9 nH with a tolerance of ±5%. Key electrical specifications include a maximum DC resistance of 0.1 Ω and a self-resolved frequency of 250 MHz. It is RoHS compliant and contains no lead.

Fixed Inductors Feature Summary

• Utilizes a wire-wound construction on a ceramic core for stable inductance.
• Designed for high-current applications within the 0603 form factor.
• Compliant with RoHS standards and free of lead.

Fixed Inductors Applications

• High current inductor circuits
• General purpose RF filtering
• Surface mount PCB assembly

Fixed Inductors Procurement Notes

Verify the specific package dimensions against the official datasheet to ensure compatibility with automated pick-and-place equipment. Confirm that the ±5% tolerance code 'J' matches the circuit requirements. Check for RoHS compliance documentation if required by regulatory standards. Ensure the operating temperature range of -40°C to +125°C suits the environmental conditions of the final application.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 9 nH is required for high-frequency signal integrity. The ceramic core offers stability compared to iron powder alternatives. Consider the 0.1 Ω DC resistance for power loss calculations in high-current paths. The 0603 footprint allows for compact board layouts where space is limited.

Fixed Inductors Part Context

This part belongs to the CT0402CSF series of wire-wound chip inductors manufactured by Central Technologies. The series covers a wide range of inductance values from 1.6 nH to 390 nH. These components are characterized by their open structure and ceramic core, distinguishing them from shielded multilayer variants.

Fixed Inductors Replacement Considerations

Cross-reference with other 9 nH ±5% inductors in the 0603 package. Verify that substitute parts match the 0.1 Ω DC resistance and 250 MHz self-resonant frequency limits. Ensure the replacement also supports the -40°C to +125°C operating range.
