CT0603CTF-2N2J

Fixed Inductors Overview

The CT0603CTF-2N2J is a surface-mount wire-wound inductor from Central Technologies, designed for high-frequency applications. It features a nominal inductance of 2.2 nH with a tolerance of ±5%. The component utilizes a ceramic core and operates within a temperature range of -40°C to 125°C. Key electrical specifications include a maximum DC resistance of 0.046 Ω, a self-resonant frequency of 11 GHz, and a rated current of 1.6 A. The unit is RoHS compliant and housed in a standard 0603 package.

Fixed Inductors Feature Summary

• Wire-wound construction on a ceramic core for stable high-frequency performance
• High current handling capability suitable for power supply filtering
• Compact 0603 surface-mount footprint for space-constrained designs

Fixed Inductors Applications

• RF circuit impedance matching networks
• DC-DC converter output filtering
• High-speed digital signal line termination

Fixed Inductors Procurement Notes

Verify the specific suffix code (e.g., J for ±5% tolerance) against the required design specification before ordering. Confirm that the 0603 package dimensions align with the PCB land pattern. Ensure the operating environment does not exceed the 125°C maximum junction temperature rating. Check for RoHS compliance requirements if applicable to the final assembly standards.

Fixed Inductors Selection Notes

Select this component when a very low inductance value near 2.2 nH is required for RF or high-speed applications. The 1.6 A current rating makes it suitable for power stages where parasitic inductance management is critical. Compare the 11 GHz self-resonant frequency against the target operating frequency to ensure effective inductive behavior. Consider the 0.046 Ω DCR impact on efficiency if used in low-voltage power rails.

Fixed Inductors Part Context

This part belongs to the CT0603CTF series of fixed wire-wound chip inductors manufactured by Central Technologies. The series offers various inductance values ranging from 1.6 nH to higher limits, all sharing the same 0603 physical footprint. These components are engineered for general-purpose use in both RF and power electronics, providing a balance between size, current capacity, and inductance precision.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 2.2 nH inductance, 0603 package, and similar current ratings. Verify that alternative manufacturers offer comparable self-resonant frequencies above 10 GHz. Ensure the replacement part maintains the same tolerance class and thermal characteristics.
