CT0603CTF-4N3H

Fixed Inductors Overview

The CT0603CTF-4N3H is a fixed wire-wound chip inductor manufactured by Central Technologies, designed for surface-mount applications. It features a ceramic core and operates within the standard 0603 package footprint. The component provides a nominal inductance of 4.3 nH with a tolerance code 'H' indicating ±3% accuracy. It exhibits a maximum DC resistance of 76 mΩ and supports a maximum rated current of 1.2 A. The device is RoHS compliant and suitable for high-frequency circuits requiring low-inductance performance.

Fixed Inductors Feature Summary

• Wire-wound construction on a ceramic core for stable RF performance
• Low DC resistance to minimize power loss in high-current paths
• Surface-mount design compatible with automated assembly processes

Fixed Inductors Applications

• RF matching networks
• High-frequency signal filtering
• Impedance matching circuits

Fixed Inductors Procurement Notes

Verify the specific tolerance suffix when ordering, as the base model number requires the tolerance code to be specified. Confirm that the 0603 package dimensions align with the target PCB layout. Ensure the operating temperature range meets the application requirements. Check for RoHS compliance documentation if required by regulatory standards. Validate the maximum current rating against the circuit's peak load conditions.

Fixed Inductors Selection Notes

Select this component for applications requiring precise, low-value inductance in compact spaces. The 4.3 nH value is ideal for ultra-high-frequency designs where parasitic effects must be minimized. Consider the 1.2 A current rating for power handling needs. The ceramic core offers stability compared to air-core alternatives. Evaluate the 76 mΩ resistance impact on overall circuit efficiency.

Fixed Inductors Part Context

This part belongs to the CT0603CTF series of wire-wound chip inductors from Central Technologies. The series covers a wide range of inductance values from 1.6 nH to 390 nH in the 0603 package. These components are engineered for general-purpose use in RF and high-speed digital circuits, offering a balance between size, performance, and cost-effectiveness.

Fixed Inductors Replacement Considerations

Direct substitutes include other 4.3 nH ±3% inductors in the 0603 package with similar current ratings. Cross-reference parameters such as DC resistance and self-resonant frequency to ensure compatibility. Verify that alternative parts maintain the same ceramic core construction for comparable Q-factor performance.
