CT0402CSF-3N3K

Fixed Inductors Overview

The CT0402CSF-3N3K is a fixed surface-mount inductor from Central Technologies, designed for general-purpose applications. It features a ceramic core and wire-wound construction within a standard 0402 package. The nominal inductance is 3.3 nH with a tolerance of ±10%. Key electrical specifications include a maximum DC resistance of 60 mΩ, a self-resonant frequency of 6 GHz, and a minimum quality factor of 16 at the rated inductance. The component supports a maximum rated current of 0.38 A and operates reliably within a temperature range of -55 °C to +125 °C.

Fixed Inductors Feature Summary

• Utilizes a ceramic core and wire-wound architecture for stable RF performance
• Offers high self-resonant frequency suitable for ultra-high-frequency circuits
• Compliant with RoHS standards and lead-free manufacturing requirements

Fixed Inductors Applications

• RF circuit design
• General-purpose inductive filtering
• High-frequency signal processing

Fixed Inductors Procurement Notes

Verify the specific tolerance suffix (K) corresponds to the required ±10% accuracy for your design. Confirm that the 0402 footprint matches your PCB layout constraints. Ensure the operating environment stays within the specified -55 °C to +125 °C range to maintain component integrity. Cross-reference the 60 mΩ DCR limit against your power budget requirements.

Fixed Inductors Selection Notes

Select this component when a compact 0402 form factor is required for sub-nanohenry inductance values. It is appropriate for designs needing a ceramic core for stability rather than air-core flexibility. Consider the 60 mΩ DC resistance impact on series resistance if low-loss paths are critical. Evaluate the 0.38 A current rating against peak load conditions to prevent saturation or thermal issues.

Fixed Inductors Part Context

This part belongs to the CT0402CSF series of wire-wound chip inductors manufactured by Central Technologies. The series provides various inductance values ranging from 1.0 nH to 120 nH in the same 0402 package. It serves as a standardized solution for space-constrained RF applications requiring precise, small-value inductance.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include CT0402CSF-3N6J (3.6 nH, ±5%) and CT0402CSF-2N7J (2.7 nH, ±5%). For identical 3.3 nH values but different tolerances, consider CT0402CSF-3N3G (±2%) or CT0402CSF-3N3J (±5%). Verify package compatibility and parameter alignment before substitution.
