CT0402CSF-24NJ

Overview

The CT0402CSF-24NJ is a fixed multilayer wire-wound chip inductor manufactured by Central Technologies. It features a nominal inductance of 24 nH with a tolerance of ±5%. The component exhibits a DC resistance (DCR) of 360 mΩ and a self-resonant frequency (SRF) of 2 MHz. It supports a current rating of 375 mA and achieves a quality factor (Q) of 26. The physical dimensions are 1.0 mm x 0.68 mm x 0.55 mm, designed for surface-mount device (SMD) applications.

Feature Summary

• Utilizes a ceramic core wire-wound construction for stable performance
• Designed for surface-mount technology (SMD) integration
• Provides high Q-factor characteristics at low inductance values

Applications

• RF circuit filtering
• Impedance matching networks
• High-frequency signal processing

Procurement Notes

Verify the specific ordering suffix to ensure the correct tolerance and packaging configuration matches project requirements. Confirm that the lead time aligns with production schedules before finalizing orders. Cross-reference the manufacturer's latest documentation to validate RoHS compliance status and environmental certifications. Ensure storage conditions meet the specified humidity and temperature limits to maintain component integrity prior to assembly.

Selection Notes

Select this component when a compact SMD inductor with low inductance and high Q-factor is required. The 0402 footprint suits space-constrained designs. Verify that the operating current does not exceed the rated limit to prevent saturation. Consider the self-resonant frequency to ensure operation remains below the resonance point for intended filter or matching applications.

Part Context

This part belongs to the CT0402CSF series of wire-wound chip inductors from Central Technologies. The series offers various inductance values within the 0402 package size. These components are engineered for general-purpose RF and high-frequency applications where small form factors and reliable electrical performance are critical.

Replacement Considerations

Direct substitutes include other 24 nH ±5% inductors in the 0402 package with comparable DCR and current ratings. Verify pin compatibility and thermal characteristics when replacing. Check datasheets for equivalent SRF and Q-factor specifications to maintain circuit performance.
