CST9.5/5.1/15-4S2

Overview

The Ferroxcube CST9.5/5.1/15-4S2 is a tubular ferrite core designed for cable shielding applications. It utilizes the proprietary 4S2 material composition, which provides high magnetic permeability and impedance characteristics suitable for suppressing electromagnetic interference (EMI) in the high-frequency range. The component features a cylindrical geometry with a central aperture of 5.1 mm to accommodate various cable diameters. Its external dimensions are defined by a diameter of 9.5 mm and an axial length of 15 mm. This configuration allows for free-hanging installation directly onto cables without requiring additional mounting hardware.

Feature Summary

• Constructed from 4S2 ferrite material optimized for broadband EMI suppression
• Tubular design facilitates direct sliding installation onto cables
• Provides effective common-mode noise attenuation in high-frequency environments

Applications

• Suppression of electromagnetic interference on data communication cables
• Noise filtering for power supply lines in electronic equipment
• Cable shielding in industrial control systems

Procurement Notes

Verify that the ordered part number matches the specific dimensional requirements, particularly the 5.1 mm inner diameter and 15 mm length. Confirm material grade is 4S2 as specified. Ensure compliance with RoHS directives if required by the end application. Cross-reference official datasheets for impedance curves at target frequencies to validate performance suitability.

Selection Notes

Select this component when a compact tubular shield is required for cables up to 5.1 mm in diameter. The 4S2 material offers a balance of permeability and resistivity. Consider the physical length of 15 mm for available space constraints along the cable run. Evaluate the impedance profile against the specific noise spectrum to ensure adequate attenuation.

Part Context

This component belongs to the CST series of tubular ferrite cores manufactured by Ferroxcube. These cores are distinct from split-bead or snap-on types due to their continuous tubular construction. The series is widely used in passive EMI suppression where a robust, non-magnetic housing is not present around the cable itself.
