CST28/16/20-4S2

Overview

The Ferroxcube CST28/16/20-4S2 is a tubular ferrite core designed for cable suppression applications. It utilizes the 4S2 material composition to provide high impedance characteristics across a broad frequency spectrum, effectively attenuating electromagnetic interference on cables. The component features a cylindrical geometry with an internal diameter of 7.9 mm and an external diameter of 28 mm. This physical configuration allows it to be freely suspended over wires without requiring additional mounting hardware or clamps.

Feature Summary

High impedance performance provided by 4S2 material composition
Tubular design enables free suspension over cables
Broadband electromagnetic interference suppression capabilities

Applications

Cable noise suppression in electronic assemblies
Electromagnetic compatibility enhancement for wiring harnesses
Interference filtering for signal and power lines

Procurement Notes

Verify that the ordered part number matches the specific 4S2 material designation required for the target frequency range. Confirm compliance with RoHS3 standards as indicated in official documentation. Ensure storage conditions are appropriate for ferrite components to maintain material integrity prior to assembly.

Selection Notes

Select this component when broadband attenuation is required for cables passing through confined spaces where mounting brackets cannot be used. The 4S2 material offers a balance of permeability and resistivity suitable for general-purpose EMI suppression. Evaluate the cable diameter against the 7.9 mm inner bore to ensure a secure fit without excessive clearance.

Part Context

This tubular core belongs to the Ferroxcube CST series, which specializes in snap-on and free-hanging ferrite solutions. Unlike split cores, these solid tubes offer consistent magnetic properties around the entire circumference. The 4S2 material variant is distinct from other compositions like 3F46, optimized specifically for higher frequency absorption rather than low-frequency inductance.
