CST17/9.5/13-4S2

Overview

The Ferroxcube CST17/9.5/13-4S2 is a cylindrical ferrite core designed for cable shielding applications. It utilizes 4S2 material, which provides high saturation magnetic induction strength to effectively suppress electromagnetic interference. The component features an inner diameter of 9.5mm and an external diameter of 17.45mm, with a total length of 12.7mm. It exhibits an impedance of 88 Ohms at standard test frequencies, ensuring efficient noise attenuation for single-conductor cables passing through the central aperture.

Feature Summary

• High saturation magnetic induction strength for effective EMI suppression
• Cylindrical geometry optimized for single-hole cable clamping
• 4S2 material composition ensures stable performance under varying conditions

Applications

• Electromagnetic interference filtering on power and signal cables
• Common mode noise suppression in electronic assemblies
• Cable shielding in industrial control systems

Procurement Notes

Verify the specific material grade (4S2) and dimensional tolerances against the official Ferroxcube datasheet before integration. Ensure the inner diameter matches the target cable outer diameter to maintain secure mechanical fit without excessive stress. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this core when high saturation capability is required to prevent core loss during high-current transient events. The 9.5mm bore size dictates compatibility with specific cable gauges. Consider the 88 Ohm impedance characteristic for the target frequency range of interference. Evaluate mechanical constraints regarding the 17.45mm external diameter and 12.7mm length within the enclosure design.

Part Context

This component belongs to the CST series of cylindrical ferrite cores manufactured by Ferroxcube. These cores are distinct from split-core or snap-on types, typically requiring cable insertion prior to assembly. The 4S2 material designation indicates a specific manganese-zinc ferrite formulation optimized for high flux density applications compared to standard low-loss materials.

Replacement Considerations

Direct substitutes must match the 9.5mm inner diameter, 17.45mm outer diameter, and 12.7mm length. Material equivalence requires verifying similar saturation characteristics and impedance curves. Alternative part numbers such as CST17/9.5/13-3S4 may be considered if material properties align with the application requirements.
