CST8.3/3.5/10-3S4

Overview

The Ferroxcube CST8.3/3.5/10-3S4 is a cylindrical ferrite core designed for electromagnetic interference suppression. It features an outer diameter of 8.3 mm, an inner diameter of 3.5 mm, and a length of 10 mm. The component utilizes 3S4 material composition, providing a specific impedance of 96 ohms at 100 MHz. This solid core configuration supports effective noise attenuation in high-frequency applications.

Feature Summary

• Solid cylindrical geometry optimized for cable clamping
• High specific impedance for broadband noise suppression
• Compatible with standard cable shielding applications

Applications

• Cable EMI suppression
• Signal line noise filtering
• Data bus interference mitigation

Procurement Notes

Verify the complete part number including the suffix to ensure correct material grade and dimensional tolerances. Confirm RoHS compliance status if required by your manufacturing standards. Check for obsolescence notices as distributor listings may indicate obsolete status for this specific variant. Ensure compatibility with existing cable diameters before procurement.

Selection Notes

Select this core based on the required impedance value at the target frequency. The 96 ohm rating at 100 MHz suits general-purpose digital signal lines. Verify that the 3.5 mm inner diameter accommodates the cable bundle without excessive force. Consider thermal constraints if the application involves high current carrying cables nearby.

Part Context

This component belongs to the Ferroxcube cylindrical ferrite core series. These cores are distinct from toroidal or split designs, offering a solid structure for permanent installation on cables. The 3S4 material provides a balance of permeability and resistivity suitable for common mode noise reduction in electronic equipment.

Replacement Considerations

Direct substitutes include other cylindrical cores with identical dimensions (8.3x3.5x10 mm) and similar impedance characteristics. Verify material composition matches 3S4 for equivalent frequency response. Alternative manufacturers may offer comparable parts but require impedance curve validation.
