CST7.8/5.3/9.8-3S4

Overview

The Ferroxcube CST7.8/5.3/9.8-3S4 is a cylindrical ferrite core designed for cable shielding applications. It utilizes 3S4 material composition and provides an impedance of 50 Ohms at 100 MHz. The component features a single hole with an inner diameter of 5.3 mm, an external width of 7.8 mm, and a length of 9.8 mm.

Feature Summary

• Cylindrical geometry optimized for slip-on cable installation
• Engineered to provide 50 Ohm impedance at 100 MHz
• Constructed from 3S4 ferrite material for EMI suppression

Applications

• Suppression of electromagnetic interference on Ethernet cables
• Noise filtering for networking cables
• Common mode noise reduction in data transmission lines

Procurement Notes

Verify the specific suffix '3S4' matches the required frequency response characteristics. Confirm that the 5.3 mm inner diameter accommodates the target cable bundle without excessive clearance. Ensure compliance with RoHS3 regulations as indicated by manufacturer documentation.

Selection Notes

Select this part when a low-profile cylindrical shield is required for small-diameter cables. The 50 Ohm impedance specification targets high-frequency noise typical in digital communication interfaces. Compare physical dimensions against available space constraints on the PCB or cable assembly.

Part Context

This component belongs to the CST series of cylindrical ferrite cores manufactured by Ferroxcube. These cores are distinct from split-ring types as they are solid cylinders intended for sliding onto existing cables rather than clamping around them.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation.
