CST14/6.4/14-4S2

Overview

The Ferroxcube CST14/6.4/14-4S2 is a tubular ferrite core designed for cable shielding applications. It utilizes the 4S2 material composition, which provides high impedance characteristics suitable for suppressing electromagnetic interference in the frequency range of 10 MHz to 300 MHz. The component features a cylindrical geometry with an inner diameter of 6.4 mm and an outer diameter of 14 mm. It has a length of 14 mm and offers an impedance of 105 ohms at 100 MHz. The core is supplied without coating and is intended for free-hanging installation on cables.

Feature Summary

• High impedance performance for effective suppression of common mode noise in the 10 MHz to 300 MHz frequency band
• Tubular design compatible with standard cable diameters up to 6.4 mm
• Free-hanging construction allows for flexible integration into existing wiring harnesses

Applications

• Suppression of electromagnetic interference in data communication cables
• Noise filtering for power supply lines in electronic equipment
• Common mode choke applications in industrial control systems

Procurement Notes

Verify the specific impedance tolerance and material batch consistency upon receipt. Confirm that the inner diameter matches the target cable outer diameter to ensure proper fit. Check for any physical damage to the ferrite surface that could affect magnetic performance. Ensure compliance with relevant environmental regulations such as RoHS if required by the end application.

Selection Notes

Select this component when high attenuation is required in the VHF/UHF range. The 4S2 material is optimized for frequencies above 10 MHz, making it distinct from lower-frequency materials. Consider the thermal environment as ferrite properties can vary with temperature. Ensure the cable fits securely within the 6.4 mm bore to maintain consistent magnetic coupling.

Part Context

This part belongs to the Ferroxcube CST series of tubular ferrite cores. These components are specifically engineered for cable shielding rather than transformer or inductor winding. The '4S2' suffix denotes the specific manganese-zinc ferrite formulation used, which balances permeability and resistivity for high-frequency noise suppression.

Replacement Considerations

Substitute parts must match the 6.4 mm inner diameter and 14 mm length constraints. Verify that alternative materials offer comparable impedance profiles at 100 MHz. Physical dimensions and mounting style (free-hanging) must remain identical to avoid mechanical redesign.
