CST9.5/4.8/10-4S2

Overview

The Ferroxcube CST9.5/4.8/10-4S2 is a cylindrical ferrite core designed for EMI suppression in cable applications. It utilizes the 4S2 material composition, providing an impedance of 80 ohms at 100 MHz. The component features a tubular design with free-hanging installation capabilities. Key physical dimensions include an outer diameter of 9.5 mm, an inner diameter of 4.75 mm, and a length of 10.4 mm. This configuration allows it to be clamped directly onto cables to attenuate high-frequency noise.

Feature Summary

• Provides electromagnetic interference suppression through high impedance characteristics
• Utilizes 4S2 ferrite material for effective noise attenuation
• Features a cylindrical tubular geometry suitable for direct cable mounting

Applications

• High-frequency noise suppression on data cables
• EMI filtering for power supply lines
• Signal integrity enhancement in electronic assemblies

Procurement Notes

Verify the specific impedance rating and material grade against project requirements before procurement. Confirm that the internal diameter accommodates the target cable bundle without excessive force. Ensure compliance with relevant environmental regulations such as RoHS if applicable to the final product deployment.

Selection Notes

Select this component when a compact, snap-on ferrite solution is required for cables up to 4.75 mm in diameter. The 4S2 material offers a balance of permeability and resistivity suitable for general-purpose EMI suppression. Consider the physical length and outer diameter to ensure adequate clearance within the enclosure or housing.

Part Context

This part belongs to the Ferroxcube CST series of cable shields and ferrite cores. These components are engineered to suppress common-mode currents on cables, thereby reducing radiated emissions. The series offers various dimensions and materials to match different cable sizes and frequency ranges.

Replacement Considerations

Check for alternative parts with identical 4.75 mm inner diameter and similar impedance profiles. Verify that any substitute maintains the same physical envelope (9.5 mm OD, 10.4 mm length) to fit existing mechanical constraints.
