CSF38/12/25-3S4

Overview

The Ferroxcube CSF38/12/25-3S4 is a flat cable ferrite core designed for electromagnetic interference suppression. It features dimensions of 38.1 mm length, 12.1 mm width, and 26.7 mm height. The component utilizes 3S4 material composition and provides an impedance of 196 ohms at 100 MHz. It is certified to UL 94V-0 standards.

Feature Summary

• Provides high impedance for effective noise attenuation on flat ribbon cables
• Constructed with specific ferrite material optimized for broadband interference suppression
• Designed for direct clamping onto flat cable assemblies without additional mounting hardware

Applications

• Suppression of common-mode noise in parallel data buses
• EMI reduction in internal computer and peripheral interconnects
• Noise filtering in flat cable harnesses for industrial control systems

Procurement Notes

Verify the exact part number suffix, as variations such as -S may indicate specific packaging or minor dimensional tolerances distinct from the base model. Confirm that the 196 ohm impedance rating aligns with your target frequency range. Ensure compatibility with the specific thickness and width of the flat cable being treated to guarantee proper mechanical fit and magnetic coupling efficiency.

Selection Notes

Select this component when addressing EMI issues specifically on flat ribbon cables rather than round wires. The 196 ohm impedance value is suitable for higher frequency noise suppression compared to lower impedance alternatives. Consider the physical clearance required around the cable bundle to accommodate the core's internal aperture dimensions during assembly.

Part Context

This component belongs to the CSF series of flat cable cores manufactured by Ferroxcube. These cores are engineered specifically for suppressing electromagnetic interference on multi-conductor flat cables. The series offers various impedance levels and material compositions to suit different frequency ranges and application requirements.

Replacement Considerations

Direct substitutes include the CSF38/12/25-3S4-S variant, which shares identical electrical characteristics but may differ in packaging or minor tolerance specifications. Verify dimensional compatibility before substitution.
