CSF38/12/25-3S4-S

Overview

The Ferroxcube CSF38/12/25-3S4-S is a flat cable ferrite core designed for electromagnetic interference suppression. It utilizes the 3S4 magnetic material and features a split-core construction for easy installation over existing cables. The component has an impedance of 196 ohms at 100 MHz and measures 26.8 mm in length. Key dimensions include a width of 38.5 mm, height of 12.1 mm, and depth of 25.4 mm.

Feature Summary

• Split-core design allows installation on pre-existing flat cables without disconnection
• High impedance performance at 100 MHz for effective noise attenuation
• Constructed with 3S4 ferrite material optimized for EMI suppression

Applications

• Suppression of electromagnetic interference on flat ribbon cables
• Noise filtering in computer peripheral connections
• EMI mitigation in internal bus structures

Procurement Notes

Verify the specific suffix 'S' indicates the split-core variant when ordering. Confirm that the 3S4 material grade matches the required frequency response for the target application. Ensure the physical dimensions align with the flat cable thickness to guarantee proper clamping force and magnetic circuit integrity during assembly.

Selection Notes

Select this component based on the required impedance value of 196 ohms at 100 MHz. The CSF series geometry must accommodate the specific cross-section of the flat cable being treated. Consider the thermal environment and mechanical constraints of the enclosure to ensure the split-core housing fits within the available space without interfering with adjacent components.

Part Context

This part belongs to the CSF series of flat cable cores from Ferroxcube. These components are engineered specifically for suppressing common-mode noise on parallel data lines. The series offers various sizes and material grades to suit different cable widths and frequency requirements.

Replacement Considerations

CSF38/12/25-3S4 is the non-split version of this core; verify if assembly method permits its use. Other CSF series parts may serve as alternatives if impedance and dimensional tolerances match the design requirements.
