CMS2-5.6/3/4.8-4S2

Common Mode Chokes Overview

The Ferroxcube CMS2-5.6/3/4.8-4S2 is a surface-mount common mode choke utilizing 4S2 soft ferrite material. It features a dual-conductor design within a single magnetic block, providing an impedance of 35 Ohms at 100 MHz and 21 Ohms at 25 MHz. The component has a DC resistance of 600 µOhm and dimensions of 5.6 mm length, 3.0 mm width, and 4.8 mm height.

Common Mode Chokes Feature Summary

• Dual-conductor configuration integrated into a single soft-ferrite block for compact layout
• High impedance performance in the 25 MHz to 100 MHz frequency range
• Surface-mount package designed for automated assembly processes

Common Mode Chokes Applications

• Common mode noise suppression in high-speed digital data lines
• EMI filtering for USB and other peripheral interfaces
• Signal integrity protection in telecommunications equipment

Common Mode Chokes Procurement Notes

Verify the specific suffix designation when ordering, as variants such as -Z may indicate different packaging or tape-and-reel configurations compared to the standard part number. Confirm that the 4S2 material grade aligns with the required frequency response characteristics for the target application environment.

Common Mode Chokes Selection Notes

Select this component when space constraints require a low-profile surface-mount solution for differential line filtering. Ensure the operating current remains within limits compatible with the 600 µOhm DC resistance to prevent excessive thermal rise. Validate that the 35 Ohm impedance at 100 MHz meets the specific EMI attenuation requirements of the circuit.

Common Mode Chokes Part Context

This component belongs to the Ferroxcube CMS series of surface-mount common mode chokes. These devices are engineered to suppress electromagnetic interference on multiple conductors simultaneously. The 4S2 material provides optimized magnetic properties for high-frequency noise absorption while maintaining stability under varying operational conditions.

Common Mode Chokes Replacement Considerations

Compatible substitutes include the CMS2-5.6/3/8.9-4S2, which shares the same footprint but offers different magnetic characteristics due to its taller profile. Verify dimensional compatibility and impedance curves before substituting to ensure equivalent noise suppression performance.
