FSRH070140RN000B

Overview

The Murata Electronics FSRH070140RN000B is a solid ferrite cable core designed for electromagnetic interference suppression. It features an RN material composition and provides an impedance of 82 ohms at 100 MHz. The component has a circular geometry with an inner diameter of 4 mm, an outer diameter of 7 mm, and a length of 14 mm. It operates within a frequency range of 100 kHz to 1 GHz. The part is packaged in bulk and is currently obsolete.

Feature Summary

• Solid construction eliminates the need for assembly hardware
• Free-hanging installation method allows flexible cable routing
• RN material composition supports high-frequency noise attenuation

Applications

• Electromagnetic interference filtering on ribbon cables
• Signal integrity enhancement in high-speed data lines
• Common mode noise suppression in electronic assemblies

Procurement Notes

This component is officially classified as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or approved replacement parts. Do not assume current production status. Confirm RoHS compliance and lifecycle status through official datasheets before integration into new designs.

Selection Notes

Select this part when a solid, non-split ferrite core is required for free-hanging cable applications. Ensure the cable diameter fits within the 4 mm inner diameter constraint. Verify that the 82 ohm impedance at 100 MHz aligns with the target noise spectrum. Consider the RN material properties for the specific frequency range of interest.

Part Context

The FSRH series represents Murata's line of solid ferrite cores for cable noise suppression. This specific model belongs to the FSRH family, characterized by its fixed dimensions and solid body design. It serves as a passive component for mitigating high-frequency electromagnetic disturbances on conductors without requiring additional mounting structures.

Replacement Considerations
