FSRH044C00RNB00B

Overview

The Murata Electronics FSRH044C00RNB00B is a solid free-hanging ferrite cable core designed for electromagnetic interference suppression. It exhibits an impedance of 40 ohms at a frequency of 100 MHz. The component features an inner diameter of 1.5 mm, an outer diameter of 3.6 mm, and an external length of 3.0 mm. It operates within a frequency range of 100 kHz to 1 GHz.

Feature Summary

• Solid construction provides stable magnetic properties for consistent noise attenuation.
• Free-hanging design allows for easy installation on existing cables without disassembly.

Applications

• Suppression of common mode noise in flat ribbon cables
• EMI filtering for high-speed digital signal lines
• Noise reduction in internal wiring of electronic equipment

Procurement Notes

Verify the specific part number against official Murata documentation to ensure accuracy, as distributor listings may contain errors or outdated information. Confirm that the solid core type matches the application requirements for cable diameter and impedance characteristics before finalizing procurement decisions.

Selection Notes

Select this component when a compact, solid ferrite core is required for cables with a 1.5 mm inner diameter. Ensure the target application falls within the specified 100 kHz to 1 GHz frequency range where the 40 ohm impedance provides effective attenuation. Consider physical constraints regarding the 3.6 mm outer diameter during layout planning.

Part Context

This component belongs to the FSRH series of ferrite cable cores manufactured by Murata Electronics. These cores are engineered for general-purpose electromagnetic interference suppression in various electronic assemblies. The solid material composition distinguishes it from split-core alternatives, offering permanent magnetic coupling around the conductor.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative ferrite cores based on matching impedance curves, dimensional constraints, and material specifications if direct replacement is necessary.
