FSRB091080RNB00B

Overview

The Murata FSRB091080RNB00B is a solid ferrite core designed for cable noise suppression. It features a circular shape with an inner diameter of 4.30mm, an outer diameter of 9.00mm, and a length of 8.00mm. The component provides an impedance of 582 Ohms at 100MHz. It is constructed from RN material and supports free-hanging installation. The part complies with RoHS3 standards and carries an EAR99 classification.

Feature Summary

• Solid construction eliminates the need for assembly clips or split mechanisms.
• Free-hanging design allows direct routing of cables through the core aperture.

Applications

• Cable noise suppression in electronic assemblies
• EMI filtering where cables pass through the core during manufacturing

Procurement Notes

Verify the specific ordering suffix to confirm exact physical dimensions and material composition. Confirm that the solid ring design aligns with the assembly process, as it requires cable access before final enclosure closure. Check current availability status as distribution channels may vary.

Selection Notes

Select this component when post-assembly cable insertion is not feasible. Ensure the target cable diameter fits within the 4.30mm inner diameter. Verify that the 582 Ohm impedance at 100MHz meets the specific frequency requirements of the noise source being suppressed.

Part Context

This component belongs to the FSRB series of ferrite cores manufactured by Murata Electronics. It serves as a passive electromagnetic interference suppression element. The solid ring format distinguishes it from clamshell-style alternatives, offering a compact solution for integrated cable management.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate other solid ferrite rings with matching 4.30mm inner diameter and similar impedance characteristics if replacement is required.
