FSRC080090RTB00B

Overview

The FSRC080090RTB00B is a ferrite cable core manufactured by Murata Electronics, designed for noise suppression in electronic circuits. It features an RT material composition (Ni-Zn type) with a permeability of 1600 ± 30% and a Curie temperature of 110 °C. The component provides an impedance of 51 Ohms at a test frequency of 100 MHz. It is specifically engineered for use with flat cables. The operating temperature range spans from -25 °C to +85 °C. The physical dimensions are 8.0 mm in length, 6.0 mm in width, and 9.0 mm in height, with an inner diameter of 2.7 mm and outer diameter of 5.1 mm. The unit weight is approximately 51 mg.

Feature Summary

• Utilizes Ni-Zn ferrite material with high permeability for effective common-mode noise suppression.
• Solid ring core design optimized for clamping onto flat ribbon cables.
• Provides specific impedance characteristics at 100 MHz to attenuate electromagnetic interference.

Applications

• Noise suppression for flat ribbon cables in electronic assemblies
• EMI filtering for signal lines in consumer electronics
• Common-mode choke application for data transmission cables

Procurement Notes

Verify the part number FSRC080090RTB00B against official Murata documentation to confirm current availability status, as some sources indicate this specific variant may be obsolete. Ensure the selected ferrite material (RT) matches the required permeability and temperature characteristics for the target application environment. Cross-reference dimensional specifications with the cable bundle size to ensure proper fitment.

Selection Notes

Select this component when noise suppression is required for flat cables within the specified temperature range. The RT material offers high permeability suitable for lower frequency noise attenuation compared to other materials like RN. Confirm that the inner diameter accommodates the total thickness of the flat cable bundle without excessive force or loose fitment.

Part Context

This component belongs to the FSRC series of ferrite cores produced by Murata Electronics. The series includes various dimensions and material options tailored for different cable types and noise frequencies. The FSRC designation indicates a Ferrite Ring Core, while the suffix codes define specific dimensions, material type, and packaging configuration.

Replacement Considerations

Consult Murata directly for confirmed substitute part numbers, as availability varies. Alternative ferrite cores with similar impedance at 100 MHz and compatible inner diameters may serve as functional replacements if exact model matching is not possible.
