FSRB100030RTB00B

Overview

The FSRB100030RTB00B is a solid ferrite cable core manufactured by Murata Electronics, designed for electromagnetic interference suppression on flat ribbon cables. It exhibits an impedance of 170 Ohms at a test frequency of 100 MHz. The component features a toroidal geometry with an inside diameter of 6 mm, an outside diameter of 10 mm, and a length of 30 mm. Constructed from RT material, it operates within a temperature range of -25°C to +85°C. The unit weighs approximately 1.7 grams and is supplied in bulk packaging.

Feature Summary

• Provides high impedance attenuation for common-mode noise on flat ribbon cables
• Solid construction ensures mechanical stability during installation
• Optimized magnetic properties for effective EMI suppression at 100 MHz

Applications

• Suppression of electromagnetic interference on flat ribbon cables
• Signal integrity enhancement in digital data transmission lines
• Noise reduction in computer peripheral interconnects

Procurement Notes

Verify the specific impedance requirement of 170 Ohms at 100 MHz against your design specifications. Confirm that the 6 mm inner diameter accommodates the target cable bundle thickness. Ensure the operating environment remains within the -25°C to +85°C thermal limits defined by the manufacturer. Check for RoHS compliance status if required by your assembly standards.

Selection Notes

Select this component when flat cable geometry is fixed and standard through-hole cores do not fit. The 170 Ohm impedance offers a balance between attenuation and signal loss for typical digital signals. Consider the physical dimensions carefully to ensure the cable can pass through the 6 mm aperture without excessive strain or deformation during routing.

Part Context

This part belongs to the FSRC/FSRB series of solid ferrite cores from Murata Electronics. These components are specifically engineered for suppressing high-frequency noise on multi-conductor flat cables. The RT material designation indicates a specific magnetic permeability grade suitable for general-purpose EMI suppression applications in consumer and industrial electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs before attempting substitution with generic ferrite cores, as impedance profiles and material compositions may differ significantly.
