FSRC120120RXB00B

Overview

The Murata FSRC120120RXB00B is a solid ferrite cable core designed for electromagnetic interference suppression. It exhibits an impedance of 59 Ohms at 100 MHz. The component features free-hanging mounting with specific dimensional constraints: inner dimensions of 8.00 mm width by 0.70 mm height, and outer dimensions of 11.50 mm width by 3.00 mm height. It operates within a temperature range of -25°C to +85°C and utilizes RX material composition.

Feature Summary

• Solid ferrite construction for flat cable applications
• Free-hanging mounting configuration
• Specific impedance characteristics at 100 MHz

Applications

• Flat cable noise suppression
• Electromagnetic interference filtering
• Signal integrity enhancement in electronic assemblies

Procurement Notes

Verify current product status as sources indicate this part may be obsolete. Confirm availability through authorized distributors or direct manufacturer channels. Ensure the RX material specification meets environmental compliance requirements such as RoHS. Cross-reference exact dimensional tolerances against design specifications before procurement to ensure physical compatibility with target cable assemblies.

Selection Notes

Select this component when flat cable geometry matches the specified inner dimensions of 8.00 mm by 0.70 mm. Evaluate the 59 Ohm impedance at 100 MHz against target noise frequencies. Consider the -25°C to +85°C operating range for environmental suitability. Verify that free-hanging installation methods align with mechanical design constraints.

Part Context

This ferrite core belongs to the FSRC series from Murata Electronics, specialized for cable-based EMI suppression. Unlike surface-mount beads, this component targets external cabling. The RX designation indicates specific magnetic material properties optimized for broadband attenuation. It serves as a passive filter element in signal and power lines.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the reported obsolete status, alternative sourcing requires careful validation of dimensional and electrical equivalence with existing inventory or new designs.
