Applications

• Suppression of noise on flat ribbon cables
• EMI filtering in electronic assemblies requiring solid cores
• High-frequency signal line protection

Procurement Notes

This component is officially designated as End-of-Life (EOL) by Murata Electronics. Verification of current availability through authorized distributors or secondary market sources is essential before integration into new designs. Confirm compliance with RoHS directives via official documentation. Due to discontinuation status, lead times and stock levels are unpredictable; substitute parts should be evaluated immediately to ensure supply chain continuity for production requirements.

Selection Notes

Select this part only if the specific 53 Ohm impedance at 100 MHz aligns with circuit requirements. Verify that the 1.5 mm inner diameter accommodates the target cable bundle without excessive friction. Consider the physical dimensions of 3.6 mm outer diameter and 5 mm length for spatial constraints. Since the item is discontinued, prioritize alternative components with similar electrical parameters and form factors to mitigate future sourcing risks.

Part Context

The FSRH series comprises solid ferrite cores intended for EMI suppression on various cable types. The FSRH044050RNB00B specifically targets flat ribbon applications. Murata Electronics manufactures these components using specialized ferrite materials to achieve consistent performance across the specified frequency spectrum.
