Procurement Notes

This component is classified as obsolete or end-of-life by the manufacturer. Verification of availability through secondary distributors is required. Confirm RoHS compliance status and exact manufacturing date codes prior to procurement, as supply chain continuity is not guaranteed for discontinued parts.

Selection Notes

Select this part when a 50 Ohm impedance at 100 MHz is required for flat ribbon cables with a 1.5 mm inner diameter. Ensure the application environment supports the RN material properties. Verify that the physical dimensions (3.6 mm OD, 4.00 mm length) fit the available space constraints in the target assembly.

Part Context

Part of the FSRH series of solid ferrite cores manufactured by Murata Electronics. This series focuses on providing reliable EMI suppression solutions for various cable types, specifically optimized for flat ribbon configurations in consumer and industrial electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, alternative components must be selected based on matching electrical impedance, physical dimensions, and material characteristics.
