FB43-226-RC

Overview

The FB43-226-RC is a solid ferrite core manufactured by Bourns Inc., designed for EMI suppression on cables and wiring. It utilizes material grade 43, providing effective noise reduction in the 40 MHz to 200 MHz frequency range. The component features a circular design with an inner diameter of 1.52 mm (0.060 inches) and an outer diameter of 3.89 mm (0.153 inches). Its physical length measures 6.38 mm (0.251 inches). This free-hanging sleeve type core is intended for direct installation onto conductors.

Feature Summary

• Solid construction for durable cable mounting
• Material grade 43 optimized for high-frequency noise attenuation
• Free-hanging sleeve design for easy wire insertion

Applications

• EMI suppression on data cables
• Noise filtering on power supply wires
• Signal line protection in electronic assemblies

Procurement Notes

Verify the specific suffix RC against current manufacturer documentation to confirm availability status, as some listings indicate this part may be obsolete or discontinued. Ensure the required inner diameter matches the target cable gauge precisely. Cross-reference the material grade 43 specification with the latest datasheet to confirm performance characteristics for the intended operating frequency range.

Selection Notes

Select this component when a compact, solid ferrite solution is required for frequencies between 40 MHz and 200 MHz. The 1.52 mm inner diameter limits usage to smaller gauge wires. Consider the physical dimensions to ensure adequate clearance within the enclosure. Material grade 43 offers a balance of permeability and resistivity suitable for general-purpose EMI suppression tasks.

Part Context

This part belongs to the FB series of ferrite cable cores from Bourns. The FB43 designation indicates the use of manganese-zinc ferrite material grade 43. These components are passive devices used to suppress electromagnetic interference without affecting the signal integrity of the transmitted data or power.

Replacement Considerations

Check for direct substitutes with identical inner diameter and material grade 43 composition. Verify that any replacement maintains the same physical dimensions to fit existing assembly constraints.
