FB73-287-RC

Overview

The FB73-287-RC is a solid free-hanging ferrite core from the Bourns FB series, designed for cable EMI suppression. It utilizes Type 73 material optimized for operation at 40MHz. The component features a cylindrical geometry with an inner diameter of 0.104 inches (2.64mm), an outer diameter of 0.311 inches (7.89mm), and a length of 0.312 inches (7.92mm). This specific part number indicates the standard packaging suffix.

Feature Summary

• Solid construction provides mechanical stability for cable clamping
• Type 73 material composition targets high-frequency noise attenuation
• Free-hanging design allows direct installation on wires without mounting hardware

Applications

• Cable assembly noise suppression in consumer electronics
• EMI filtering for data communication lines
• Signal integrity enhancement in industrial instrumentation cables

Procurement Notes

Verify current lifecycle status as sources indicate this model may be obsolete. Confirm exact dimensional tolerances against the official datasheet before integration. Ensure the selected substitute maintains identical magnetic properties if availability is restricted. Check for updated part numbers within the same FB series family.

Selection Notes

Select based on required cable diameter compatibility with the 2.64mm inner dimension. Evaluate impedance requirements against the Type 73 material characteristics at target frequencies. Consider physical space constraints relative to the 7.92mm length. Validate that the solid core structure meets environmental durability needs.

Part Context

This component belongs to the Bourns FB series of cable ferrites. These cores are engineered for suppressing electromagnetic interference on cables carrying digital or analog signals. The series offers various material types and dimensions to address different frequency ranges and cable sizes across electronic systems.

Replacement Considerations

Publicly confirmed substitutes include FB73-226-RC from the same manufacturer series. Verify dimensional equivalence and material type consistency when considering alternative vendors or updated part numbers.
