FB73-085-RC

Overview

The FB73-085-RC is a solid free-hanging ferrite core manufactured by Bourns Inc., designed for EMI suppression. It features a sleeve type construction with material composition designated as 73, optimized for operation at a frequency of 40MHz. The component has an inner diameter of 0.78mm (0.031 inch) and an outer diameter of 1.42mm (0.056 inch), with a length of 2.41mm (0.095 inch). It supports a maximum operating temperature of 105°C and utilizes SMD/SMT termination methods.

Feature Summary

• Provides excellent EMI suppression capability at high frequencies
• Utilizes 73 material composition for specific magnetic properties
• Designed as a solid free-hanging sleeve core

Applications

• High-frequency EMI noise reduction in electronic circuits
• Signal integrity enhancement in compact electronic assemblies

Procurement Notes

Verify the obsolete status of this component before procurement, as it is not recommended for new designs. Confirm that the 73 material grade and 40MHz operating frequency align with current project requirements. Ensure compatibility with existing PCB layouts due to the specific physical dimensions and SMD/SMT termination style. Check for available alternative components from the manufacturer's current portfolio.

Selection Notes

Select this component only if the design allows for obsolete parts or requires legacy compatibility. The 73 material is suitable for specific frequency ranges around 40MHz. Consider the small physical footprint when designing for dense PCB layouts. Verify thermal stability up to 105°C against operational conditions. Evaluate replacement options if new production is planned.
