• Wide-band choke applications requiring high impedance
• Power supply input/output filtering

Common Mode Chokes Procurement Notes

This component is scheduled for obsolescence and will be discontinued by the manufacturer. Verify availability status carefully before procurement planning. Sourcing may be limited to existing stock or secondary distributors. Confirm end-of-life timelines with suppliers to ensure project continuity and avoid future supply chain disruptions.

Common Mode Chokes Selection Notes

Select this component for applications requiring a 430 Ohm impedance at 100 MHz and a 5 A current rating. Ensure the design accommodates through-hole axial mounting constraints. Consider the discontinuation status when evaluating long-term production viability and potential need for redesign.

Common Mode Chokes Part Context

The FB20011-3B-RC belongs to Bourns' wide-band choke series, specifically engineered for common mode noise reduction. It is part of the FB20011 family, characterized by its ferrite core construction and axial leaded package. This series targets robust EMI suppression in power and signal lines.

Common Mode Chokes Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the component's scheduled obsolescence. Evaluate alternative wide-band chokes with matching impedance (430 Ohms @ 100 MHz) and current rating (5 A) from other manufacturers.
