Overview
The Delevan 4211R-3 is a through-hole axial ferrite bead designed for EMI and noise suppression in electronic circuits. It provides an impedance of 120 ohms at 100 MHz. The component features a wound bead construction with one turn, suitable for filtering applications requiring specific attenuation characteristics.
Feature Summary
- Provides effective EMI and RFI suppression through wound bead technology
- Designed for through-hole axial mounting on printed circuit boards
- Offers stable impedance performance for noise filtering applications
Applications
- General purpose EMI/RFI noise suppression in electronic circuits
- Signal line filtering for noise reduction
- Power supply input/output filtering
Procurement Notes
Verify the exact impedance value and frequency rating against the official API Delevan datasheet before procurement. Confirm availability status as distribution channels may vary. Ensure the axial lead configuration matches the target PCB footprint requirements for proper installation.
Selection Notes
Select this component when a 120 ohm impedance at 100 MHz is required for noise suppression. Consider the axial package style for through-hole assembly processes. Evaluate current carrying capacity and DC resistance specifications from the manufacturer's documentation to ensure compatibility with the circuit design constraints.
Part Context
The 4211R-3 belongs to the API Delevan ferrite bead series, which includes various impedance values and package types. This specific model utilizes a wound bead design, distinguishing it from standard chip or surface mount ferrite beads. It serves as a passive filter component within the broader category of electromagnetic interference suppressors.
Replacement Considerations
Direct substitutes include other axial ferrite beads with similar 120 ohm impedance ratings. Verify mechanical dimensions and lead spacing to ensure physical compatibility. Cross-reference electrical parameters such as DC resistance and current handling capabilities with alternative components from the same manufacturer or other suppliers.
