Overview
The Delevan 4211R-5 is an axial leaded ferrite bead designed for EMI/RFI suppression. It exhibits an impedance of 109 Ohms at a test frequency of 100 MHz. The component features a single turn winding configuration and measures 3.5 mm in diameter with a length of approximately 6.0 mm. Packaged in tape and reel format, it supports automated surface mount or through-hole processing depending on the specific application requirements.
Feature Summary
- Provides effective electromagnetic interference and radio frequency interference suppression
- Features axial leaded construction for secure circuit board mounting
- Utilizes wound bead technology for stable high-frequency performance
Applications
- High-speed digital signal line filtering
- Power supply input/output noise reduction
- Communication interface protection circuits
Procurement Notes
Verify the exact impedance tolerance and physical dimensions against the official API Delevan datasheet before integration. Confirm that the axial lead style matches the target PCB footprint design. Ensure the supplier provides valid RoHS compliance documentation as required by project specifications.
Selection Notes
Select this component when a specific 109 Ohm impedance at 100 MHz is required for noise attenuation. Consider the axial package constraints relative to available board space. Evaluate the current carrying capacity against the operational load to prevent saturation or excessive heating during continuous use.
Part Context
This part belongs to the 4211R series of ferrite beads manufactured by API Delevan. The series offers various impedance values and winding configurations tailored for different frequency suppression needs. The 4211R-5 specifically targets applications requiring moderate impedance characteristics for general-purpose EMI control.
Replacement Considerations
Direct substitutes include other 109 Ohm axial ferrite beads from compatible manufacturers. Verify equivalent impedance curves and physical envelope dimensions to ensure mechanical compatibility without redesigning the PCB layout.
