Overview
The Delevan 4211R-16 is an axial leaded ferrite bead filter component designed for EMI/RFI suppression. It belongs to the 4211R series of surface-mount and through-hole inductive devices. The unit features a wound bead construction with axial terminations suitable for standard PCB mounting. It provides specific impedance characteristics at high frequencies to attenuate noise signals.
Feature Summary
- Axial leaded construction for through-hole integration
- Wound ferrite bead design for signal filtering
- EMI and RFI suppression capabilities
Applications
- High-frequency noise attenuation in electronic circuits
- Signal line filtering for EMI compliance
- RFI suppression in communication equipment
Procurement Notes
Verify the exact impedance value and tolerance against the official API Delevan datasheet before procurement, as suffixes define electrical parameters. Confirm RoHS status and packaging type directly with the manufacturer or authorized distributors. Ensure the axial lead configuration matches the target PCB footprint requirements.
Selection Notes
Select this component when axial termination is required for mechanical stability or existing board layouts. Compare impedance specifications at the target operating frequency against alternative series like 4212R if radial options are viable. Validate thermal and current handling limits against circuit conditions to ensure reliable operation without saturation.
Part Context
This part is part of the API Delevan 4211R series, which includes various ferrite beads with different impedance ratings. The series offers both surface-mount and through-hole options. Delevan manufactures these components for high-reliability applications requiring effective electromagnetic interference suppression in compact form factors.
Replacement Considerations
Check equivalent parts within the 4211R series for matching impedance values. Verify that any substitute maintains the same axial lead spacing and overall dimensions to fit the existing assembly.
