Overview
The Delevan 4211R-11 is an axial leaded ferrite bead designed for EMI/RFI suppression. It exhibits a nominal impedance of 469 Ohms at a test frequency of 100 MHz. The component utilizes a wound bead construction with one turn, housed in an axial package suitable for through-hole mounting. This filter bead serves as a passive magnetic component to attenuate high-frequency noise in electronic circuits.
Feature Summary
- Provides effective attenuation of electromagnetic interference and radio frequency interference signals
- Utilizes a wound bead design for stable high-frequency performance
- Features axial leads for reliable through-hole integration into printed circuit boards
Applications
- High-frequency signal line filtering
- Power supply noise suppression
- Data bus protection against EMI/RFI disturbances
Procurement Notes
Verify the specific impedance tolerance and current rating requirements against the official API Delevan datasheet before ordering. Confirm that the axial lead configuration matches the target PCB footprint. Ensure compatibility with the intended operating temperature range and frequency spectrum for the specific application environment.
Selection Notes
Select this component when a discrete axial ferrite bead is required for targeted noise reduction at 100 MHz. Consider the physical dimensions and lead spacing to ensure proper mechanical fit within the assembly constraints. Evaluate the impedance characteristics relative to the source and load impedances to maximize insertion loss effectiveness.
Part Context
This part belongs to the API Delevan family of passive magnetic components, specifically the ferrite bead series. Delevan manufactures these devices to meet stringent reliability standards for government and commercial applications. The product line focuses on providing high-performance inductive solutions for various electrical filtering requirements across multiple industries.
Replacement Considerations
Consult the manufacturer's cross-reference documentation for verified substitutes. Ensure any replacement maintains identical axial packaging, impedance values at 100 MHz, and current handling capabilities to preserve circuit integrity.
