Overview
The Delevan 4211R-9 is an axial leaded ferrite bead designed for EMI/RFI suppression in electronic circuits. It operates as a passive noise filter with a characteristic impedance of 325 Ohms at 100 MHz. The component features a single ferrite bead element housed in an axial configuration, suitable for through-hole mounting. Its physical dimensions are 0.385 inches in diameter by 0.450 inches in length (9.78 mm x 11.43 mm). This part belongs to the 4211(R) series of ferrite beads and chips.
Feature Summary
- Provides electromagnetic interference and radio frequency interference suppression
- Features a single ferrite bead element in an axial leaded package
- Designed for through-hole mounting on printed circuit boards
Applications
- EMI/RFI filtering in signal lines
- Noise suppression in power supply circuits
- High-frequency signal integrity improvement
Procurement Notes
Verify the specific suffix 'R-9' corresponds to the 325 Ohm impedance variant when sourcing. Confirm axial leaded construction matches the target PCB footprint. Check RoHS compliance status as documentation may vary by production batch. Ensure the supplier provides official API Delevan or authorized distribution channels to guarantee component authenticity and traceability.
Selection Notes
Select this component when axial through-hole mounting is required for EMI suppression. The 325 Ohm impedance value suits high-frequency noise attenuation applications. Consider the physical size constraints of the assembly area. Verify that the current rating meets the circuit requirements, although specific current data is not provided in the available public documentation for this exact part number.
Part Context
The 4211R-9 is part of the broader 4211 series of ferrite beads manufactured by API Delevan. This series includes various impedance values and configurations, such as surface mount and different axial variants. The R-9 designation specifically identifies the 325 Ohm impedance version within this product line, distinguishing it from other members like the 4211-9 or 4211R-1 which have different specifications.
Replacement Considerations
Publicly confirmed substitute part numbers for the 4211R-9 are not available in the provided source material. Engineers should consult manufacturer cross-reference tools or datasheets for equivalent axial ferrite beads with matching 325 Ohm impedance and similar physical dimensions.
