4211R-26

Overview

The Delevan 4211R-26 is an axial lead ferrite bead designed for EMI/RFI suppression. It exhibits an impedance of 93 Ohms at a frequency of 25 MHz. The component features a radial or axial configuration with standard through-hole mounting capabilities. Physical dimensions include a diameter of 3.5 mm and a length of 6 mm. It is classified as a single-line filter suitable for high-reliability applications requiring effective noise attenuation in electronic circuits.

Feature Summary

• Provides effective EMI and RFI suppression across specified frequency ranges
• Features axial lead construction for reliable through-hole integration
• Designed for high-reliability performance in stringent environments

Applications

• Electronic circuit noise filtering
• Signal line interference suppression
• Power supply output smoothing

Procurement Notes

Verify the specific impedance value and physical dimensions against the official manufacturer datasheet before integration. Confirm RoHS compliance status and lead material specifications to ensure alignment with environmental regulations and assembly processes. Cross-reference the part number with authorized distributors to validate authenticity and current manufacturing status.

Selection Notes

Select this component when axial ferrite beads are required for low-frequency noise suppression around 25 MHz. Ensure the PCB layout accommodates the 6 mm length and 3.5 mm diameter. Consider thermal dissipation requirements and current carrying capacity if used in power paths, although primary function is signal integrity enhancement.

Part Context

This part belongs to the Delevan 4211R series of ferrite beads. The series offers various impedance values tailored for different frequency suppression needs. Delevan specializes in passive magnetic components, focusing on high-quality inductors and filters for government and industrial specifications.

Replacement Considerations

Check for direct substitutes within the 4211R series offering similar impedance at 25 MHz. Verify that alternative parts match the axial package dimensions and mounting style to maintain mechanical compatibility without redesigning the footprint.
