4211R-24

Overview

The Delevan 4211R-24 is an axial leaded ferrite bead designed for EMI and RFI suppression. It exhibits a nominal impedance of 103 Ohms at a test frequency of 25 MHz. The component features a single-turn wound construction on a ferrite core, housed in a compact axial package with dimensions of approximately 3.5 mm in diameter and 0.175 inches in length. It is RoHS compliant and suitable for surface mount or through-hole integration depending on the specific circuit board design requirements.

Feature Summary

• Provides effective electromagnetic interference and radio frequency interference suppression
• Features a robust axial leaded termination style for secure mounting
• Utilizes a ferrite core material optimized for high-frequency noise attenuation

Applications

• General purpose EMI/RFI filtering in electronic circuits
• Signal line noise suppression in communication equipment
• Power supply input/output filtering applications

Procurement Notes

Verify the exact impedance tolerance and current rating specifications against the official manufacturer datasheet before finalizing procurement. Confirm that the axial lead configuration matches your PCB footprint requirements. Ensure compliance with relevant environmental regulations such as RoHS if applicable to your manufacturing process. Cross-reference the part number with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component when a low-profile axial ferrite bead is required for high-frequency noise reduction. The 103 Ohm impedance value at 25 MHz makes it suitable for suppressing noise in specific frequency bands. Consider the physical dimensions and lead spacing to ensure compatibility with your assembly process. Evaluate the thermal and electrical characteristics to ensure they meet the operational demands of your specific application environment.

Part Context

This component belongs to the Delevan 4211R series of ferrite beads on leads. This series is characterized by its axial leaded format and ferrite core construction, distinguishing it from surface-mount chip beads or air-core inductors within the broader Delevan portfolio. The 4211R series is engineered for reliable performance in demanding electronic environments requiring effective passive filtering solutions.

Replacement Considerations

Direct substitutes may include other axial ferrite beads with similar impedance values at comparable frequencies. Verify mechanical dimensions and lead spacing to ensure fitment. Check electrical parameters such as DC resistance and saturation current to maintain circuit performance integrity during replacement.
