4211R-8

Overview

The Delevan 4211R-8 is an axial leaded ferrite bead designed for EMI/RFI suppression in electronic circuits. It exhibits a nominal impedance of 264 Ohms at a test frequency of 100 MHz. The component features a single-turn wound construction, providing effective noise attenuation across high-frequency bands. Its physical dimensions are approximately 3.5 mm in diameter and 13.8 mm in length, allowing for integration into compact assemblies. The device operates within a standard temperature range suitable for general industrial applications.

Feature Summary

• Provides electromagnetic interference suppression through high-frequency impedance characteristics
• Features axial leaded termination for through-hole PCB mounting
• Utilizes a single-turn wound ferrite core design for signal integrity

Applications

• General EMI/RFI filtering in electronic circuitry
• Noise suppression on power and signal lines
• Compact space-constrained electronic assemblies

Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets may be managed by other entities. Confirm RoHS compliance status directly with the supplier or current datasheet, as legacy components may have varying environmental declarations. Ensure the axial lead configuration matches the target PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when axial mounting is required for ferrite bead applications. The 264 Ohm impedance value targets specific noise frequencies around 100 MHz. Consider the physical size constraints relative to the available board space. Verify that the single-turn design meets the necessary inductance and impedance profiles for the intended circuit topology.
