4212R-3

Overview

The Delevan 4212R-3 is a ferrite wound bead EMI/RFI suppressor designed for through-hole axial mounting. It provides an impedance of 425 Ohms at a test frequency of 100 MHz. The component features a single-line configuration with a wound bead structure consisting of 1.5 turns. Physical dimensions include a length of 10.5 mm and a diameter of 6.35 mm. It is available in reel packaging and complies with RoHS3 standards.

Feature Summary

• Axial leaded construction for through-hole PCB integration
• Wound bead design providing high-frequency noise suppression
• Single-line topology for signal path filtering

Applications

• EMI/RFI suppression in electronic circuits
• High-frequency noise filtering on signal lines
• Through-hole assembly in industrial electronics

Procurement Notes

Verify the specific suffix (e.g., TR, BULK) to confirm packaging type, as availability varies between reels and bulk quantities. Confirm RoHS3 compliance status directly with the manufacturer or authorized distributor documentation before finalizing procurement specifications.

Selection Notes

Select this component when axial mounting is required for ferrite bead applications. Ensure the circuit layout accommodates the 10.5 mm length and 6.35 mm diameter. Verify that the 425 Ohm impedance at 100 MHz aligns with the target noise frequency spectrum for effective suppression.

Part Context

This part belongs to the 4212R series of ferrite wound beads manufactured by Delevan. The series offers various impedance values and termination styles, including radial options like the 4212R-8. The 4212R-3 specifically utilizes an axial termination style distinct from surface mount alternatives in the broader product line.

Replacement Considerations
