74270063

Overview

The Wurth Elektronik 74270063 is an EMI suppression axial ferrite bead from the WE-AFB series. It features a cylindrical design with an inner diameter of 7.92 mm and an outer diameter of 12.7 mm. The component has a length of 12.7 mm and utilizes 4W620 material. Electrical characteristics include an impedance of 50 Ω at 25 MHz and 90 Ω at 100 MHz for one turn, increasing to 70 Ω at 25 MHz and 130 Ω at 100 MHz for two turns.

Feature Summary

• Provides effective high-frequency noise suppression for signal and power lines
• Designed for easy installation on wires and coaxial cables without soldering
• Constructed from 4W620 ferrite material for stable performance

Applications

• Suppression of electromagnetic interference in wire harnesses
• Noise filtering for coaxial cables
• EMI reduction in wire-wrapping applications

Procurement Notes

Verify the specific impedance values required for your circuit against the datasheet specifications for one and two-turn configurations. Confirm that the cable diameter fits within the 7.92 mm inner diameter constraint. Ensure compliance with REACH and RoHS standards if applicable to your manufacturing region. Check for any specific packaging or handling requirements defined by the manufacturer.

Selection Notes

Select this component when axial ferrite beads are preferred over snap-on cores for permanent installations. Consider the impedance profile at operating frequencies to ensure adequate attenuation. Evaluate the physical dimensions to ensure compatibility with the available space in the assembly. Compare the 4W620 material properties against other materials if specific frequency responses are critical.

Part Context

This part belongs to the WE-AFB series of axial ferrite beads manufactured by Wurth Elektronik. These components are distinct from snap-on ferrite cores due to their fixed axial geometry. The series is designed for applications requiring robust EMI suppression directly on cables. The 74270063 model specifically targets mid-range cable diameters with defined impedance characteristics.
