742700752

Overview

The Wurth Elektronik part number 742700752 is an EMI suppression axial ferrite bead belonging to the WE-AFB series. It features a cylindrical solid core constructed from 3W800 material, providing an impedance of 113 Ω at 100 MHz. The component has an inner diameter of 8 mm, an outer diameter of 16 mm, and an external length of 16 mm. It operates within a temperature range of -25 °C to +85 °C and complies with RoHS and REACH standards.

Feature Summary

• Provides electromagnetic interference suppression for power supplies, data lines, and gauge signal cables
• Utilizes 3W800 material composition for consistent high-frequency attenuation characteristics
• Designed as a solid round cable core for straightforward installation on existing wiring

Applications

• Power supply cable assembly
• Computer data line protection
• Gauge signal line filtering

Procurement Notes

Verify the specific impedance value against the latest manufacturer datasheet, as online listings may vary between 113 Ω and 505 Ω. Confirm that the 8 mm inner diameter matches the target cable bundle size. Ensure compliance requirements such as RoHS are explicitly stated in the final purchase order documentation.

Selection Notes

Select this component when a solid cylindrical ferrite core is required for retrofitting existing cables without disassembly. The 8 mm aperture accommodates moderate cable diameters. Consider the 113 Ω impedance rating at 100 MHz for typical EMI noise frequencies. Evaluate thermal limits if the application involves sustained high currents or elevated ambient temperatures.

Part Context

This component belongs to the WE-AFB series of axial ferrite beads manufactured by Würth Elektronik. These parts are designed specifically for suppressing common mode noise on cables. The series offers various impedance ratings and dimensions to suit different cable sizes and frequency requirements.
