742700790

Overview

The Würth Elektronik part number 742700790 is a WE-AFB EMI Suppression Axial Ferrite Bead designed for general electronic equipment. It features an axial leaded construction suitable for through-hole mounting applications. The component serves as a passive filter to attenuate high-frequency noise on single conductors.

Feature Summary

• Axial ferrite bead design for electromagnetic interference suppression
• Suitable for through-hole PCB mounting and wire wrapping
• Engineered for use in general electronic equipment environments

Applications

• General electronic equipment noise filtering
• Single conductor EMI suppression
• Through-hole circuit board integration

Procurement Notes

Verify the specific impedance value and current rating against the official Wurth Elektronik datasheet before procurement, as these parameters are critical for circuit performance. Confirm that the axial package style matches the target PCB layout requirements. Ensure compliance with relevant regional environmental directives such as RoHS if mandated by the end product specifications.

Selection Notes

Select this component when axial leads are required for mechanical stability or existing manufacturing processes. Consider the physical size constraints of the axial form factor compared to surface mount alternatives. Evaluate the frequency range of the noise source to ensure the ferrite material provides adequate attenuation at the target frequencies without saturating under normal operating currents.

Part Context

This part belongs to the WE-AFB series from Würth Elektronik, which focuses on axial ferrite beads for EMI suppression. The series offers various impedance values and current ratings to suit different signal lines. It complements the company's broader portfolio of ferrite cores and chokes used in power and data line protection.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching axial geometry, impedance characteristics, and current handling capabilities with other manufacturers' axial ferrite bead offerings.
