74270054

Overview

The Würth Elektronik part number 74270054 is an EMI suppression axial ferrite bead belonging to the WE-AFB series. It is constructed from NiZn material and designed for common mode noise reduction in single or double wire configurations. The component exhibits an impedance of 94 Ohms at 100 MHz for a single wire and 92 Ohms for a double wire setup. It operates within a temperature range of -40°C to +90°C and features a round shape with internal dimensions of 1.8 mm.

Feature Summary

• Provides effective common mode noise suppression for signal and power lines
• Utilizes NiZn ferrite material for high-frequency attenuation
• Supports installation on both single and double wire configurations

Applications

• Common mode noise suppression in electronic circuits
• Signal line filtering for data transmission
• Power line interference mitigation

Procurement Notes

Verify the exact manufacturer part number against official Wurth Elektronik documentation before procurement. Confirm that the specific application requires the WE-AFB axial form factor and the stated impedance characteristics at 100 MHz. Ensure compliance with RoHS standards if required by the target assembly process.

Selection Notes

Select this component when axial ferrite beads are required for compact EMI suppression. The choice depends on the need for NiZn material properties and the specific impedance profile at 100 MHz. Consider the physical size constraints and the operating temperature range of -40°C to +90°C during the design phase.

Part Context

This component is part of the WE-AFB series, which focuses on axial ferrite beads for EMI suppression. It serves as a passive filter element to attenuate high-frequency noise. The series is distinct from snap-on cores and offers a through-hole mounting solution for printed circuit boards or cable assemblies.
