WBC3/ERT-4B1-Z

Overview

The WBC3/ERT-4B1-Z is a radial ferrite bead manufactured by Ferroxcube, designed for electromagnetic interference (EMI) suppression. It utilizes the proprietary 4B1 soft ferrite material, which provides high permeability and low loss characteristics suitable for broadband applications. The component features a through-hole mounting style with a maximum height of 10.50mm. This part is classified as an active EMI-suppression product intended for integration into circuits requiring noise attenuation across wide frequency ranges.

Feature Summary

• Radial leaded construction for through-hole PCB mounting
• Utilizes 4B1 soft ferrite material for broadband performance
• Designed for effective electromagnetic interference suppression

Applications

• Broadband chokes in electronic circuits
• General EMI suppression tasks
• Signal integrity protection in sensitive electronics

Procurement Notes

Verify the specific impedance value at the required operating frequency against official datasheets, as generic listings may not reflect precise electrical characteristics. Confirm that the 4B1 material grade aligns with thermal and magnetic requirements. Ensure the radial package dimensions fit the designated board layout. Cross-reference the manufacturer's current status to confirm active production availability before finalizing procurement plans.

Selection Notes

Select this component when broadband noise suppression is required without significant signal distortion. The 4B1 material offers a balance of permeability and resistivity ideal for general-purpose EMI filtering. Consider the physical size constraints due to the radial lead form factor. Evaluate the thermal environment to ensure the ferrite material operates within its specified temperature range during continuous duty cycles.

Part Context

This component belongs to the WBC series of ferrite beads from Ferroxcube, a global leader in magnetic components. The series includes various shapes and materials tailored for different frequency responses. The WBC designation indicates a specific bead geometry optimized for through-hole assembly. Ferroxcube’s heritage from Philips ensures consistent quality and reliability in soft ferrite manufacturing for industrial and consumer markets.

Replacement Considerations

Potential substitutes include other radial ferrite beads using similar 4B1-grade materials or equivalent high-permeability compositions. Verify mechanical footprint compatibility and lead spacing. Check impedance curves at target frequencies to ensure comparable attenuation performance. Alternative models such as those from the same WBC family with different suffixes may offer varied impedance levels.
