B-5

Overview

The KEMET B-5 is a ferrite bead component designed for EMI and RFI suppression applications. It features a toroid construction with a current rating of 1.5 A. The device belongs to the BEAD W series, intended for noise filtering in electronic circuits. As a passive component, it operates within standard environmental conditions compliant with RoHS directives.

Feature Summary

• Toroidal geometry for effective magnetic flux containment
• Designed for electromagnetic interference suppression
• Rated for continuous current handling up to 1.5 A

Applications

• EMI/RFI noise filtering in power lines
• Signal line protection against high-frequency interference
• General-purpose electromagnetic compatibility enhancement

Procurement Notes

Verify that the specific order matches the BEAD W series designation and the 1.5 A current rating. Confirm RoHS compliance status if required by project specifications. Ensure the toroidal form factor fits the mechanical constraints of the target assembly. Cross-reference the manufacturer's official documentation for precise impedance characteristics at relevant frequencies.

Selection Notes

Select this component when a through-hole or leaded toroidal ferrite solution is required for moderate current levels. The 1.5 A rating suits applications where higher current beads are unnecessary. Consider the physical size of the toroid relative to available board space. Evaluate the frequency range of the noise to ensure the ferrite material provides adequate attenuation.

Part Context

This part falls under KEMET’s broader portfolio of passive components, specifically within the ferrite and inductor categories. It complements other EMI suppression products by offering a simple, robust solution for common-mode or differential-mode noise reduction. The brand is recognized for reliable passive electronic materials.
