B-13

Overview

The KEMET B-13 is a ferrite bead component designed for electromagnetic interference suppression in DC line filter applications. It operates with a normal mode configuration and features a winding structure with a 0.4 mm bead diameter. The device is rated to handle a current of 2.5 A, providing impedance characteristics suitable for noise attenuation in power supply lines without introducing significant resistive voltage drop under nominal load conditions.

Feature Summary

• Designed for normal mode noise suppression in DC line filters
• Utilizes a wound bead construction with a 0.4 mm diameter
• Rated for continuous current handling up to 2.5 A

Applications

• DC line filtering
• Electromagnetic interference suppression
• Power supply noise attenuation

Procurement Notes

Verify the specific impedance curve and frequency response against the official KEMET datasheet to ensure compatibility with target noise frequencies. Confirm that the 2.5 A current rating aligns with the maximum operating current of the application circuit to prevent saturation or thermal issues during procurement validation.

Selection Notes

Select this component when normal mode filtering is required for DC lines carrying currents up to 2.5 A. Ensure the physical dimensions of the wound bead fit within the available PCB or chassis space. Validate that the impedance profile at the target noise frequencies meets the system's EMI reduction requirements compared to alternative core materials.

Part Context

The B-13 belongs to KEMET's range of passive components focused on signal integrity and power line conditioning. Ferrite beads in this category are distinct from resistors as they provide frequency-dependent impedance, primarily dissipating high-frequency noise energy as heat while maintaining low resistance for DC signals.
