28J0138-11R-10

Overview

The Laird-Signal Integrity Products 28J0138-11R-10 is a discontinued axial ferrite bead designed for electromagnetic interference (EMI) filtering. It features a single-line configuration with an impedance of 143 Ohms at 100 MHz. The component supports a maximum rated current of 5A and maintains a low DC resistance of 10 milliohms. It utilizes a through-hole mounting style in an axial, open radial bent package. Physical dimensions include a diameter of 0.138 inches (3.51mm) and a maximum height of 0.183 inches (4.65mm).

Feature Summary

Provides high-frequency noise suppression with 143 Ohms impedance at 100 MHz.
Supports high-current applications up to 5A with minimal DC voltage drop.
Features axial leads for easy through-hole integration into circuit boards.

Applications

Power line EMI filtering in electronic equipment.
Signal line noise reduction in industrial systems.
Common mode noise suppression in axial leaded circuits.

Procurement Notes

This component is officially discontinued and no longer manufactured by Laird-Signal Integrity Products. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Engineers must confirm the functional equivalence of replacement parts before procurement to ensure compatibility with existing designs.

Selection Notes

Designers requiring this specific impedance and current rating should evaluate active alternatives within the Laird 28 series. The 28L0138-50R-10 is identified as a direct substitute offering similar electrical characteristics. Selection should prioritize components with verified RoHS compliance and matching physical footprint constraints for seamless retrofitting.

Part Context

The 28J0138-11R-10 belongs to the Laird 28 series of ferrite beads, which are widely used for broadband noise suppression. This series typically offers robust performance across various temperature ranges. As a legacy part, it represents earlier generations of axial ferrite technology before newer surface-mount or updated axial variants were introduced.
