28B1540-000

Overview

The Laird-Signal Integrity Products 28B1540-000 is a solid, free-hanging ferrite core designed for cable noise suppression. It features a cylindrical geometry with an inner diameter of 0.660 inches (16.76mm), an outer diameter of 1.540 inches (39.12mm), and a length of 0.875 inches (22.22mm). The component utilizes Material 28 technology to provide an impedance of 254 Ohms at 100MHz. It is classified as a cable ferrite suitable for high-current applications requiring robust electromagnetic interference mitigation.

Feature Summary

• Solid construction provides consistent magnetic properties without air gaps
• Material 28 formulation optimized for broadband noise attenuation
• Free-hanging mounting allows installation on existing cables without disconnection

Applications

• Suppression of common-mode noise on power cables
• Electromagnetic interference filtering for signal lines
• Cable assembly noise reduction in industrial equipment

Procurement Notes

Verify the specific impedance tolerance and material batch consistency against the manufacturer's datasheet before integration. Confirm that the inner diameter accommodates the target cable bundle diameter with appropriate clearance. Ensure compliance with RoHS3 and REACH regulations required by your supply chain standards.

Selection Notes

Select this component when high current capacity and broad frequency attenuation are required. The large physical dimensions support higher saturation levels compared to smaller cores. Evaluate the thermal environment to ensure stable performance under operating conditions.

Part Context

This part belongs to the 28B series of cable ferrites from Laird-Signal Integrity Products. It complements other solid core variants like the 28B0157-100 but offers significantly larger dimensions and higher impedance characteristics suited for heavier gauge cabling and more demanding noise profiles.
