BA28B1251

Overview

The BA28B1251 is a round ferrite clamp-on core from the BX28B series, designed for cable bundle EMI suppression. It features an adhesive base for secure mounting and has an inner diameter of 19.1 mm (0.752 inches). The component measures 35.1 mm in external length, 41.7 mm in external width, and 22.2 mm in external height. It provides an impedance of 138 Ohms at 100 MHz.

Feature Summary

• Round ferrite core design for cylindrical cable bundles
• Integrated adhesive base for permanent installation
• Clamp-on mechanism for easy retrofitting without wire disconnection

Applications

• Suppression of electromagnetic interference on round cable bundles
• EMI filtering in electronic equipment chassis
• Signal integrity enhancement for data transmission lines

Procurement Notes

Verify the specific adhesive type compatibility with the target substrate material before final integration. Confirm that the 19.1 mm inner diameter accommodates the maximum outer diameter of the cable bundle including insulation. Ensure the operating temperature range aligns with the environmental conditions of the deployment site to maintain magnetic performance stability.

Selection Notes

Select this model when a round profile is required for existing cable geometries. The adhesive base eliminates the need for additional fasteners or straps, simplifying assembly. Compare impedance characteristics against other BX28B variants if higher attenuation frequencies are needed. Consider the physical dimensions to ensure adequate clearance within the enclosure layout.
