SB28B0937

Overview

The SB28B0937 is a hinged ferrite core manufactured by Leader Tech Inc., designed for electromagnetic interference (EMI) suppression. It utilizes material grade 28 and provides an impedance of 34 ohms at 100 MHz. The component features a hinged design with nylon strap bonding, allowing it to function with wires and cables up to a diameter of 1.00 inch (25.4 mm). Physical dimensions include a length of 23.8 mm and a thickness of 11.9 mm. Holes are provided for mounting purposes.

Feature Summary

• Hinged ferrite assembly bonded to a nylon strap for secure cable retention
• Compatible with wires and cables up to a 1.00 inch diameter
• Includes mounting holes for installation flexibility

Applications

• Suppression on wires and cables up to 1.00 inch diameter
• Electromagnetic interference filtering in electronic assemblies
• Cable management and shielding in industrial equipment

Procurement Notes

Verify the specific impedance value against official datasheets, as conflicting public data exists regarding whether the unit is 34 ohms or 117 ohms at 100 MHz. Confirm the exact physical dimensions and material grade (28) match project requirements. Ensure the hinged nylon strap design aligns with the intended cable diameter and mounting constraints before finalizing procurement.

Selection Notes

Select this component when a reusable, hinged ferrite solution is required for cables up to 1.00 inch in diameter. The nylon strap bonding offers a secure alternative to snap-on cores for larger cables. Verify that the mounting holes accommodate the specific mechanical fastening needs of the application environment.

Part Context

This part belongs to the SB28 series of EMI gaskets, sheets, and absorbers from Leader Tech Inc. The series focuses on ferrite-based solutions for noise suppression. The SB28B0937 specifically addresses applications requiring hinged access and compatibility with substantial cable bundles, distinguishing it from simple bead or clamp designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing harnesses if direct replacement is necessary.
