SB28B4340

Overview

The SB28B4340 is a hinged ferrite core manufactured by Leader Tech Inc., designed for EMI suppression on cables. It features a circular shape with a snap-on installation type and free-hanging mounting style. The component utilizes Material 28, providing an impedance of 150 Ohms at 100MHz. Key dimensions include an inner diameter of 3.240 inches (82.30mm), an outer dimension of 4.339 inches wide by 0.252 inches high (110.20mm x 6.40mm), and a length of 1.126 inches (28.60mm).

Feature Summary

• Hinged snap-on design allows for easy installation around existing cables without disconnection.
• Constructed from Material 28 ferrite composition to provide effective electromagnetic interference suppression.
• Free-hanging configuration enables versatile placement in various cable management scenarios.

Applications

• Suppression of electromagnetic interference on large diameter power or signal cables.
• EMI filtering in industrial equipment and machinery cabling systems.
• Noise reduction in telecommunications infrastructure requiring large cable diameters.

Procurement Notes

Verify the specific impedance value and physical dimensions against your cable diameter requirements before ordering. Confirm that the hinged design accommodates the cable assembly process in your application. Check for RoHS3 compliance status if required by your manufacturing standards. Ensure the manufacturer part number matches exactly to avoid compatibility issues with existing inventory.

Selection Notes

Select this component when dealing with cables having an inner diameter up to 3.240 inches. The 150 Ohm impedance at 100MHz suits general EMI noise reduction needs. Consider the free-hanging nature for applications where fixed mounting points are unavailable. Compare material properties if higher frequency performance is critical for your specific noise profile.
