SB28B2035AT

Overview

The SB28B2035AT is a hinged snap-on ferrite core manufactured by Leader Tech Inc. It features an internal diameter of 18.50mm (0.728 inches) and an outer dimension of 24.50mm width by 12.50mm height. The component provides an impedance of 65 Ohms at a test frequency of 100 MHz. It is designed for cable bundles up to 18.5mm in diameter, allowing single-location RFI suppression for multiple cables without saturation.

Feature Summary

• Hinged snap-on design enables easy installation around existing cable bundles
• Box-shaped assembly allows independent reaction of each circuit with suppression material
• Adhesive top mount style facilitates secure attachment to enclosures or surfaces

Applications

• Suppression for cable bundles up to 18.5mm diameter
• RFI mitigation in electronic enclosures
• EMI shielding for interconnect cables

Procurement Notes

Verify the specific adhesive mounting configuration required for your application, as this model includes an adhesive base. Confirm that the 18.50mm inner diameter accommodates your target cable bundle size. Ensure compatibility with the 65 Ohm impedance specification at 100 MHz for your EMI/RFI requirements. Check datasheet for precise dimensional tolerances.

Selection Notes

Select this part when a hinged ferrite core is needed for cables up to 18.5mm. The 65 Ohm impedance at 100 MHz suits general RFI suppression. The adhesive top mount simplifies installation compared to free-hanging variants. Consider if the box shape fits within your enclosure constraints.

Part Context

Leader Tech Inc. specializes in EMI shielding products for circuit boards, enclosures, and cables. This ferrite core belongs to their line of cable and wiring suppressors, designed to provide reliable board, enclosure, and cable solutions. The company is recognized as a leading innovator in US-manufactured shielding components.

Replacement Considerations

The SS28B2035 is a non-adhesive variant of the same core. For variable diameter end ports with flexible spring flutes, consider AS28B2044 or SS28B2044. Verify impedance and physical dimensions match before substituting.
