AS28B2043

Overview

The AS28B2043 is a hinged ferrite clamp-on suppressor manufactured by Leader Tech Inc. It features a box-shaped sleeve design with an internal diameter of 18.50 mm, suitable for cable bundles up to that width. The component provides an impedance of 260 Ohms at a test frequency of 100 MHz. It utilizes Type 28 ferrite material and includes an adhesive base for secure mounting.

Feature Summary

• Hinged box sleeve design allows for easy installation around existing cable bundles without disconnection.
• Adhesive base provides a fixed mounting solution for single-location RFI suppression on multiple cables.
• Type 28 ferrite material offers high impedance characteristics for effective noise attenuation.

Applications

• Suppression of electromagnetic interference in multi-cable bundles
• RFI mitigation in electronic enclosures and board-level assemblies
• Noise reduction for data and power transmission lines

Procurement Notes

Verify the specific ordering suffix to confirm the presence of the adhesive base, as non-adhesive variants such as SS28B2043 exist within the same series. Ensure the target cable bundle diameter does not exceed the specified 18.50 mm internal dimension to guarantee proper fit and mechanical retention during operation.

Selection Notes

Select this component when a permanent, non-removable suppression solution is required for cable bundles. The hinged mechanism facilitates assembly on pre-routed wiring. Compare against standard snap-on cores if temporary access or reconfiguration of the cable harness is anticipated, as the adhesive mount limits post-installation removal.

Part Context

This part belongs to the xS28B series of ferrite clamp-on cores from Leader Tech Inc., designed for EMI/RFI suppression. The series encompasses various shapes and mounting options, including snap-on, button base, and adhesive base configurations, catering to diverse shielding requirements in electronic systems.

Replacement Considerations

SS28B2043 serves as a direct substitute if the adhesive base is not required, offering identical electrical and dimensional specifications without the mounting pad. Verify that the application environment supports the removal of the adhesive component if switching to the non-adhesive variant.

FAQ
