AS28B2042

Overview

The AS28B2042 is a hinged ferrite clamp-on core manufactured by Leader Tech Inc. It utilizes Material 28 to provide high impedance for EMI suppression. The component features a square cross-section with an internal diameter of 10.8 mm (0.425 inches). External dimensions are 37.6 mm in length, 24.5 mm in width, and 23.6 mm in height. It offers an impedance of 238 Ohms at 100 MHz.

Feature Summary

• Hinged snap-spring design allows for easy installation onto existing cables without disconnection.
• Material 28 composition provides high magnetic permeability for effective noise attenuation.
• Square profile accommodates flat or bundled cable configurations securely.

Applications

• Suppression of electromagnetic interference on single power or signal cables
• Noise reduction in computer peripheral connections
• EMI filtering on industrial control wiring harnesses

Procurement Notes

Verify the specific impedance value and material grade against the official datasheet before procurement. Confirm that the internal diameter matches the target cable bundle size. Check RoHS compliance status if required by project specifications. Ensure the hinged mechanism is intact upon receipt to guarantee secure closure during operation.

Selection Notes

Select this part when a non-invasive solution is required for cables with diameters up to 10.8 mm. The Material 28 formulation is suitable for frequencies where higher permeability is needed compared to standard mix materials. Consider the external dimensions to ensure adequate clearance within the enclosure or chassis layout.

Part Context

This component belongs to the AS28 series of hinged ferrite cores from Leader Tech. These parts are designed for rapid deployment on cables to mitigate common-mode noise. The series typically includes various internal diameters and lengths to suit different cable sizes while maintaining consistent electrical performance characteristics defined by the ferrite material mix.

Replacement Considerations

SS28B2042K is listed as a parameter equivalent substitute. Verify dimensional compatibility and impedance tolerance before substitution.
