AS28B2037

Overview

The AS28B2037 is a hinged ferrite core manufactured by Leader Tech Inc., designed for cable electromagnetic interference suppression. It utilizes Material 28, providing an impedance of 200 Ohms at 100 MHz. The component features a circular shape with a hinged snap-fit design for easy installation around cables without disconnection. Key dimensions include an inner diameter of 8.80 mm (0.346 inches), an outer width and height of 20.1 mm (0.791 inches), and an external length of 36.8 mm (1.449 inches).

Feature Summary

• Hinged snap-fit design allows secure closure around cables without disconnecting wires.
• Material 28 composition provides high impedance characteristics for effective EMI suppression.
• Circular cross-section accommodates round cable bundles efficiently.

Applications

• Suppression of electromagnetic interference on single round cables.
• Noise filtering in electronic equipment wiring harnesses.
• Cable bundle protection in industrial control systems.

Procurement Notes

Verify the specific impedance value and physical dimensions against the official Leader Tech datasheet before integration. Confirm that the Material 28 specification aligns with the target frequency range requirements. Ensure the hinged mechanism integrity is suitable for the intended mechanical environment. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a non-invasive installation method is required for round cables. The 8.80 mm inner diameter must match the cable bundle size to ensure proper fit. Consider the 200 Ohm impedance at 100 MHz for compatibility with the noise spectrum being suppressed. The hinged design offers maintenance advantages over split-core or solid bead alternatives.

Part Context

This part belongs to the Leader Tech ferrite clamp-on core family, specifically utilizing Material 28 for general-purpose EMI suppression. It is categorized under passive components for electromagnetic interference filtering. The product line includes various shapes and mounting styles, with this model focusing on hinged circular designs for versatile cable management applications.

Replacement Considerations

SS28B2034K is listed as a parameter-equivalent substitute by the manufacturer. Verify dimensional compatibility and impedance curves before substitution.
