AS28B2035-15

Overview

The AS28B2035-15 is a hinged ferrite clamp-on suppressor manufactured by Leader Tech Inc. It features a square box-shaped design with an internal diameter of 1.00 mm (0.039 inches). The component provides an impedance of 270 Ohms at a test frequency of 100 MHz. Its external dimensions are 31.80 mm in width and 1.157 inches in height. This unshielded device utilizes axial termination and is constructed from Ferrite material type 28, designed for cable bundle suppression.

Feature Summary

• Hinged snap-on design allows for easy installation around existing cables without disconnection
• Box-shaped ferrite assembly enables single-location RFI suppression for multiple cables within a bundle
• Independent circuit reaction prevents saturation when suppressing noise across multiple conductors

Applications

• Suppression of electromagnetic interference in small-diameter cable bundles
• RFI mitigation for individual wires or grouped cables in electronic enclosures
• Noise reduction in data and signal transmission lines requiring compact form factors

Procurement Notes

Verify the specific suffix designation to confirm the exact internal diameter and impedance rating, as variations exist within the AS28B20 series. Ensure compatibility with the target cable bundle size, noting that this specific model has a 1.00 mm ID. Confirm RoHS compliance status through the manufacturer's current documentation before integration into regulated assemblies.

Selection Notes

Select this component when space constraints require a low-profile, hinged ferrite core for small cables. The 270 Ohm impedance at 100 MHz makes it suitable for high-frequency noise suppression. Consider the adhesive base variant if permanent mounting is required, or the standard snap version for serviceable connections. Evaluate the maximum cable diameter against the 1.00 mm internal opening to ensure proper fit.

Part Context

This part belongs to the LeaderTech EMI/RFI suppressor family, specifically the clamp-on ferrite cores category. These components are engineered for board, enclosure, and cable solutions. The AS28B2035-15 represents a specialized size within the broader SS28B20xx series, distinguished by its specific hinge mechanism and dimensional profile for precise cable management applications.

Replacement Considerations

Direct substitutes include other hinged ferrite clamps with similar 1.00 mm ID and comparable impedance characteristics. Verify mechanical fitment and magnetic material properties when cross-referencing with generic ferrite cores. Alternative LeaderTech models may offer different impedances or larger diameters depending on specific noise frequency requirements.
