SB28B1729AT

Overview

The SB28B1729AT is a hinged ferrite clamp-on core manufactured by Leader Tech Inc. It features an adhesive bottom mounting style and belongs to the SB28 series. The component has an internal diameter of 19.10 mm and external dimensions of 38.10 mm in length, 35.50 mm in width, and 17.80 mm in height. It provides an impedance of 125 Ohms at 100 MHz and utilizes material grade 28 for EMI suppression.

Feature Summary

• Hinged design allows installation around existing cables without disconnection
• Adhesive bottom enables secure attachment to chassis or equipment surfaces
• Solid flat construction supports high-frequency noise attenuation

Applications

• EMI suppression on ribbon cables
• Chassis-mounted cable filtering
• Flat cable noise reduction

Procurement Notes

Verify the exact suffix (AT) against the manufacturer datasheet to confirm adhesive specifications and material grade. Ensure the internal diameter matches the target cable bundle size. Confirm RoHS compliance status with the supplier prior to ordering.

Selection Notes

Select this part when a hinged ferrite core with integrated adhesive backing is required for flat cable applications. The 125 Ohm impedance at 100 MHz suits general EMI suppression needs. Verify that the 19.10 mm internal diameter accommodates the specific cable geometry.

Part Context

This component is part of the Leader Tech SB28 series of ferrite cores. The series includes various sizes and configurations for EMI/RFI suppression. The SB28B1729AT specifically denotes a hinged type with adhesive mounting, distinct from snap-on or saddle bead variants within the same product family.

Replacement Considerations

SB28B2043AB is listed as a parameter equivalent substitute.
