SB28B2030AT

Overview

The SB28B2030AT is a hinged ferrite core manufactured by Leader Tech Inc., designed for free-hanging cable applications. It utilizes material grade 28 to provide an impedance of 18 Ohms at 100MHz. The component features a circular cross-section with an inner diameter of 0.350 inches (8.90mm). Its physical dimensions include a length of 1.098 inches (27.90mm) and a width/height of 0.350 inches (8.90mm). The unit employs a snap-on hinge design for secure attachment around cables.

Feature Summary

• Hinged snap-on design allows for easy installation around existing cables without disconnection
• Utilizes material grade 28 composition for specific high-frequency noise suppression characteristics
• Free-hanging configuration enables flexible mounting in various spatial orientations

Applications

• Suppression of electromagnetic interference on round cables
• Noise filtering in electronic equipment wiring harnesses
• Common mode choke applications for signal integrity improvement

Procurement Notes

Verify the exact part number suffix AT against manufacturer documentation to confirm specific packaging or material variations. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary. Ensure the inner diameter matches the target cable bundle size before procurement to guarantee proper fit and performance.

Selection Notes

Select this component when a circular ferrite core with a 0.350-inch inner diameter is required. The 18 Ohm impedance at 100MHz suits specific frequency ranges; verify this aligns with the noise spectrum. The hinged design is preferred over split cores for repeated access needs. Compare material grade 28 properties against alternative grades if higher impedance at different frequencies is needed.

Part Context

This component belongs to the Leader Tech Inc. ferrite core product line, specifically within the category of clamp-on or snap-on cores. These components are distinct from bead-type or flat cable ferrites, offering a robust solution for cylindrical wire bundles. The product serves as a passive EMI suppression element in electronic assemblies.

Replacement Considerations

SS28B2034K is listed as a parameter equivalent substitute by Leader Tech Inc. Verify dimensional compatibility and impedance curves before substitution.
