USB28B2034K

Overview

The USB28B2034K is a hinged ferrite core manufactured by Leader Tech Inc., designed for cable bundle noise suppression. It utilizes Material 28, providing an impedance of 220 Ohms at 100 MHz. The component features a circular split-core design with a snap-fit closure mechanism. Key dimensions include an inner diameter of 6.40 mm (0.251 inches) and external dimensions of 31.80 mm in length, 31.80 mm in width, and 14.90 mm in height.

Feature Summary

• Hinged snap-fit design allows for installation on existing cables without disconnection
• Material 28 composition provides high impedance characteristics for EMI suppression
• Circular cross-section accommodates round cable bundles

Applications

• Suppression of electromagnetic interference on computer peripheral cables
• Noise reduction on power supply cords and data transmission lines
• EMI filtering for industrial equipment cabling

Procurement Notes

Verify the specific suffix 'K' against the manufacturer's current datasheet to confirm packaging or material variations. Ensure the inner diameter specification matches the target cable bundle diameter to guarantee proper fit and magnetic coupling efficiency. Cross-reference the part number with official Leader Tech documentation to validate availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a non-invasive solution for cable noise suppression is required. The hinged design facilitates retrofitting onto installed wiring harnesses. Verify that the 6.40 mm inner diameter is sufficient for the maximum cable bundle thickness. Confirm that the Material 28 impedance profile aligns with the frequency range of the interference being mitigated.

Part Context

This part belongs to the Leader Tech Ferrishield series of clamp-on ferrite cores. These components are engineered for broadband noise suppression in electronic systems. The USB prefix typically denotes a specific form factor within the company's catalog, characterized by its split-core geometry and standardized dimensions for common cable sizes.

Replacement Considerations

Publicly confirmed substitute part numbers include USB28B2034 and USB28B2034A from Leader Tech Inc. These variants share parameter equivalence. Verify mechanical compatibility and impedance specifications before substitution.
