28B3149

Overview

The Leader Tech Inc. 28B3149 is a solid cable tie ferrite core designed for electromagnetic interference suppression. It features a rectangular cross-section with an internal length of 68.60 mm and an internal height of 1.90 mm. The external dimensions measure 80.00 mm in width and 12.79 mm in height. This component provides an impedance of 93 Ohms at 100 MHz, making it suitable for high-frequency noise attenuation on flat cables.

Feature Summary

• Solid construction designed for secure attachment to cables via integrated tie mechanism
• Provides significant impedance at 100 MHz to suppress high-frequency electromagnetic interference
• Rectangular geometry optimized for flat ribbon cable applications

Applications

• Suppression of EMI/RFI noise on flat data cables
• Signal integrity enhancement in industrial control systems
• Noise filtering in telecommunications equipment cabling

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet before integration. Confirm that the cable thickness falls within the core's internal height tolerance to ensure proper fit. Check RoHS compliance status if required by project specifications. Ensure the adhesive or tie mechanism meets environmental operating conditions.

Selection Notes

Select this component when a fixed-impedance solution for flat cables is required without the need for assembly hardware. Consider the 93 Ohm @ 100 MHz rating for typical digital signal noise profiles. Evaluate the physical size constraints against available routing space in the enclosure. Compare against split-core alternatives if field installation flexibility is necessary.

Part Context

This part belongs to the Leader Tech Inc. family of cable ferrites, which are specialized passive components for EMI suppression. Unlike standard snap-on cores, these units are engineered specifically for flat cable geometries. They serve as critical elements in maintaining signal integrity by attenuating common-mode noise generated by high-speed digital circuits.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility based on identical impedance characteristics and physical dimensions when sourcing alternatives.
