28B0071

Overview

The Leader Tech Inc. 28B0071 is a solid rectangular ferrite cable core designed for electromagnetic interference suppression on flat ribbon cables. It features an internal length of 13 mm, an external length of 19.9 mm, and an external width of 27.9 mm. The component has an internal height of 3.7 mm and an external height of 11.3 mm. It provides an impedance of 170 Ohms at a test frequency of 100 MHz. The unit weighs approximately 42.437 grams and is supplied in bulk packaging.

Feature Summary

• Solid rectangular geometry optimized for flat ribbon cable applications
• Provides high impedance characteristics for effective noise attenuation
• Designed for direct clamping onto data lines without adhesive

Applications

• Suppression of electromagnetic interference on flat ribbon cables
• Data line filtering in electronic assemblies
• RFI mitigation in signal transmission paths

Procurement Notes

Verify the specific impedance value of 170 Ohms at 100 MHz against your design requirements. Confirm that the physical dimensions, particularly the internal length of 13 mm and width of 27.9 mm, accommodate the target flat ribbon cable thickness and width. Ensure compliance with RoHS directives if required by your manufacturing standards.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent installation on flat cables. The 170 Ohm impedance rating suits specific frequency ranges for EMI reduction. Consider the bulk packaging format for assembly integration. Compare against split-core alternatives if field installation flexibility is necessary.

Part Context

This part belongs to the LeaderTech ferrite cable cores category, specifically within the solid rectangle sub-type. It is distinct from clamp-on or saddle bead variants. The product line focuses on passive EMI/RFI suppression components for protecting sensitive electronic circuits from conducted noise.
