28B0785

Overview

The Leader Tech Inc. 28B0785 is a solid rectangular ferrite cable core designed for EMI suppression in flat ribbon cables. It provides an impedance of 170 Ohms at a test frequency of 100 MHz. The component features an internal length of 13.1 mm and an external length of 19.9 mm. Its cross-sectional dimensions include an internal width of 13.1 mm by height of 3.7 mm, and an external width of 27.9 mm by height of 11.3 mm. The unit weighs approximately 42.437 grams and is supplied in bulk packaging.

Feature Summary

• Solid rectangular construction for secure mounting on flat ribbon cables
• Provides high impedance to suppress electromagnetic interference
• Adheres to RoHS compliance standards

Applications

• EMI suppression on flat ribbon cables
• Signal integrity enhancement in electronic assemblies
• Cable filtering in industrial equipment

Procurement Notes

Verify the specific impedance rating of 170 Ohms at 100 MHz against your design requirements. Confirm that the physical internal dimensions of 13.1 mm by 3.7 mm accommodate the target cable thickness. Ensure the solid core style matches the intended mounting method for flat ribbon cables rather than round wires.

Selection Notes

Select this component when dealing with flat ribbon cables requiring significant common-mode noise reduction. The solid geometry offers stability compared to split cores. Consider the external dimensions to ensure adequate clearance within the enclosure. Verify compatibility with the operating temperature range specified in the official datasheet.

Part Context

This part belongs to the ferrite cable core category from Leader Tech Inc. It is distinct from saddle beads or absorbers due to its solid, pass-through design. The product line focuses on passive EMI/RFI suppression components for various cable types.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer catalogs for equivalent impedance and dimension specifications.
