RC28B4340

Overview

The RC28B4340 is a ferrite clamp-on core manufactured by Leader Tech Inc., designed for flat ribbon cables. It features a fully enclosed nylon case housing the ferrite material. The component has an outside length of 117.1 mm, an outside width of 33.3 mm, and an outside height of 19.2 mm. The internal cavity height is 2.6 mm, accommodating specific flat cable profiles. This assembly provides electromagnetic interference suppression for high-density interconnects.

Feature Summary

• Fully enclosed nylon case design
• Compatible with flat ribbon cables up to 64-conductor widths

Applications

• EMI suppression for flat ribbon cables
• High-density interconnect shielding
• Cable harness noise reduction

Procurement Notes

Verify the exact physical dimensions against the target cable bundle before procurement. Confirm that the internal height of 2.6 mm accommodates the specific flat cable thickness. Ensure the fully enclosed nylon casing meets the environmental and mechanical requirements of the installation site. Cross-reference the manufacturer part number RC28B4340 with official distributor catalogs to confirm current availability and compliance status.

Selection Notes

Select this component when a robust, fully enclosed ferrite solution is required for flat cables. The design supports cables with up to 64 conductors, making it suitable for wide data buses. Consider the external dimensions of 117.1 mm by 33.3 mm for spatial constraints in the enclosure. The enclosed structure offers additional protection compared to open clamshell designs.

Part Context

Leader Tech Inc. produces the FerriShield line of EMI shielding products. The RC28B4340 belongs to the category of ferrite clamp-on cores specifically engineered for flat cables. These components are utilized to mitigate electromagnetic interference in electronic assemblies where standard round cable ferrites are unsuitable due to cable geometry.
