CS28B4000

Overview

The CS28B4000 is a hinged snap-on ferrite core manufactured by Leader Tech Inc. It features an inner diameter of 1.961 inches (49.80 mm) and an outer diameter of 4.685 inches (119.00 mm). The component has a length of 4.496 inches and provides an impedance of 290 Ohms at 100 MHz. Constructed from material grade 28, it is designed for free-hanging mounting applications.

Feature Summary

• Hinged snap-on design for easy installation around cables
• Fully enclosed nylon case construction
• High impedance performance at 100 MHz

Applications

• EMI suppression for large diameter wires
• RFI filtering for cable assemblies up to 2.0 inch diameter
• Electromagnetic interference shielding in industrial wiring

Procurement Notes

Verify the specific material grade and impedance specifications against the official datasheet before procurement. Confirm that the physical dimensions match the required cable diameter constraints. Ensure the manufacturer is identified as Leader Tech Inc. to guarantee component authenticity and compliance with technical requirements.

Selection Notes

Select this component when dealing with cables exceeding standard ferrite sizes. The 1.961-inch inner diameter accommodates thick wire bundles. The hinged mechanism allows retrofitting without disconnecting cables. Verify that the 290 Ohm impedance at 100 MHz meets the specific noise frequency requirements of the application.

Part Context

This part belongs to the FerriShield line of EMI/RFI shielding products from Leader Tech Inc., a U.S.-based manufacturer specializing in shielding technologies. The CS28B series represents large-diameter cable ferrites designed for robust electromagnetic interference mitigation in demanding environments.

Replacement Considerations
