CS28B0937

Overview

The CS28B0937 is a hinged ferrite core manufactured by Leader Tech Inc., designed for free-hanging cable applications. It utilizes Material 28 to provide an impedance of 117 Ohms at 100MHz. The component features a circular shape with a hinged snap-on design for easy installation. Internal dimensions include a diameter of 0.425 inches (10.80mm), while the outer dimensions measure 1.079 inches (27.40mm) in diameter and 1.220 inches (31.00mm) in length.

Feature Summary

• Hinged snap-on design allows for quick installation around existing cables without disconnection.
• Free-hanging mounting style provides flexible placement options on wires and harnesses.
• Constructed from Material 28 ferrite composition to effectively suppress electromagnetic interference.

Applications

• Suppression of common-mode noise on data cables
• EMI filtering for high-frequency signal lines
• Cable harness noise reduction in electronic assemblies

Procurement Notes

Verify the specific material grade and impedance tolerance against the official datasheet before integration. Confirm that the internal diameter accommodates the target cable bundle size with appropriate clearance. Ensure compliance with RoHS3 standards if required by the end product specifications. Cross-reference the part number with manufacturer documentation to confirm current production status.

Selection Notes

Select this component when a snap-on ferrite core is required for cables with diameters up to 10.80mm. The Material 28 composition is suitable for frequencies around 100MHz, offering 117 Ohms of impedance. Consider the physical length of 31.00mm for spatial constraints within the assembly. The hinged design is preferred over split cores for repeated access or ease of maintenance.

Part Context

This component belongs to the category of cable ferrites used for EMI/RFI suppression. It serves as a passive filter element to attenuate high-frequency noise on conductors. The hinged construction distinguishes it from solid or split-core alternatives, offering convenience during assembly processes while maintaining effective magnetic coupling around the cable.
