CW28B1984

Overview

The CW28B1984 is a hinged ferrite core manufactured by Leader Tech Inc., designed for electromagnetic interference suppression. It features a circular shape with an internal diameter of 13.21mm and exhibits an impedance of 62 ohms at 100MHz. The component utilizes material grade 28 and is constructed as a free-hanging unit with a snap-lock hinge mechanism. Its external dimensions are optimized for standard cable applications, providing effective noise reduction in electronic systems without requiring permanent mounting hardware.

Feature Summary

• Hinged design allows for easy installation around existing cables without disconnection
• Utilizes high-permeability ferrite material for effective broadband noise attenuation
• Free-hanging configuration provides flexible deployment options in various enclosures

Applications

• Suppression of common-mode noise on data communication cables
• EMI mitigation in computer peripheral connections
• Noise filtering for industrial control signal lines

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet to ensure compatibility with target cable diameters. Confirm that the hinged closure mechanism meets the mechanical requirements of the installation environment. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a non-invasive solution for cable noise suppression is required. Ensure the inner diameter accommodates the maximum cable bundle size with sufficient clearance. Consider the operating frequency range where the 62-ohm impedance provides optimal attenuation performance for the specific application.

Part Context

This part belongs to the Leader Tech Inc. ferrite core family, specifically engineered for EMI/RFI suppression.
