CS28B1642

Overview

The CS28B1642 is a split-core ferrite clamp-on component manufactured by Leader Tech Inc. It features a hinged design for easy installation around existing cables without disconnection. The core material is designated as type 28, providing specific magnetic properties for high-frequency noise suppression. Key physical dimensions include an inner diameter of 7.16 mm (0.282 inches) and an outer diameter of 21.34 mm (0.840 inches). The unit has a length of 21.64 mm (0.852 inches). At a frequency of 100 MHz, the component exhibits an impedance of 100 ohms.

Feature Summary

• Hinged snap-on construction allows for rapid installation on live cables
• Split core design facilitates retrofitting to existing wiring harnesses
• Type 28 ferrite material optimized for broadband noise absorption

Applications

• Suppression of electromagnetic interference in data communication lines
• Noise reduction on power supply cables in electronic equipment
• EMI mitigation in automotive wiring systems

Procurement Notes

Verify that the target cable diameter does not exceed the 7.16 mm inner diameter specification to ensure proper fit. Confirm that the application environment temperature remains within the operational limits defined in the official datasheet. Check RoHS compliance status if required by local regulations. Ensure the hinge mechanism is fully closed to maintain shielding effectiveness.

Selection Notes

Select this model when post-production cable modification is necessary. The split design distinguishes it from solid toroidal cores requiring wire threading. Choose based on the required impedance at the specific noise frequency; verify that 100 ohms at 100 MHz aligns with the system's EMI profile. Consider the physical size constraints relative to the available space around the cable bundle.

Part Context

This component belongs to the Leader Tech Ferrishield series of cable ferrites. These components are engineered for EMI/RFI suppression in various industrial and commercial applications. The product line includes both solid and split-core variants, with the CS28B1642 representing the split-core category designed for convenience and flexibility during assembly or maintenance phases.

Replacement Considerations

Direct substitutes must match the 7.16 mm inner diameter and 100-ohm impedance at 100 MHz. Verify that alternative split-core ferrites utilize compatible materials for similar frequency performance. Ensure mechanical compatibility with the hinge and locking mechanism if retention force is critical.
