CW28B0937

Overview

The CW28B0937 is a hinged ferrite clamp-on core manufactured by Leader Tech Inc. It utilizes Material 28 to provide an impedance of 117 Ohms at 100 MHz. The component features a circular design with a snap-fit closure mechanism for easy installation around cables. Key dimensions include an inner diameter of 10.21 mm, an outer diameter of 28.60 mm, and a length of 14.00 mm. It is designed for free-hanging mounting and complies with RoHS3 standards.

Feature Summary

• Hinged snap-fit design allows for quick installation on existing cable assemblies without disconnection.
• Material 28 composition provides high magnetic permeability for effective noise suppression in the specified frequency range.
• Circular cross-section accommodates round cables and wires within the defined inner diameter limits.

Applications

• Suppression of electromagnetic interference (EMI) on single round cables
• Noise filtering for data transmission lines
• Common mode choke applications for power and signal cables

Procurement Notes

Verify the specific inner diameter requirement against the 10.21 mm specification to ensure proper cable fit. Confirm that the application environment does not exceed the thermal limits associated with Material 28 ferrites. Check for RoHS3 compliance documentation if required by your supply chain regulations. Ensure the hinged mechanism remains secure during operation to maintain consistent magnetic coupling.

Selection Notes

Select this part when a non-invasive solution for EMI suppression on round cables is required. The 117 Ohm impedance at 100 MHz makes it suitable for general-purpose noise reduction. Consider the 10.21 mm inner diameter to ensure compatibility with the target cable bundle size. The hinged design offers convenience over split-core alternatives that require tools for assembly.

Part Context

This component belongs to the Leader Tech Inc. ferrite core family, specifically utilizing Material 28 for balanced performance across a wide frequency spectrum. The CW series denotes hinged or snap-fit configurations, distinguishing it from slide-on or bar-style cores. This design prioritizes ease of retrofitting onto existing wiring harnesses in electronic equipment.

Replacement Considerations

Direct substitutes must match the 10.21 mm inner diameter and 117 Ohm @ 100 MHz impedance profile. Alternative parts using Material 28 are preferred for similar frequency characteristics. Verify that any replacement also features a hinged or snap-fit mechanism if tool-free installation is necessary.
