SB28B2039AB

Overview

The SB28B2039AB is a hinged cable ferrite core manufactured by Leader Tech Inc. It features a flat design with an inner diameter of 0.512 inches (13.00 mm) and an outer dimension of 1.398 inches wide by 0.701 inches high (35.50 mm x 17.80 mm). The component has a length of 1.500 inches (38.10 mm) and provides an impedance of 245 Ohms at 100 MHz. Constructed from material grade 28, it utilizes a snap-fit hinge mechanism for secure installation on cables.

Feature Summary

• Hinged snap-fit design allows for easy installation and removal around existing cables without disconnection
• Flat profile construction accommodates specific spatial constraints in electronic assemblies
• Material grade 28 composition provides targeted electromagnetic interference suppression characteristics

Applications

• Suppression of electromagnetic interference on data transmission lines
• Noise filtering for power supply cables in sensitive electronic equipment
• EMI mitigation in telecommunications infrastructure components

Procurement Notes

Verify the exact part number suffix to ensure compatibility with required hinge mechanisms and impedance specifications. Confirm that the inner diameter matches the target cable bundle dimensions prior to procurement. Check manufacturer documentation for RoHS compliance status and environmental classifications relevant to the deployment region. Ensure storage conditions align with manufacturer recommendations to maintain material integrity before installation.

Selection Notes

Select this component when a non-invasive, reusable ferrite solution is required for cables with diameters up to 13.00 mm. The 245 Ohm impedance at 100 MHz indicates suitability for higher frequency noise attenuation compared to lower impedance alternatives. Consider the physical dimensions and flat shape when evaluating clearance within the device enclosure or cable management system.

Part Context

This component belongs to the Leader Tech Inc. SB28 series of cable ferrites. The series offers various sizes and impedance values tailored for different cable diameters and frequency requirements. The SB28B2039AB specifically addresses applications requiring a larger bore size with high impedance characteristics in a hinged format.

Replacement Considerations

SB28B2039 is a parameter-equivalent alternative from Leader Tech Inc. Verify dimensional and impedance tolerances before substitution. Cross-manufacturer replacements require careful validation of material properties and mechanical fit.
