SB28B1251AB

Overview

The SB28B1251AB is a hinged snap-on ferrite core manufactured by Leader Tech Inc. designed for electromagnetic interference suppression on cables. It features a flat design with an internal diameter of 19.1 mm and an external length of 28.00 mm. The unit provides an impedance of 50 Ohms at 100 MHz and utilizes material grade 28. The component includes an adhesive base for secure mounting and is packaged in bulk quantities.

Feature Summary

• Hinged snap-on design allows for easy installation around existing cables without disconnection
• Integrated adhesive base ensures secure attachment to surfaces or cable bundles
• Flat geometry facilitates compact integration within confined electronic enclosures

Applications

• Suppression of high-frequency noise on data and power cables
• EMI/RFI mitigation in telecommunications equipment
• Noise reduction in computer peripheral connections

Procurement Notes

Verify the specific impedance rating and material composition against project requirements before ordering. Confirm that the adhesive backing meets environmental standards for the intended application. Ensure compatibility with the target cable diameter to maintain effective magnetic coupling and noise suppression performance.

Selection Notes

Select this component when a snap-on ferrite solution is required for cables with diameters near 19.1 mm. The 50 Ohm impedance at 100 MHz suits general EMI suppression needs. Consider the adhesive feature if permanent mounting is preferred over loose clamping. Evaluate space constraints due to the flat profile dimensions.

Part Context

This part belongs to the SB28 series of ferrite components from Leader Tech, which specializes in EMI filtering solutions. The series includes various shapes such as saddle beads and clamp cores. The SB28B1251AB specifically addresses applications requiring convenient installation via its hinged mechanism while maintaining effective high-frequency noise attenuation characteristics.

Replacement Considerations

SB28B0550 is listed as a parameter-equivalent substitute option.
