SB28B3500AB

Overview

The SB28B3500AB is a hinged ferrite core manufactured by Leader Tech Inc., designed for flat cable applications. It features an internal diameter of 76.2 mm and an impedance of 125 Ohms at 100 MHz. The component measures 86.50 mm in width and 6.40 mm in height, with a total length of 76.20 mm. It utilizes a snap-on installation method for free-hanging deployment on ribbon cables.

Feature Summary

• Hinged design allows for easy snap-on installation around cables
• Provides electromagnetic interference suppression via high impedance characteristics
• Adhesive backing option available for secure mounting

Applications

• Suppression of noise on flat ribbon cables
• EMI reduction in electronic enclosures
• Signal integrity enhancement in data transmission lines

Procurement Notes

Verify the specific suffix (e.g., AB) to confirm the presence of adhesive backing, as standard versions may differ. Confirm impedance specifications match the target frequency range of 100 MHz. Ensure the internal diameter accommodates the specific flat cable thickness and width requirements of the application.

Selection Notes

Select this model when a large internal diameter is required for wide ribbon cables. The hinged mechanism facilitates assembly without disconnecting cables. Consider the adhesive variant if vibration resistance or fixed positioning is necessary compared to free-hanging configurations.

Part Context

This component belongs to the SB28 series of ferrite cores from Leader Tech Inc., which specializes in EMI shielding solutions. The series includes various shapes such as saddle beads and plates, catering to diverse cable management and shielding needs in industrial and commercial electronics.

Replacement Considerations

Cross-reference with SA28B3500 for similar dimensions but verify installation type differences. Check SB28B0121AB for alternative mounting styles, noting significant dimensional variations.
