SB28B2041

Overview

The SB28B2041 is a hinged snap-on cable ferrite filter manufactured by Leader Tech Inc. Designed for electromagnetic interference (EMI) suppression, this component features a flat type construction with an inner diameter of 0.402 inches (10.21 mm). It provides an impedance of 40 Ohms at 100 MHz. The physical dimensions include a length of 1.098 inches and an outer dimension of 0.799 inches width by 0.402 inches height.

Feature Summary

• Hinged snap-on design allows for easy installation on existing cables without disconnection
• Flat type construction optimizes space efficiency in tight electronic enclosures
• Provides effective EMI shielding for interconnect cables

Applications

• Suppression of electromagnetic interference in electronic interconnect cables
• Shielding applications within electronic enclosures
• Circuit board related cable protection

Procurement Notes

Verify the specific part number suffix when ordering, as variants such as SB28B2041AT may exist with identical core specifications but potentially different packaging or minor manufacturing distinctions. Confirm that the required impedance and physical dimensions match the application requirements before finalizing procurement to ensure compatibility with target cable diameters.

Selection Notes

Select this component when a non-invasive solution for cable EMI suppression is required. The snap-on mechanism facilitates rapid assembly and maintenance compared to split-core alternatives that require tools. Ensure the cable diameter falls within the 0.402-inch inner dimension tolerance to guarantee proper magnetic coupling and effective noise attenuation performance.
