SB28B3500

Overview

The SB28B3500 is a hinged, snap-on free-hanging ferrite core manufactured by Leader Tech Inc. It features an inner diameter of 3.000 inches (76.20mm) and an outer dimension of 3.406 inches wide by 0.252 inches high (86.50mm x 6.40mm). The component provides an impedance of 125 Ohms at 100MHz. Designed for cable management, it utilizes a hinged mechanism for easy installation around existing wiring without disconnection.

Feature Summary

• Hinged snap-on design allows for installation on cables without disconnecting connections
• Free-hanging configuration enables flexible mounting in various orientations
• High impedance value of 125 Ohms at 100MHz for effective noise suppression

Applications

• EMI shielding for interconnect cables
• Noise suppression in electronic enclosures
• Cable management in industrial control systems

Procurement Notes

Verify the specific part number suffix to ensure correct dimensions and impedance ratings. Confirm that the hinged mechanism is intact and functional upon receipt. Check datasheet specifications for temperature range and material composition to ensure compatibility with the operating environment. Ensure packaging protects the ferrite core from physical damage during transit.

Selection Notes

Select this component when large diameter cables require EMI suppression without permanent modification. The 3.000-inch ID accommodates thick cable bundles. The hinged design is critical for applications where cable disconnection is impractical or prohibited. Verify that the 125 Ohm impedance matches the frequency spectrum of the interference being mitigated.

Part Context

Leader Tech Inc. specializes in EMI shielding products for circuit boards, enclosures, and interconnects. This ferrite core belongs to their FerriShield line, designed to mitigate electromagnetic interference along cabling paths. The company emphasizes US manufacturing and innovative shielding solutions for robust electronic designs.

Replacement Considerations

The SB28B3500AB is a related variant with identical electrical characteristics but potentially different housing or marking details. Verify dimensional compatibility before substitution. No other direct substitutes are confirmed in public documentation.
