SB28B2039

Overview

The SB28B2039 is a saddle bead ferrite component manufactured by Leader Tech Inc. It features a hinged design with an internal diameter of 13 mm and an impedance of 245 Ohms at 100 MHz. The unit measures 38.1 mm in length, 6.5 mm in width, and 17.8 mm in thickness. This component belongs to the SB28 series and is packaged in bulk quantities.

Feature Summary

• Hinged saddle bead construction for secure cable retention
• High impedance ferrite material for EMI suppression
• Adhesive-free design allowing flexible mounting options

Applications

• Suppression of electromagnetic interference on single cables
• RFI filtering in electronic equipment enclosures
• Cable bundle noise reduction in industrial systems

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as SB28B2039AB include adhesive backing while standard versions may not. Confirm physical dimensions and impedance requirements against the official datasheet to ensure compatibility with existing cable assemblies and enclosure constraints before finalizing procurement.

Selection Notes

Select this component based on the required inner diameter of 13 mm to fit target cables. Ensure the 245 Ohm impedance at 100 MHz meets the specific frequency range of the noise being suppressed. Consider the hinged mechanical design for ease of installation on pre-routed cables without disconnecting them.
