Overview
The Leader Tech SB28B0121AT is a hinged cable ferrite from the SB28 series, designed for EMI suppression. It features a flat saddle bead construction with a top-mount adhesive installation style. The component utilizes Material 28 to provide an impedance of 35 Ohms at 100MHz. Physical dimensions include a length of 12.7 mm, a width of 0.7 mm, and a thickness of 3.3 mm. It is supplied in bulk packaging.
Feature Summary
- Hinged snap-on design for easy cable installation
- Top-mount adhesive backing for secure positioning
- Material 28 composition for targeted high-frequency noise attenuation
Applications
- Suppression of electromagnetic interference on data cables
- Noise reduction in telecommunications equipment wiring
- EMI control in computer peripheral connections
Procurement Notes
Verify the specific suffix 'AT' corresponds to the top-mount adhesive variant, as other suffixes may indicate different mounting styles or material properties. Confirm that the 35 Ohm impedance rating aligns with the target frequency spectrum of the application. Ensure compatibility with the cable diameter intended for use within the ferrite core.
Selection Notes
Select this component when a low-profile, self-adhesive solution is required for rapid assembly. The 35 Ohm impedance at 100MHz suits applications targeting higher frequency noise compared to standard 100 Ohm variants. Consider the physical constraints of the enclosure, as the 12.7 mm length and 3.3 mm height are compact.
Part Context
This part belongs to the LeaderTech SB28 family of saddle beads, which are widely used for cable shielding. The SB28 series offers various impedance levels and mounting options, including bottom and top adhesive configurations, to address diverse EMI/RFI mitigation requirements in electronic assemblies.
Replacement Considerations
SB28B0121AB is a parameter-equivalent alternative but features bottom-mount adhesive instead of top-mount. Verify that the adhesive orientation difference does not interfere with the mechanical layout of the target assembly.
