SB28B0071AT

Overview

The SB28B0071AT is a hinged snap-on ferrite core manufactured by Leader Tech Inc. designed for EMI suppression on interconnect cables. It features a free-hanging configuration with an inner diameter of 13.00 mm (0.512 inches) and outer dimensions of 12.70 mm width by 3.30 mm height. The component provides an impedance of 23 Ohms at 100 MHz, offering effective noise reduction for signal and power lines in electronic assemblies.

Feature Summary

• Hinged snap-on design allows for easy installation onto existing cables without disconnection
• Provides targeted electromagnetic interference suppression through high-impedance ferrite material
• Free-hanging form factor accommodates various cable diameters within specified limits

Applications

• Suppression of common-mode noise on computer peripheral cables
• EMI mitigation for internal wiring in electronic enclosures
• Noise filtering for communication interface cables

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet to ensure compatibility with target cable diameters. Confirm RoHS compliance status if required by project specifications. Ensure the hinged mechanism integrity is maintained during handling to prevent premature opening or damage to the ferrite core structure.

Selection Notes

Select this component when a non-invasive cable solution is required for EMI control. The snap-on design eliminates the need to disconnect cables during assembly. Consider the operating frequency range where the 23 Ohm impedance is effective. Ensure the cable diameter falls within the 13.00 mm inner diameter specification for proper fit and magnetic coupling efficiency.
