28B1775-1

Overview

The Leader Tech Inc. 28B1775-1 is a solid flat ferrite cable core designed for electromagnetic interference suppression in ribbon cable applications. It features a Type 28 material composition with an impedance of 151 Ohms measured at a test frequency of 100 MHz. The component has internal dimensions of 34.4 mm length by 1.52 mm height, and external dimensions of 45.1 mm length by 28.6 mm width and 12.7 mm height. It is supplied in bulk packaging.

Feature Summary

• Solid construction made from Type 28 ferrite material for effective noise attenuation
• Flat geometry specifically engineered to accommodate flat ribbon cables
• Integrated shock mount adhesive for secure attachment to cable assemblies

Applications

• Electromagnetic interference suppression on flat ribbon cables
• Signal integrity enhancement in data transmission lines
• Noise filtering in electronic equipment cabling

Procurement Notes

Verify the exact part number suffix against official manufacturer documentation to ensure correct impedance and physical specifications. Confirm that the adhesive type matches application requirements. Check RoHS compliance status through the official datasheet before procurement. Ensure the bulk packaging format aligns with assembly handling capabilities.

Selection Notes

Select this component when flat ribbon cable compatibility is required alongside specific high-frequency noise characteristics. The 151 Ohm impedance at 100 MHz defines its frequency response profile. Consider the external dimensions to ensure adequate clearance within the enclosure. Verify that the solid core design meets mechanical stress requirements compared to split-core alternatives.

Part Context

This component belongs to the LeaderTech ferrite cable core product line, which specializes in EMI suppression solutions. The '28' designation indicates the use of Type 28 ferrite material, known for specific permeability and loss characteristics. The '-1' suffix typically denotes specific dimensional or mounting variations within the series.

Replacement Considerations

SM28B1775 offers similar dimensions but provides 293 Ohms impedance. SM28B2170-1 provides 176 Ohms impedance with different internal dimensions. Verify impedance requirements and physical fit before substituting.
