SM28B2170-1

Overview

The SM28B2170-1 is a solid flat ribbon cable ferrite core manufactured by LeaderTech Inc. It features a hinged snap-on design for easy installation on flat cables. The component provides an impedance of 176 Ohms at a test frequency of 100 MHz. Internal dimensions are 43.7 mm in length and 1.3 mm in height, while external dimensions measure 55.1 mm in length and 13.5 mm in height. The material composition is designated as type 28.

Feature Summary

• Hinged snap-on construction allows for quick attachment to flat ribbon cables without disconnection.
• Solid flat geometry designed specifically for uniform coverage over wide signal traces.
• Engineered with type 28 ferrite material to provide targeted high-frequency noise suppression.

Applications

• Noise suppression on parallel data buses
• EMI reduction on flat ribbon cable assemblies
• Signal integrity enhancement in digital interconnects

Procurement Notes

Verify the specific impedance value of 176 Ohms at 100 MHz against your system requirements before ordering. Confirm that the internal width of 43.7 mm accommodates the target flat cable thickness. Ensure the hinged mechanism is compatible with the assembly process. Check RoHS compliance status if required by your manufacturing standards. Validate the external dimensions fit within the available enclosure space.

Selection Notes

Select this component when a non-invasive solution for flat cable EMI suppression is required. The hinged design eliminates the need to thread cables through fixed cores. Choose based on the 176 Ohm impedance profile suitable for the specific frequency range of interference. Ensure the physical size matches the ribbon cable width and available clearance. Consider the solid construction for durability during repeated handling or vibration.

Part Context

This part belongs to the LeaderTech SM28B series of flat ribbon cable ferrites. These components are engineered for high-density electronic environments where space is limited. The series offers various impedance values and sizes to match different cable configurations. The SM28B2170-1 specifically targets applications requiring moderate impedance with a compact footprint.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing designs if considering alternative manufacturers. Ensure any replacement maintains the same hinged form factor and impedance characteristics.
