28R0984-000

Overview

The Laird-Signal Integrity Products 28R0984-000 is a solid ferrite core designed for cable filtering applications. It features an internal slot dimension of 18mm by 0.9mm, accommodating ribbon and flex cables. The component utilizes Material 28 to achieve an impedance of 220 ohms at 100 MHz. Its physical dimensions are characterized by a specific cross-section optimized for flat cabling.

Feature Summary

• Solid construction provides mechanical stability for cable clamping
• Material 28 formulation ensures high-frequency EMI suppression
• Slot geometry specifically engineered for ribbon and flex cables

Applications

• Suppression on ribbon cables
• Filtering for flex cables
• General signal integrity enhancement

Procurement Notes

Verify the internal slot dimensions (18mm x 0.9mm) match the target cable thickness before procurement. Confirm that Material 28 meets the required frequency response specifications for the application. Ensure the solid core design aligns with the assembly method for the specific cable type.

Selection Notes

Select this component when dealing with flat cabling requiring a 18mm width and 0.9mm height clearance. The 220 ohm impedance at 100 MHz indicates suitability for higher frequency noise reduction compared to lower impedance cores. Consider the solid design for permanent installation rather than split-core alternatives.

Part Context

This part belongs to the Laird 28R series of cable ferrites. It is distinct from bead inductors or toroidal cores due to its solid rectangular profile. The series focuses on providing passive EMI filtering for interconnects without requiring soldering.

Replacement Considerations

Direct substitutes must match the 18x0.9mm slot size and 220 ohm @ 100MHz impedance. Verify material composition compatibility.
