28R1236-000

Overview

The 28R1236-000 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It provides an impedance of 162 Ohms at 100 MHz. The component features a rectangular slot design with an inside dimension of 23.00mm width by 1.50mm height and an outside dimension of 31.40mm width by 7.75mm height.

Feature Summary

• Solid construction for stable electromagnetic interference suppression
• Free-hanging installation method suitable for cable wrapping
• Rectangular slot geometry designed for specific cable profiles

Applications

• Cable noise suppression in electronic assemblies
• Electromagnetic interference filtering for signal lines
• Radio frequency interference mitigation in wiring harnesses

Procurement Notes

Verify the exact physical dimensions against the target cable diameter before procurement, as the 23.00mm internal width is specific. Confirm that the solid core material meets the required environmental standards for the intended deployment environment. Ensure compatibility with existing assembly processes for free-hanging components.

Selection Notes

Select this part when a high-impedance solution is required for cables fitting within the 23.00mm x 1.50mm slot. Consider the solid core construction for durability compared to split cores. Evaluate the 162 Ohm impedance profile at 100 MHz against the noise spectrum of the application to ensure effective attenuation.

Part Context

This ferrite core belongs to Laird's performance materials portfolio focused on signal integrity. It serves as a passive component for managing electromagnetic emissions in wiring systems. The product supports designs requiring robust noise reduction without active circuitry integration.

Replacement Considerations

Direct substitutes include other Laird ferrite cores with similar impedance and dimensional constraints. Verify cross-compatibility based on internal slot size and operating frequency characteristics before substitution.
