28B0141-000

Overview

The 28B0141-000 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It provides an impedance of 79 Ohms at 100 MHz. The component features an inner diameter of 1.50 mm and an outer diameter of 3.50 mm, with a length of 3.25 mm. Designed for EMI suppression on cables, it operates without specific electrical ratings as it is a passive magnetic material.

Feature Summary

• Solid construction for effective high-frequency noise attenuation
• Free-hanging design allows easy installation over existing cables
• Optimized impedance characteristics for EMI filtering applications

Applications

• Suppression of electromagnetic interference on data cables
• Noise reduction in power supply lines
• EMI filtering for communication interfaces

Procurement Notes

Verify the exact physical dimensions against your cable specifications to ensure proper fit. Confirm that the 79 Ohm impedance at 100 MHz aligns with your target noise frequency spectrum. Ensure the supplier provides original manufacturer documentation to guarantee material authenticity and performance consistency.

Selection Notes

Select this component when a non-invasive, snap-on solution is required for cable noise suppression. Consider the inner diameter constraint of 1.50 mm to match the cable bundle size. Evaluate if the fixed impedance profile meets the specific EMI requirements of the application compared to adjustable or multi-material alternatives.

Part Context

This ferrite core belongs to Laird-Signal Integrity Products' range of EMI cable cores. These components are designed to complement discrete ferrite beads and chips by offering a solution for finished cables. They serve as critical elements in maintaining signal integrity and compliance with electromagnetic compatibility standards.

Replacement Considerations

Check for equivalent solid ferrite cores with similar impedance curves and compatible inner diameters. Verify that alternative materials offer comparable high-frequency absorption characteristics. Ensure mechanical stability matches the original design requirements.
