28B0125-000

Overview

The Laird-Signal Integrity Products 28B0157-100 is a solid cable ferrite core designed for electromagnetic interference suppression. It features an impedance of 121 Ohms at 100 MHz and utilizes Material 28. The component has a free-hanging installation type with circular geometry. Internal dimensions are 0.079 inches (2.00 mm) in diameter, while the external diameter measures 0.157 inches (4.00 mm). The total length is 0.394 inches (10.00 mm).

Feature Summary

• Solid construction utilizing Material 28 for effective high-frequency noise attenuation.
• Free-hanging design allows for easy installation onto existing cables without modification.
• Circular geometry provides uniform magnetic properties around the conductor.

Applications

• Suppression of common mode noise on data cables.
• EMI filtering for power supply lines.
• Signal integrity enhancement in electronic assemblies.

Procurement Notes

Verify the specific impedance requirement of 121 Ohms at 100 MHz against your circuit's noise profile. Confirm that the inner diameter of 2.00 mm accommodates the target cable gauge. Ensure the solid core design meets the mechanical constraints of the assembly. Check RoHS3 compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a solid, non-split ferrite core is preferred over split types for permanent installations. The 2.00 mm inner diameter limits usage to smaller gauge wires. Consider the 10.00 mm length for space availability. Material 28 offers specific frequency characteristics suitable for general EMI suppression tasks.

Part Context
