28B0472-090

Overview

The 28B0472-090 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It provides an impedance of 272 Ohms at 100 MHz. The component features a cylindrical geometry with an inside diameter of 3.6 mm, an outside diameter of 12.0 mm, and a length of 20.0 mm.

Feature Summary

• Solid construction for stable electromagnetic interference suppression
• Free-hanging design allows easy installation on cables without adhesives
• Cylindrical shape accommodates various cable diameters within the bore size

Applications

• Suppression of common mode noise on power cables
• Filtering high-frequency interference on data transmission lines
• Compliance enhancement for electronic equipment EMC requirements

Procurement Notes

Verify the specific impedance value of 272 Ohms at 100 MHz against your circuit requirements. Confirm that the 3.6 mm inner diameter fits the target cable bundle securely. Ensure the material composition meets RoHS3 standards if required by your manufacturing process.

Selection Notes

Select this component when a non-adhesive, reusable ferrite solution is needed. The 3.6 mm bore size limits application to smaller gauge cables. Consider the physical length of 20 mm for available space constraints in the assembly area.

Part Context

This part belongs to the ferrite cable core category from Laird-Signal Integrity Products. It serves as a passive component for EMI mitigation. Unlike surface-mount beads, it is designed for direct clamping onto existing wire harnesses during assembly or retrofitting.
