28B0339-000

Overview

The 28B0339-000 is a solid, free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It belongs to the 28B series and utilizes Material 28 for EMI suppression. The component exhibits an impedance of 143 Ohms at 100MHz. Its physical dimensions include an inner diameter of 0.150 inches (3.80mm), an outer diameter of 0.339 inches (8.60mm), and a length of 0.394 inches (10.00mm).

Feature Summary

• Solid construction designed for cable and wire applications.
• Free hanging mounting type allows for easy installation on existing wiring.
• Material 28 composition provides broadband noise suppression capabilities.

Applications

• Suppression of unintended signals on cables.
• Reduction of electromagnetic interference emitted from wires.
• Common mode filtering in signal integrity circuits.

Procurement Notes

Verify the specific part number 28B0339-000 against official Laird datasheets to ensure compatibility with required impedance and dimensional specifications. Confirm RoHS compliance status as regulatory requirements may vary by region and manufacturing batch. Cross-reference internal diameter measurements to guarantee proper fit over target cable assemblies before finalizing procurement orders.

Selection Notes

Select this component when broadband EMI suppression is required for cables with an inner diameter of approximately 3.80mm. The 143 Ohm impedance at 100MHz suits general noise reduction needs. Ensure the free-hanging design aligns with mechanical constraints, as it lacks snap-fit or clip mechanisms found in split-core alternatives.

Part Context

This ferrite core is part of the 28B series from Laird-Signal Integrity Products, which offers various solid cores for post-assembly operations. The series utilizes specific ferrite materials optimized for high-frequency noise attenuation. These components are categorized under passive filters and are distinct from split-core designs intended for retrofitting without cable disconnection.

Replacement Considerations

Direct substitutes within the same series include parts with matching 3.80mm inner diameters and similar impedance characteristics. Verify that alternative models maintain the solid construction and Material 28 composition to preserve performance equivalence in EMI suppression applications.
