28B0275-000

Overview

The Laird-Signal Integrity Products 28B0275-000 is a solid, free-hanging ferrite core designed for cable and wiring applications. It features a round design with an inner diameter of 3.80mm (0.150 inches) and an outer diameter of 7.00mm (0.276 inches). The component has a length of 13.50mm (0.531 inches) and provides an impedance of 146 Ohms at 100MHz. Constructed from material grade 28, it serves as a passive filter to suppress electromagnetic interference on cables.

Feature Summary

• Solid construction for durable cable mounting
• Free-hanging installation type for flexible application
• Round geometry suitable for various wire diameters

Applications

• Cable and wiring EMI suppression
• Signal integrity enhancement in electronic assemblies
• Passive filtering for high-frequency noise reduction

Procurement Notes

Verify the specific impedance tolerance and material composition against the official datasheet before integration. Confirm that the inner diameter accommodates the target cable size without excessive friction or looseness. Ensure compliance with relevant environmental regulations such as RoHS status if required by the end product specifications.

Selection Notes

Select this component when a robust, non-split ferrite core is required for permanent cable treatment. The 3.80mm inner diameter limits usage to cables within this constraint. Consider the 146 Ohm impedance profile for the specific frequency range of interest, typically around 100MHz, to ensure effective noise attenuation.

Part Context

This part belongs to the 28B series of ferrite cores from Laird-Signal Integrity Products. These components are categorized under passive filters and are distinct from chip ferrite beads or split-core designs. The series offers various dimensions and impedance values to suit different cable sizes and frequency requirements.

Replacement Considerations

Direct substitutes include the 28B0157-100, which shares similar characteristics but differs in physical dimensions and impedance. Verify compatibility regarding inner diameter and mounting constraints before substitution.
