28R0965-100

Overview

The Laird-Signal Integrity Products 28R0965-100 is a solid, free-hanging ferrite core designed for electromagnetic interference suppression. It utilizes Material 28 technology to provide high impedance characteristics in the radio frequency spectrum. The component features a circular geometry with an inner diameter of 0.374 inches (9.50mm) and an outer diameter of 0.965 inches (24.50mm). Its physical length measures 1.00 inch (25.40mm). At a standard test frequency of 100MHz, the core exhibits an impedance value of 210 ohms, ensuring effective noise attenuation for cable applications.

Feature Summary

• Solid construction provides mechanical stability for free-hanging installation on cables
• Material 28 composition delivers high magnetic permeability for broadband noise suppression
• Circular cross-section design accommodates various wire gauges within specified bore dimensions

Applications

• Suppression of common-mode noise on power supply cables
• Filtering of radio frequency interference on data transmission lines
• EMI mitigation in industrial control wiring harnesses

Procurement Notes

Verify that the required impedance specification aligns with Material 28 characteristics rather than alternative formulations. Confirm that the inner diameter meets the maximum cable bundle size requirements for the specific application. Ensure compliance with RoHS3 directives if environmental regulations apply to the final assembly. Check lead times as manufacturing schedules may vary based on material availability.

Selection Notes

Select this component when a robust, non-split ferrite solution is required for permanent cable installations. The solid design prevents accidental opening compared to snap-fit alternatives. Evaluate the 210-ohm impedance at 100MHz against the target noise frequencies to ensure adequate attenuation. Consider the physical dimensions to verify clearance constraints within the equipment enclosure or cable routing path.

Part Context

This part belongs to the 28R series of solid ferrite cores from Laird-Signal Integrity Products. The series is characterized by fixed internal diameters and standardized lengths to simplify inventory management. These components are engineered specifically for signal integrity enhancement in environments prone to electromagnetic disturbances.

Replacement Considerations

Direct substitutes include other solid ferrite cores with identical Material 28 properties and matching dimensional tolerances. Verify that any alternative maintains the same 210-ohm impedance profile at 100MHz to preserve circuit performance.
