28B1225-300

Overview

The 28B1225-300 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It features an impedance of 110 Ohms at 100MHz and utilizes Material 28. The component has a circular design with an inner diameter of 0.750 inches (19.05mm), an outer diameter of 1.225 inches (31.12mm), and a length of 0.394 inches (10.00mm). It is classified as a cable ferrite filter, operates within standard environmental compliance standards including RoHS3, and is currently in active production.

Feature Summary

• Solid construction designed for free-hanging installation on cables
• Utilizes Material 28 for effective high-frequency noise suppression
• Circular geometry accommodates large diameter conductors

Applications

• Suppression of electromagnetic interference on power cables
• Filtering conducted emissions in industrial equipment wiring
• Noise reduction on communication lines requiring large bore cores

Procurement Notes

Verify the specific material grade and impedance tolerance against the official datasheet before integration. Confirm that the inner diameter meets the physical requirements of the target cable assembly. Ensure compliance with relevant regional regulatory standards such as RoHS3 for the intended market deployment.

Selection Notes

Select this component when the application requires filtering for cables with diameters up to 19.05mm. The solid design provides mechanical stability without split halves. Consider the 110 Ohm impedance characteristic at 100MHz to ensure compatibility with the targeted noise frequency spectrum of the system.
