2643806402 Description

Short technical summary and product information.

The Fair-Rite 2643806402 is a solid round cable ferrite core designed for EMI suppression in cable applications. It is constructed from Fair-Rite's 43 material, a NiZn ferrite optimized for suppressing conducted interference from 20 MHz to 250 MHz.

 

This core offers a typical impedance of 90 Ohms at 100 MHz, with minimum impedance guaranteed at key test frequencies. The material exhibits an initial permeability of 800 and a Curie temperature greater than 130°C, ensuring stable performance under elevated temperatures.

 

Mechanically, the core has an outer diameter of 25.4mm, an inner diameter of 15.49mm, and a length of 12.7mm, weighing 19.4 grams. Its solid design and free-hanging mounting type allow it to be easily installed over cables for common-mode filtering.

 

This suppression core is suitable for a wide range of electronic equipment requiring EMI control, including power supplies, telecommunications, and industrial systems. It is RoHS3 and REACH compliant.
