2643804502 Description

Short technical summary and product information.

The Fair-Rite 2643804502 is a round cable EMI suppression core designed for filtering conducted electromagnetic interference. This solid core is constructed from Fair-Rite's 43 material, a NiZn ferrite that is popular for suppression applications from 20 MHz to 250 MHz.

 

Key specifications include a typical impedance of 100Ohm at 100MHz and a minimum impedance of 100Ohm at the same frequency. The core has an outer diameter of 31.12mm, an inner diameter of 19.05mm, and a length of 15.93mm. It is a free-hanging component with a weight of 36 grams.

 

The 43 material offers an initial permeability of 800 and a Curie temperature greater than 130°C. This core is burnished to remove sharp edges and is suitable for use in a variety of electronic equipment to suppress cable-borne EMI.
