46 Material 

Our latest material development is a MgZn ferrite intended for suppression applications. This material does not use nickel in its composition, hence it avoids potential environmental issues as well as reduces the cost of the material component of suppression parts. The suppression performance of the 46 material is similar to our widely used 43 material.

The new grade 46 is supplied in the larger sizes of the round cable EMI suppression and snap-it cores.
