Single phase Jencores in GOSS

Although Jencores can be made in any size, we have designed a standard range of Jencores to suit existing E and I Lamination bobbins and frames.

Single phase Jencores in NOSS

It is possible to manufacture Jencores from non-grain oriented silicon steels for applications where superior magnetic properties are not required e.g. welding transformers. In these cases, the use of NOSS in Jencores affords competitive prices to lamination packages, while offering savings in handling and assembly time and improved electric performance. These JH Cores have been designed to suit bobbins used in laminations. The construction used in these Jencores is DUO and 0.35mm NOSS is the preferred material used. Shell or Core type Jencores are available.
