Toroidal Nanocrystalline Core

Toroidal, or ring type is the most popular shape of nanocrystalline core, which is wound by very thin ribbon. The manufacturing process of such cores is simple, as no toolings or jigs are required during the heat-treatment process. And the toroidal nanocrystalline cores have another advantage, i.e, the leak flux of ring coil is very low. So, it had a wide range of applications, from switch mode power supply (SMPS) to power system. Of course, we can provide special shape nanocrystalline cores, such as rectangular cores, oval cores, split cores, and so on.
