In some cases, this increase is on the order of thousands of times. The shape of the core for inductors, coils and chokes is also significant. Toroidal cores offer more inductance, for a given core ...

Toroidal Toroidal inductors resemble doughnuts and differ in terms of diameter ... Multilayer Multilayer inductors are made by layering the coil between multiple layers of core material. Normally, the ...
