Flat Wire Toroidal Inductor

Powder cores are distributed air gap cores, with excellent inductance stability under both DC &AC conditions, high resistivity, low hysteresis & eddy current losses.


Flat Wire Toroidal Inductor 


For different application request, we suggest different powder core:

1). For lowest loss inductor, the ultra low losses Kool Mμ Hf and MPP Powder cores are goods.

2). For the smallest core size in a DC Bias dominated design, the HIGH FLUX &EDGE powder cores with highest flux capacity are suggested.

3). For competitive cost, but reasonable low core loss & high saturation,Kool Mu powder core is good choice.

4). For low & medium frequency inductors and chokes, high saturation XFlux powder cores are much more economical, high saturation material (1.6T).
