Flat wire surface area up to 60% more, means at higher frequencies flat wire support better skin effect, better for design higher current solutions, popular in UPS, solar, automotive, industry application.
Material Option:
Powder cores are distributed air gap cores, with excellent inductance stability under both DC &AC conditions, high resistivity, low hysteresis & eddy current losses.
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).
