Material Option:
-
Wire Options: Flat Cooper Wire; Flat Aluminum Wire
-
Installation Type: Vertical design, Horizontal Design
-
Core Options: Powder Cores
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).

Compared the classic EI,EE,C foil inductors, Toroidal cores replacement comes more and more popular, because of:
A). LOWER PARASITIC CAPACITANCE
B). SAFER MANUFACTURING PROCESS
C) . DM NOISE POLLUTION REDUCTION & LOWER EMI ELECTROMAGNETIC INTERFERENCE
D) .LEAKAGE FLUX
Main Application:
New patterns of power consumption and generation are reshaping the way electricity distribution networks are used.
Flat Wire Toroidal Inductors are widely used as Booster Inductor & Inverter Inductor, which popular application in:
-
New energy automobile
-
Charging Pile
-
Uninterruptable power supplies (UPS)
-
PV Inverter
