Iron Powder Toroidal Choke Coil

Features
We specialize in manufacturing Iron Powder Toroid Choke Coil, featuring its high quality and competitive price.

  • The GRT series coils are made from iron power provide high performance, compact size, and low cost. High current. Lowest EMI
  • These products have high saturation magnetic-flux density and excellent DC superposition characteristics.
  • Theses products have low leakage and acoustic noise is minimal
There are different kinds of Toroidal Choke CoilWhen you are looking for the right Toroidal Choke, please kindly let us know the request characteristic, include dimension, DCR, saturate current...etc. We will provide most suitable toroidal inductor to you in the shortest time.

G-CHEN also provide Iron Powder Toroidal Choke Coil samples for customer evaluation.
