Silicon Steel Core Toroidal Core

Silicon Steel Core Toroidal Core Product Description

---

 

Range of dimension:

- Strip width: minimum 3mm
- Inside diameter: minimum 5mm
- Outside diameter: minimum 8mm, maximum 1100mm

 

Material:

High-quality CRGO steels with the characteristics of low iron-loss and high permeability in thickness of 0.05mm, 0.23mm, 0.27mm, and 0.3mm.

 

Silicon Steel Core Toroidal Core Characteristic:

It is toroidal and wound in the same direction of closed flux path. No magnetic flux leakage. It has the best magnetic performance. It is easy and high-efficiency for coil winding with the toroidal winding machine.
