This is a high-performance nanocrystalline core. The magnetic core is made of 1K107 nano-crystalline strip produced by our company. This magnetic core has characteristics such as high magnetic permeability, low loss, and high saturation. It is the preferred solution for applications such as common mode inductors and current transformers. nano-crystalline magnetic cores have higher impedance at high frequencies. Thanks to the high magnetic permeability of nano-crystals, the size and weight of common mode inductors and current transformers can be further reduced. It can carry higher currents and is not prone to current imbalance and performance degradation at high temperatures.
