Guangzhou Amorphous Electronic Technology Co.,ltd use soft magnetic materials high permeability nanocrstalline strips for cores and current transformer production. Following information about nanocrystalline alloy: On the basis of the Fe-Si-B alloy composition, extral added with a trace amount of elements Cu, Nb, and prepared the amorphous ribbon by rapid solidification with a cooling rate of abou...
Common Mode Chokes When we said a common mode choke, it means it was wound both line and neutural windings on a single core. Since the noise would be common mode noise usually, the way to lower (if not eliminate) the unwant noise frequencies is to use a common mode choke As below picture show us details of Common-Mode Signals Defined: Such signals can arise from one or more of the following source...

Our nanocrystalline cores for current &voltage transformers are recognized for quality, longevity and adaptability for a number of years. Our nanocrystalline cores supply medium voltage transformer up to 36kV for use in MV or HV applications . Current Transformers Nanocrystalline Cores • Highest System V...
Comparing round copper wire, flat copper wire with more excellent performance, higher current ( unit current density reach 1.5~2.0 times) & smaller volume (0.5~1.0 times). Lower DC resistance, extremely small capacitance distribution, perfect heat dissipation. Closed magnetic circuit design, small magnetic leakage, stable impedance balance, good conducted radiation effect and EMI effect. Autom...
As a expert of soft magnetic core, Coilcore make high frequency nanocrystalline core to replace old ferrite core, which used in inverter, welder machine. What's more, we can copper winding the cores of transformers based on OEM design. We obtain question from customers about the HF Transformers, and feedback professional suggestion like below: Question: Is it permissible to connect 6 transfo...
During EMC power supply circuit design, common-mode interference is the most difficulties encountered, common mode inductor is one of the major methods on solving interference signals. Here let's talk about the basic principles of solving EMC artifacts from design plan in this way. A common mode inductance, is wound both line and neutural windings on a single core. While the magnetic flux in ...
Alloys and the Specification Fe-base nanocrystalline alloy ribbon (mainly composed of Fe,Cu,Nb,Si,B)is very low loss with high permeability. It provides excellent performance for current transformer,EMC/EMI,Invent transformer and so on. General Properties and Characteristics Ribbon Dimensions and Lamination Factor Typical Characteristic Fig.1 1k107 Fig.2 1k107B
