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 we know, the inductance value will influence inductors application, today let’s talk about how to select an inductors based on inductance value. During the inductance is almost not stable during the entire working period of the components,  understand the effective value scope is particularly important. Thus, you should know your power circuit's inductance scope clearly. For inductors in p...

Inductors, which also called reactors. In theory, all electrical conductors which can carry current are inductive, because once an electrical conductor is connected to the power, a magnetic field in a certain space it occupies will be created. As we know, while power supply long, or the electrical conductor's inductance is not large enough, the magnetic field is not strong enough. We called induct...

Comparing Classic EI, EE, C foil inductors, Flat wire toroidal inductors are hot in the market, here let’s discuss why people prefer flat wire, rather than common toroidal wire: Round Wire Limitations Frequencies >20KHz Round wire take best efficiency in frequencies up to 20KHz. In higher frequencies, skin effect (with electrons travelling mainly on the surface area of the conductor instead of ...

The current transformer’s wiring accuracy is very important, because in the secondary circuit, weather the current transformer wiring is appropriate is the basis for weather the secondary circuit appropriate. During power installation engineering projects, the key content is electrical debugging work, especially the secondary circuit inspection, which related to the precise measurement, maintenanc...
