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 power inductor is an inductor with a large current passing through it, comparing traditional inductor, it’s with small size, high Q value, low impedance, high efficiency, low temperature rise, customized. When design the power inductors, engineer pay attention to optimizing the click structure, to guarantee the internal magnetic field of products becomes more uniform, and the power inductors w...

With the development of the global economy, the importance of effectively utilizing energy, reducing environmental pollution and preventing environmental emergencies has become increasingly prominent. Protecting the environment is not only related to the living environment of all human beings, but also affects the development of the global economy. 7 countries announce ban on sale of petrol and di...

PFC inductors are widely used in switching power supplies because they improve power factor, power efficiency, electromagnetic interference, and greatly enhance circuit stability.   The working principle of PFC inductor is that when the current passes through it, the magnetic field generated will reduce the rate of change of the current, thereby reducing high-order harmonics in the circuit, s...

For the transformer and inductors, we always test Q value. While, what's Q value?What factors are it related to? Q value, as know as  quality factor, its basic meaning refers to the ratio of inductance to loss pressented by a transformer (inductor) when operating at a certain frequency of AC voltage, it is an important parameter for measuring the transformers and inductors. The higher Q value...

To achieve good performance, when making the magnetic ring inductors, it's crucial to follow standard process design specifications. In terms of design we should notice: 1. To ensure a stable inductance, we should avoid use 15K high conductivity magnetic cores. 2. For amorphous nanocrystalline cores, request plastic case, thus core damage of external forces could be reduced during core winding. 3....
