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...

Toroidal transformer are popular application in different field, here let’s discuss details more: Q1: If the toroidal isolation transformer could play as a filtering? A: Can't. The function of transformer is to convert the voltage & the AC current, it can't play as a filtering. Generally, when a transformer is rectified, an electrolytic capacitor will be added to form a rectification filter pa...

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 ...

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...
