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...

Q1. What’s the advantage of CRGO core toroidal transformer? The core of toroidal transformer is rolled by high-quality CRGO sheets (thickness <0.35mm), its performance is superior to laminated cores. The coils of toroidal transformer were wound on the core evenly, the direction of magnetic field lines generated by the coils almost completely coincides with the magnetic circuit of the core. Comp...
