Silicon steel sheet is a ferrosilicon soft magnetic alloy with extremely low carbon content, general silicon content is 0.5-4.5%. The addition of silicon increases the resistivity and maximum permeability of iron, and reduces coercivity, core loss (iron loss), and magnetic aging. Silicon Steel mainly used to make cores for various transformers, motors and generators. The performance indicators of ...

In switching power supplies, there are two common types of noise: common mode noise and differential mode noise. The noise with the same path as the input signal is called differential mode noise, while the noise from ground to output with the same phase is called common mode noise. Common mode inductance can suppress common mode noise and improve signal quality through filtering. As for power lin...

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....
