High Power Three Phase Common Mode Inductors

High Power Three Phase Common Mode Inductors

Material: basically for ferrite, of course, this ferrite is also different, generally have MXO- manganese zinc and NXO- nickel zinc class. The main advantage of nickel-zinc class is that its initial permeability is low (less than 1000u), but it can operate at relatively high frequencies (more than 100MHZ) and keep the permeability unchanged. Very strong, very great.

NXO has higher electrical resistivity than MXO. The high frequency clutter is released as thermal energy by the damp-like action of ferrite, which explains the temperature problem of common mode inductors.

Overall Advantages:

The most important point: low cost (someone used this is 0.9 RMB), can be wound by machine, efficient, commonly used UU9.8 or UU10.5;

With a skeleton, the winding process should be better controlled, allowing for higher inductance;

Good pressure and reliability? For common mode of magnetic ring;

Good plug-in, easy to install. Four feet, the hole is right, there is no problem; Basic used in small current power supply, because the wire diameter can not be used very thick, so the current can not be too large;
