Common Mode High Current Manganese Zinc Toroidal Inductors

After the loop inductance of a ferromagnetic material sample is magnetized by an alternating magnetic field, different dynamic hysteresis loops can be obtained by changing the magnitude (amplitude) of the alternating magnetic field at the same frequency, and the vertex line of the dynamic hysteresis loop is called the dynamic magnetization curve. DC hysteresis loops were introduced in the previous section for similar types of low frequency and AC hysteresis loops. However, as the frequency increases, the hysteresis return becomes wider due to the loss of the original core, which is different from the DC hysteresis return during this time. Therefore, the dynamic magnetization curve is also different from the static magnetization curve.

The manganese-zinc (mn-zn) ferrite material for ring inductors produced by inductor manufacturers uses a newly developed powder batching technology and heat treatment technology. The core loss is reduced by more than 15% and the saturation flux density is increased by 20% in a high temperature environment of 140°C, which can suppress the power consumption and heat generation environment of power supply circuits in various applications. Curie temperature is 250 degrees.
