About the Quality Factor of Inductance

The quality factor of an inductor, commonly known as the Q value, is an important parameter for measuring the performance of an inductor device. It is defined as the ratio of the inductance presented by an inductor when operating at a certain frequency of AC voltage to its equivalent loss resistance.

How to Calculate The Initial Permeability of Soft Ferrite Core Materials

The alternating magnetic field magnetization of ferromagnetic material samples, at the same frequency, changes the magnitude (amplitude) of the alternating magnetic field, and different dynamic hysteresis loops and the vertex connections of the dynamic hysteresis loops can be obtained, which are called dynamic magnetization curves.

Methods for Improving Voltage Withstand of Common Mode Choke in Winding and Material Selection

The use of different wires in the magnetic ring common mode inductor will have different effects on the withstand voltage of the magnetic ring common mode inductor. When two sets of enameled wires are used for the magnetic ring common mode inductor, the thicker the wire diameter, the better the voltage withstand effect.

Application Principle of Clamp Type Ferrite Ring Core

Compared to the two half clamp type magnetic ring, the general magnetic ring is a common anti-interference component in electronic circuits, which has a good suppression effect on high-frequency noise. It is used for electronic devices in daily life, such as display signal cables, USB connection cables, and plastic lumped integrated magnetic rings on data lines.

Six Issues to Pay Attention to When Inductors Selection

What aspects should be considered when selecting inductors? When selecting an inductor, it is necessary to consider whether its performance parameters (inductance, rated current, quality factor, etc.) and external dimensions meet the requirements. When selecting, the following six items should be noted:
