Main characteristic parameters of inductance

Main characteristic parameters of inductance

The quality factor Q is a physical quantity representing the quality of the coil, and Q is the ratio of the inductive reactance XL to its equivalent resistance, I .e., Q = XL/R. The higher the Q value of the coil, the smaller the loss of the loop. The Q value of the coil is related to the DC resistance of the wire, the dielectric loss of the skeleton, the loss caused by the shield or the iron core, and the influence of the high frequency skin effect. The Q value of the coil is usually several tens to several hundreds. The use of magnetic core coils, multi-strand thick coils can improve the Q value of the coil.

Common Inductance Coil

Common Inductance Coil

If the coil is wound, its plane is not parallel to the plane of rotation, but intersects at a certain angle, this coil is called a honeycomb coil. And its rotation, the number of times the wire bends back and forth, often called the fold number. The advantages of the honeycomb winding method are small size, small distributed capacitance and large inductance. Beehive coils are wound using a beehive winding machine. The more folding points, the smaller the distributed capacitance.

The connection and difference between inductance and magnetic beads

The connection and difference between inductance and magnetic beads

The size of the magnetic beads (to be exact, the characteristic curve of the magnetic beads) depends on the frequency of the interference wave that needs to be absorbed by the magnetic beads. Magnetic beads are high frequency resistance, low DC resistance, high frequency resistance. For example, 1000R @ 100Mhz means that there is a resistance of 1000 ohms for signals with a frequency of 100M. Because the unit of a magnetic bead is nominal according to the impedance it generates at a certain frequency, the unit of impedance is also ohms. The datasheet of magnetic beads is usually accompanied by a characteristic curve of frequency and impedance. Generally, 100MHz is taken as the standard, such as 2012B601, which means that the Impedance of magnetic beads is 600 ohms at 100MHz.

What is an inductor

What is an inductor

An inductor (Inductor) is an element that converts electrical energy into magnetic energy and stores it. The structure of an inductor is similar to a transformer, but with only one winding. An inductor has a certain inductance, which only hinders the change of current. If the inductor is in a state where no current is passing through, it will try to prevent current from flowing through it when the circuit is turned on; if the inductor is in a state where current is passing through, it will try to maintain the current when the circuit is turned off. Inductors are also called chokes, reactors, and dynamic reactors.
