We all know that each inductor has a number of corresponding sensed values, but how do we measure the sense value? What are the matters to be paid attention to in the process of measurement? Now let's make a summary of the science and technology.
1. The inductor element, whose core and winding are easily changed by the effect of temperature rise, should be noticed that the body temperature must be in the scope of use.
2, the winding of the inductor is easy to form the electromagnetic field after the current passes through. In the element positions, should pay attention to the face of the inductor winding away from each other, or at right angles to each other, in order to reduce the amount of mutual induction.
3, the inductor's windings, especially the multi circle fine wires, will also produce the gap electrical capacity, which will cause high-frequency signal bypass and reduce the actual filter effect of inductors.
4. When measuring the inductance and Q value of the instrument, in order to get the correct data, the test lead should be as close to the element body as possible.
