Inductor coil in our daily life and popular, it plays an important role in electronic equipment, but with the inductor coil market mixed up, high quality inductor coil has become more and more difficult to find, how to judge the quality of inductor coil? The stability of the inductor coil refers to the degree to which the parameters of the inductor coil change with the change of environmental conditions. Usually, the inductor temperature coefficient αL is used to evaluate the stability of the inductor coil, which represents the stability of the inductor quantity relative to the teariness Inductor temperature coefficient is mainly caused by the expansion of inductor coil wire after being heated, resulting in geometric deformation of inductor coil. In order to improve the temperature stability of inductor coil, inductor coil can be made by thermal winding method. The wire wound inductor coil can be connected with current to make the wire hot before winding inductor coil In this way can make the inductance coil cooling shrinkage and clingy on the skeleton, no longer likely to occur after heated deformation, accordingly to improve the stability, in addition to temperature, temperature can also cause the change of the inductance coil parameters, for example, increasing humidity worsened the distributed capacitance of inductance coil and loss increase, reduce the stability of the inductor coil When the inductor coil is in use, if there is no special measuring instrument, the multimeter can be used for simple quality judgment, and the multimeter can be used to measure the DC resistance of the inductor coil, and then compared with the original determined resistance value or nominal resistance value If the measured resistance is infinite, can be concluded that inductance coil break line, if the measured resistance small, can determine the inductance coil has a short circuit layer, the emergence of the two cases, can determine the inductance coil have quality problem, can't use, if detection of resistance and the original determine or nominal resistance were similar, may think that the quality of the inductance coil is basically good Fuying electronic inductor coil has the following advantages: 1 the machine is all full automatic winding machine, equipment repetition accuracy 0.001, peers may not be able to do 2 wire diameter can do 0.012mm. There is no second company in China that can achieve 3. It adopts lean production with one piece flow mode and can detect quality abnormalities in time. 4. Coil raw materials and wire brands are well-known suppliers in the industry, such as Eli Solle, Japan Ohei and Sumitomo, with high quality stability。
