Custom inductors, power Yu Electronics (certified), Songshan Lake inductors

 In the selection and use of inductors, we must first think to check the measurement of the coil, the coil and then to judge the quality is good or bad, and the pros and cons. For accurate detection of the inductor coil inductance and quality factor Q, generally require specialized equipment, and the test method is more complex. In practice, this is generally not detected, only the on-off checks performed and the Q value of the coil size determination. Can first use a multimeter to measure the resistance profile of the coil DC resistance, and then determine the resistance or the original nominal resistance compared to the resistance if the measured resistance value than the original, or to determine the nominal resistance increases a lot, even the pointer does not move (resistance tends to infinity X) can be judged coil disconnected; if the measured resistance is very small, it is determined that a serious short circuit or partial short circuit is difficult to compare them. These two conditions, it can be determined the coil is bad, can not be used. If the sense resistor and the original nominal resistance identified or less, can determine this coil is good. In this case, we can according to the following situations inductance coil around the law, to determine the size of the quality of the coil that Q values. Inductance of the coil is the same, the DC resistance, the higher the Q value; the larger the diameter of the wire, the greater the Q value; when the use of a multi-strand wire wound, the greater the number of lead wires custom inductor, The higher the Q; loss bobbin (or core) of the material used, the higher the Q value. For example, when doing high silicon steel sheet iron core inductor, its Q value compared with ordinary silicon steel core made of high; coil distributed capacitance and leakage flux, the higher its Q value. Refers to a set of winding inductance coil having a predetermined function of the basic components of local inductor winding single-layer and multi-points, the magnet core and the magnet core and the general use of nickel-zinc ferrite or Mn-Zn ferrite and other materials, the "workers" shaped, cylindrical, cap, a variety of shapes "E" shape, pot shape. Inductor core material mainly common sense silicon, permalloy, its shape more for "E" type. Some magnetic shield to prevent the inductor at work and the impact of other circuit components to work properly, it increases its metal screen cover. Using the shield inductor coil will increase the wear and tear, so that the Q value decreases. Some information package inductor (eg color code inductors, color ring inductors, etc.) around the system is completed, with the coil and core package of information, such as sealed.
