atransformer by iron core (or core) and the coil, coil composed two or more electrical windings, which is called primary coil winding circle of power supply, and the rest of the electrical windings called secondary coil. 变压器由铁芯 (或核心) 和卷,卷组成了两个或多个电子绕,称一次线圈电源绕...
The differences in characteristics among parts or the fluctuations of the inductance value of a coil due to temperature variation is lessened by reducing the stray capacitance components induced among the layers of wound conductor, and size reduction and cost reduction are achieved. A winding portion...
