The quality factor of inductance coil Q
因数Q是表示线圈质量的一个重要参数。Q值的大小，表明电感线圈损耗的大小，其Q值越大，线圈的损耗越小;反之，其损耗越大。
Factor Q is an important parameter indicating the quality of the coil. The size of the Q value indicates that the larger the Q value of the inductance coil is, the smaller the loss of the coil is, and the larger the loss is.
品质因数Q的定义为:当线圈在某一频率的交流电压下工作时，线圈所呈现的感抗和线圈直流电阻的比值。它可以用公式表达如下:
The quality factor Q is defined as the ratio of inductance to coil DC resistance when the coil operates at AC voltage at a certain frequency. It can be expressed as follows:
电感线圈的品质因素Q及电感特性参数
Quality factor Q and inductance characteristic parameters of inductor
式中：W－－工作角频率 L－－线圈电感量 R－－线圈总耗损电阻
Type: W - working angle frequency L - coil inductance R - coil total loss resistance
根据使用场合的不同，对品质因数Q的要求也不同。对调谐回路中的电感线圈，Q值要求较高，因为Q值越高，回路的损耗就越小，回路的效率就越高;对鹅合线圈来说，Q值可以低一些;而对于低频或高频扼流圈，则可以不做要求。
According to the different use occasions, the requirement of quality factor Q is also different. For the inductance coil in the tuning loop, the Q value is higher, because the higher the Q value, the smaller the loss of the loop and the higher the efficiency of the loop; for the goose coils, the Q value can be lower, and the low frequency or high frequency choke ring can not be required.
江苏春晨YCB扁电缆实际上，Q值的提高往往受到一些因素的限制，如导线的直流电阻、线圈骨架的介质损耗、铁心和屏蔽引起的损耗以及高频工作时的集肤效应等。因此，线圈的Q值不可能做得很高，通常Q值为几十至一百，较高也只有四五百。
In fact, the improvement of the Q value is often limited by some factors, such as the DC resistance of the wire, the dielectric loss of the coil skeleton, the loss caused by the core and shielding, and the skin effect in the high frequency work. Therefore, the Q value of the coil can not be very high, usually Q to tens to one hundred, the highest is only four hundred or five hundred.
电感的主要特性参数
The main characteristic parameters of the inductor
1、电感量L及精度
1, inductance L and precision
电感量L表示线圈本身固有特性，与电流大小无关。除专门的电感线圈（色码电感）外，电感量一般不专门标注在线圈上，而以特定的名称标注。线圈电感量的大小，主要决定于线圈的直径、匝数及有无铁芯等。电感线圈的用途不同，所需的电感量也不同。例如，在高频电路中，线圈的电感量一般为0.1uH—100H。
The inductance L represents the inherent characteristics of the coil itself and has nothing to do with the current size. In addition to the special inductor (color code inductor), inductance is generally not specified on the coil, but is marked by a specific name. The inductance of the coil depends mainly on the diameter of the coil, the number of turns, and whether there is an iron core. The inductance of the inductor is different, and the inductance required is also different. For example, in high frequency circuits, the inductance of the coil is generally 0.1uH - 100H.
电感量的精度，即实际电感量与要求电感量间的误差，对它的要求视用途而定。对振荡线圈要求较高，为0．2-0．5％。对耦合线圈和高频扼流圈要求较低，允许10—15％。对于某些要求电感量精度很高的场合，一般只能在绕制后用仪器测试，通过调节靠近边沿的线匝间距离或线圈中的磁芯位置来实现。江苏春晨YCB扁电缆
The accuracy of inductance, that is, the error between the actual inductance and the required inductance, depends on its application. The demand for the oscillating coil is higher, 0.2-0.5%. The coupling coil and the high frequency choke require less 10 to 15%. For some occasions where the precision of inductance is very high, it is usually only tested by instrument after winding, and is realized by adjusting the interturn distance between the lines near the edge or the position of the core in the coil.
2、感抗XL
2, reactance XL
电感线圈对交流电流阻碍作用的大小称感抗XL，单位是欧姆。它与电感量L和交流电频率f的关系为XL=2πfL
The size of the inductance coil's impediment to alternating current is called XL, which is ohmic. It is related to the inductance L and the alternating current frequency f as XL=2 PI fL.
