目前彩色电视机中的电感线圈,多数使用铁氧体磁芯并用漆包线绕制,外表涂复环氧树脂。由于其外型不同,型号很多,下面只列出常用的SP型电感线圈,外形如图1所示。标记方法:电感量的标记方法也是用三位数表示,与电阻的表示法相似。第一位、第二位为有效数字,第三位表示在第一位、第二位数之后加“0”的个数,小数点用R表示,最后一位英文字母表示误差范围。电性能:标称电感及参数如表1所示。误差范围:J(±5％)、K(±10％)、M(±20％)。额定电流:
The current color TV inductors, the majority of the use of ferrite core and enameled wire wound, the appearance of coated epoxy resin. Because of its different appearance, many models, the following list only the commonly used SP-type inductor coil, the shape shown in Figure 1. Marking method: The method of marking the inductance is also expressed in three digits, similar to the representation of resistance. The first, the second is a valid number, the third said in the first, the second digit after the number of “0”, the decimal point with R said that the last English letter that the error range. Electrical properties: Nominal inductance and parameters shown in Table 1. Error range: J (± 5%), K (± 10%), M (± 20%). Rated current:
