311915-121N-1.4型(Type 311915-121N-1.4)参考形状与尺寸（单位mm）
Outline Dimensions (Unit: mm)
*电感量数码表示法举例说明: 121 表示 12 后面 1个 0，电感量为 120μH。
*Inductance Coding Example: The code "121" denotes 12 times 10, which equals 120μH.311915-121N-1.4 电气特性参数(Electrical Characteristics)
阻抗特性参考曲线图(Reference Impedance Characteristic Curves)
*共模电感相同磁导率磁芯相同圈数使用不同线径，使得绕线方式或层数不相同，阻抗特性也会不同。
*Variations in wire diameter, winding techniques, or layer counts will affect the impedance characteristics, even with identical cores and turn counts.
*不同磁芯厂家相同磁导率磁芯其频率特性也会有差异。
*Frequency response may differ across manufacturers, despite having the same nominal permeability.
