电感器的主要参数:
a.标称电感量:
[1]上标注的电感量的大小.表示线圈本身固有特性,主要取决于线圈的圈数,结构及绕制方法等,与电流大小无关,反映电感线圈存储磁场能的能力,也反映电感器通过变化电流时产生感应电动势的能力.单位为亨(H).
b.允许误差
:
电感的实际电感量相对于标称值的允许偏差范围称为允许误差.
c.感抗
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.
d.品质因素 Q
:
表示线圈质量的一个物理量,Q为感抗XL与其等效的电阻的比值,即：Q=XL/R.
线圈的Q值愈高,回路的损耗愈小.线圈的Q值与导线的直流电阻,骨架的介质损耗,屏蔽罩或铁芯引起的损耗,高频趋肤效应的影响等因素有关.线圈的Q值通常为几十到一百.e.额定电流:额定电流是指能保证电路正常工作的工作电流.f.标称电压g.分布电容（寄生电容）
4.感量和误差的标注方法:
a.直标法:
在电感线圈的外壳上直接用数字和文字标出电感线圈的电感量,允许误差及工作电流等主要参数.
b.色标法：同电阻标法.单位为μH

供应松下电感ELJ-SA100KFN
信息内容：电感器结构特点 （一）电感器的结构与特点电感器一般由骨架、绕组、屏蔽罩、封装材料、磁心或铁心等组成。 1．骨架 骨架泛指绕制线圈的支架。一些体积较大的固定式电感器或可调式电感器（如振荡线圈、阻流圈等），大多数是将漆包线（或纱包线）环绕在骨架上，再将磁心或铜心、铁心等装入骨架的内腔，以提高其电感量。骨架通常是采用塑料、胶木、陶瓷制成，根据实际需要可以制成不同的形状。小型电感器（例如色码电感器）一般不使用骨架，而是直接将漆包线绕在磁心上。 空心电感器（也称脱胎线圈或空心线圈，多用于高频电路中）不用磁心、骨架和屏蔽罩等，而是先在模具上绕好后再脱去模具，并将线圈各圈之间拉开一定距离。 2．绕组 绕组是指具有规定功能的一组线圈，它是电感器的基本组成部分。 绕组有单层和多层之分。单层绕组又有密绕（绕制时导线一圈挨一圈）和间绕（绕制时每圈导线之间均隔一定的距离）两种形式；多层绕组有分层平绕、乱绕、蜂房式绕法等多种。 3．磁心与磁棒 磁心与磁棒一般采用镍锌铁氧体（NX系列）或锰锌铁氧体（MX系列）等材料，它有“工”字形、柱形、帽形、“E”形、罐形等多种形状。 4．铁心 铁心材料主要有硅钢片、坡莫合...
