如何测试nH级的电感感量?电感规格书上一般都是写测试频率100MHz,但一般电桥测试频率只有1MHz,而且测试nH级别很不准,不知道电感厂是怎样测试的

可以使用高频阻抗分析仪测量。世强开放实验室可以测量nH级别的插件电感,如有需要可咨询400-887-3266或直接在平台上预约测试。

如何算电感绕多少圈才是我要的感量?

电感量的计算不单纯包括线圈匝数,所以还需要知道材料磁导率,横截面积,绕线长度这些参数。这是空芯多层线圈电感量的近似计算公式:已知线圈的尺寸:D—线圈的平均直径(cm);W—线圈的宽度(cm);H—线圈的厚度(cm),N—线圈的匝数。电感量L(μH)=(0.08×D×D×N×N)÷(3×D+9×W+10×H),如果长度单位用(mm),得到的L单位为(mH)。如果是空芯单层线圈,可按如下近似式计算:L(μH)=(0.01×D×N×N)÷(W÷D+0.44)

变压器电感量,漏感怎么降到最低?

开关电源的变压器,其电感量和漏感并不是越低越好,都需要根据实际参数匹配最佳值,电感量通过磨磁芯就可以降低,在骨架上加挡墙可以降低漏感。

电感可靠性测试方法汇总

杰绅电感分享电感可靠性测试的一些经验内容,希望能够在一定程度上帮到大家。

2024-10-31 -  技术探讨 代理服务 技术支持 采购服务

采用LCR电桥测量毫欧电阻,为什么在测量频率分别是100Hz和10kHz是测得的结果相差很大?

电阻上面都会存在寄生电感的,对于毫欧电阻来讲,使用LCR电桥测试时,不同的测量频率下测得的寄生电感值也会有差别。通常电阻规格书上会标有推荐测量条件下的值,如测量频率1kHz时的典型值。

功率电感如何选型?

所谓功率电感,一般指那些电流较大的电感,除了电感量之外,还要考虑通过电流大小。选择功率电感主要看感值、直流电阻、饱和电流、温升电流、测试频率、尺寸等几个参数。本文中顺络详细为您解析。
