【经验】射频电感产生极性的原因和确定极性的方法

2021-01-08 顺络
射频电感,UHQ0402H,HQ0402Q,HQ0402H 射频电感,UHQ0402H,HQ0402Q,HQ0402H 射频电感,UHQ0402H,HQ0402Q,HQ0402H 射频电感,UHQ0402H,HQ0402Q,HQ0402H

在常识里,作为基础元器件的电感是两端无源元件,一端输入,另一端输出,使用时是没有极性的,也就是说正接和反接是没有区别的。


可是,越来越多的工程师反馈,之前用到电感的时候都是随便焊接,没有考虑方向,从来没出过问题;最近测试射频的时候发现有些电感不同的焊接方向对射频指标影响很大,后来分析原因时才注意到电感表面标明了极性。

<射频电感产生极性的原因>

对于同一个电感,测试时摆放的方向不同时,测得的电感量不完全相同,这种现象即被称为电感的极性:

原因:当按照不同的方式摆放时,电感的线圈电极与地的位置状态存在差异,导致线圈与地之间的电容不同,使电感表现出来的电感量存在差异。

在工作频率不太高的情况下,射频电感不同的摆放方向对电感量几乎没有影响,传统上认为这样的电感是没有极性的,外观如下图:

随着4G通讯的普及和5G通讯时代的到来,射频线路工作频率更高,射频电感不同的摆放方向对电感量影响明显,极性问题被重视,这些电感上都会标注极性,外观如下图:

顺络电子新型高Q值射频电感UHQ0402H系列、HQ0402Q系列、HQ0402H系列、HQ0603Q系列、HQ0603H系列、HQ1005Q系列、HQ1005H系列,采用L型电极,本身就是只有一个面可以贴装到PCB板的防呆设计,完美避免了贴片时出现错误的可能,两侧的黑块Mark是用于产线在电感成品装入料盘的料仓时,自动化设备识别保证不带黑块Mark的空白面朝上,从而确保焊盘朝下的:
