FAQ - 霍尔元件

霍尔元件的等效电路是怎样的?

 [Q0388]

回答

四个电阻的桥接电路。

霍尔元件有极性吗?

 [Q0389]

回答

在霍尔元件目录的外形尺寸图上有记载。

例如HW-101A,在1号引脚上加上+,在3号引脚上加上-的输入,将N极的磁铁靠近封装表面时,2号引脚上+,4号引脚上-输出。如果S极磁铁靠近封装表面时,输出极性相反,2号引脚-,4号引脚+输出。

霍尔元件的引脚镀金是什么?

 [Q0392]

回答

HW-300B和HW-32B有镀银和镀锡。其他都是镀锡。全部都支持RoHS。(2010年5月)

对应无卤素吗?

 [Q0393]

回答

也有对应的等级。详情请咨询。

相对于磁通量密度线性最好的霍尔元件是哪个?

 [Q0394]

回答

HG系列霍尔元件。定电流驱动时,线性在0.5T以下,不到2%。

霍尔元件的特性有滞后现象吗?

 [Q0395]

回答

超高灵敏度型的HW霍尔元件内部有磁性体,因此存在滞回性。
