美國BOURNS電位器也叫邦士電位器，伯恩斯電位器，玻璃釉精密可調電位器，可以用螺絲刀一直旋轉，顏色一般是藍色，有三個腳，常用型號有3296,3362,3386,3006,3266,3323,3329,3590,3314,3313,3324等。
有單圈和多圈電位器之分：
單圈：是以一圈的轉動行程，來完成最小至最大的阻值變化；
BOURNS 3296W多圈電位器
多圈，是以超過一圈的旅轉行程完成最小至最大的阻值變化。　　　
調節形式：頂調，側調，正面調和背面調?！　　?br /> 應用領域：主要用于工業控制，通訊設備，精密儀器儀表，汽車電子，液晶面板，開關電源等領域　
-ESD保護IC系列
靜電保護IC用于吸收電路中產生的靜電，從而保護重要元器件； ESD保護IC的應用范圍非常廣泛，只要是電路板都需要類似的靜電 保護元件，最常見于USB接口附近
-電位器系列 又稱可調電阻，通過調節電阻從而達到調速、調壓、調頻的目的；
可調電阻的靈敏度直接決定了終端產品調節部分的精度，因此
可調電阻已經成為電路中一個至關重要的電子元件。
-貼片保險絲系列
功能：過熱保護，過電流保護
優點：粘著于電路板表面的安裝方式可大大節省空間
