该系列产品采用厚膜碳塑阻值，防尘密封结构聚酯材料，在DVD/VCD、功放机、微波炉、家电控制器、音响开关、音量开关、功率放大器等电子产品上应用广泛。

       用于分压的可变电阻器。在裸露的电阻体上，紧压着一至两个可移金属触点。触点位置确定电阻体任一端与触点间的阻值。按材料分线绕、炭膜、实芯式电位器；按输出与输入电压比与旋转角度的关系分直线式电位器(呈线性关系)、函数电位器(呈曲线关系)。主要参数为阻值、容差、额定功率。广泛用于电子设备，在音响和接收机中作音量控制用。
       The series of products using thick film performace of resistance, dustproof sealing structure of polyester material, in DVD/VCD, amplifier machine, microwave oven, home appliances controller, audio switch, volume switch, power amplifier and other electronic products are widely applied.For the partial pressure of the variable resistor. In the bare resistance body, pressed with one or two movable metal contact. Contact position determining resistance body and contacts at either end of the resistance between the. According to material distribution around, carbon membrane, solid core type potentiometer; according to the input and output ratio and rotation angle relation of linear potentiometer ( linear ), function ( a curve ). The main parameters for the resistance, tolerance, rated power. Widely used in electronic equipment, audio and a receiver for volume control.
