Product Description
This kind of 3386 Trimming Potentiometer has three terminals, and the resistance can be adjusted according to a certain change rule. It usually consists of a resistor and a movable brush. When the brush moves along the resistor body, a resistance value or voltage which is in a certain relationship with the displacement amount is obtained at the output end. When a voltage is applied between the two fixed contacts of the resistor body, the position of the contact on the resistor body is changed by a rotating or sliding system, and a voltage with certain relationship with the position of the movable contact is obtained between the movable contact and the fixed contact. Thus the 3386 Trimming Potentiometer is usually used as a voltage divider. It also has the advantages of high quality, sophisticated design, compact structure, high quality, durability as well as high cost effective. The 3386 Trimming Potentiometer wins a good reputation among clients due to excellent performance.
