Φ17mm Single Turn Carbon Film Rotary Potentiometer With Switch RV17-K2
Application:
Ideal for lighting adjustment, white goods, automobile etc.
Description:
A potentiometer is a manually adjustable variable resistor with 3 terminals. Two terminals are connected to both ends of a resistive element, and the third terminal connects to a sliding contact, called a wiper, moving over the resistive element. The position of the wiper determines the output voltage of the potentiometer. The potentiometer essentially functions as a variable voltage divider. The resistive element can be seen as two resistors in series(potentiometer resistance), where the wiper position determines the resistance ratio of the first resistor to the second resistor.

Materials used for potentiometer:
| Material | Properties |
| Carbon composition | Carbon composition ink molded on a substrate(phenolic resin). Most common material, low cost and reasonable noise and wear characteristics. |
| Wirewound | Wirewound pots can handle high power,are long lasting and can be very precise. They have however a limited resolution and rough feel. Most used in high power applications (rheostats are often wirewound) or as precision pots. |
| Conductive plastic | Very smooth feel and high resolution, can be constructed to perform millions of cycles. Can only handle a limited power and are expensive. Often used in high-end (audio) equipment where a high resolution and low noise are important. |
| Cermet | Very stable, low temperature coefficient and handles high temperatures well. On the other hand quite expensive and often limited amount of cylces allowed(special long-life cermet pots also exist). Often used for trimpots which do not have to be adjusted often. |
