Description:
A trimmer potentiometer is a kind of carbon potentiometer. It is an electronic component classified as variable resistor, which is designed to be infrequently adjusted. Usually just at the point of manufacture or when the unit is being recalibrated. Carbon Potentiometer is used as voltage divider to provide variable output voltage. Carbon Potentiometers uses carbon as resistive element. There are also different types of Potentiometers like Wire Wound type and ceramic type using different materials on resistive element. Carbon Potentiometer can be classified into logarithmic type and linear type depending on the mode of operations. Carbon Potentiometers are of many types and sizes depending on resistance value, power rating and type of mounting.
Application:
Trimmer potentiometer is a small potentiometer which is used for adjustment, tuning and calibration in circuits.
