Charakterystyka: The PR 16... single-turn, housed in a metal case, rotary carbon control potentiometers. It comprises a carbon resistive track fitted on a resin modified paper base. Base diameter of potentiometers is 16 mm. Resistance track can be linear-A, logarithmic-B, inverse logarithmic-C or type of M+N. Potentiometers are made single or tandem, either with or without tap, plastic or metallic spindle. Terminals are designed for a PCB or soldering pins. Potenctiometers can be fit out on device hold up spindle in precise location 1, 11, or 41 position. Application: Potentiometers are widely used in electronic audio-video, electric domestic equipment and outer control elements.
