Description
The CN-15 series are manufactured as a thick film resistance track layer on ceramic substrate. The CN-15 preset series potentiometers are linear . The terminals, a and c (see Fig. 1) are the end terminals; b is the central terminal connected to the slider. All terminals are applicable to a PCB.
Applications
These potentiometers are designed for preset resistance control with provision for re- adjustments. They are particularly suitable fore use in professional and/or in those applications where stability is important.
