Description
CN15
15 mm CERMET PRESET
POTENTIOMETERS
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.
