ROTARY CARBON POTENTIOMETER PR-18 series Characteristic PR-18 single turn potentiometers are enclosed in a metal housing, with carbon resistive element. Potentiometers have a linear characteristic of regulation, and are made in one of three versions, which differ in the type of terminals, for PCB and wire soldering. PR-18 series potentiometers may be equipped in a single-pole switch. Potentiometers with 5% and 10% resistance tolerance are available on request. Parameter Value Nominal resistance E3 series Range of available resistances 120 4,7 M R 220 k 20% Resistance tolerance R > 220 k 30% Max. dissipation power Pn (T = 40C) 0,2 W Max. load at category temperature 25% Pn Max. operating voltage 200 V Breakdown voltage 280 V Mechanical rotation angle 300 5 AC 120 V / 1 A Switch parameters DC 16 V / 1 A Climatic category 25/070/10 Shaft types Type Length L mm P1 16 20 25 32 P5 16 20 25 32 P6 16 20 25 32 TELPOD S.A.
