Scope
This specification specifies the general requirements, quality assurance regulations, etc. for non wire wound pre adjustable potentiometers This specification applies to non wire wound pre adjustable potentiometers (hereinafter referred to as potentiometers) for screw drive and single turn rotation. The upper limit category temperatures of these potentiometers are 125 ℃ and 150 ℃, respectively. The maximum ambient temperatures for full load operation (at which point the entire resistor body has been connected) are 70 ℃ and 85 ℃, respectively (see Figure 2). The allowable deviation of the resistance value of the potentiometer is ± 10%
