302

      The model 302 is 2" (50.8 mm) single turn wirewound precision potentiometer.
      The model 302 has 4 features.The 1st one is about screw, servo and bushing mount types available.The 2nd one is that the large range of ohmic values is from 5 to 85 k.The 3rd one is about extra taps upon request.The last one is that gangable up to 6 sections on a same shaft.
      The following is about the electrical specifications of model 302.The absolute minimum resistance is linearity x total resistance or 0.5 whichever is greater.The end voltage is linearity x total applied voltage for total resistance above 20 or 2.0 % of total applied voltage for 20 and below.The standard tolerance is within ± 1.0 % and the best practical is within ± 0.50 % for linearity (Independent) 5 to 50 .The standard tolerance is within ± 0.50 % and the best practical is within ± 0.35 % for linearity (Independent) 50 to 200 .The standard tolerance is within ± 0.25 % and the best practical is within ± 0.20 % for linearity (Independent) 200 to 1 k.The standard tolerance is within ± 0.25 % and the best practical is within ± 0.15 % for linearity (Independent) 1 k to 10 k.The standard tolerance is within ± 0.25 % and the best practical is within ± 0.10 % for linearity (Independent) 10 k and above.Noise is 100 ENR.Electrical angle is within 350° ± 2°.Power rating of Section 1 is 40W at 70 ambient derated to zero at 125.Power rating of additional sections is 75 % of the rating of section 1 (3.0 W at 70).Insulation resistance is 1000 M minimum 500 VDC.Dielectric strength is 1000 VRMS at 60 Hz.Taps (Extra) is 21 available as special and standard tolerance within ± 1°.Phasing (CCW End Points) is additional sections phased to section 1 within ± 1°.
