Please note that, on request, all tappings can be adjusted by Vishay Sfernice. For adjustment purposes we would need to be advised of the ohmic values, and tolerances of the sections in successive order in addition to their sum Rn. The permissible maximum value for an adjustment should take into account the possible negative tolerance of Rn. Please consult Vishay Sfernice regarding the acceptable tolerance. RECOMMENDATIONS FOR USE Maximum Current Strength: The ohmic value and the power decrease as the connections are brought together. To avoid overload, the maximum current strength that is permissible for Rn should never be exceeded: Imax. = P r R n POWER RATING TEMPERATURE RISE 80 60 40 0 0 100 200 300 400 300 200 100 0 450 D8 x3 4 SD 10 x5 RS 0 SD 13 x RS 70 SD 1 RS 6 x 9 SD 4 20 RS x1 SD 17 RS 2 SD 5 x 13 2 5 8 RS SD x 16 8 30 x RS 25 SD 0 40 RS x SD 37 0 50 x3 73 400 RS S RATED POWER IN % 100 RS HOT SPOT TEMPERATURE IN C 120 AMBIENT TEMPERATURE IN C 10 100 1000 RATED POWER IN W MARKING Vishay Sfernice trademark, model, style, nominal resistance (in ), tolerance (in %), manufacturing date.
