8 THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENTARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT VALUE AND TOLERANCET hese thermistors have a narrow tolerance on the B-value, the result of which provides a very small tolerance on the nominal resistance value over a wide temperature range. For this reason the usual graphs of R = f(T) are replaced by Resistance Values at Intermediate Temperatures Tables, together with a formula to calculate the characteristics with a high TO DETERMINE NOMINAL RESISTANCE VALUESThe resistance values at intermediate temperatures, or the operating temperature values, can be calculated using the following interpolation laws (extended Steinhart and Hart ):where:A, B, C, D, A1, B1, C1 and D1 are constant values depending on the material concerned; see table is the resistance value at a reference temperature (in this event 25 C, Rref.)

9 = R25).T is the temperature in K. T ( C) = T (K) - numbered and are interchangeable with an error of max. C in the range 25 C to 125 C and max. C in the range -40 C to +25 OF THE RESISTANCE/TEMPERATURE DEVIATION FROM NOMINAL VALUEThe total resistance deviation is obtained by combining the R25-tolerance and the resistance deviation due to B-tolerance .When:X = R25-toleranceY = resistance deviation due to B-toleranceZ = complete resistance deviation, then: or Z X + YWhen:TCR = temperature coefficient T = temperature deviation,then: The temperature tolerances are plotted in the graphs on the previous : at 0 C, assume X = 5 %, Y = % and TCR = %/K (see table ), then.
