Acceptable dissipation power of  resistors (Pt) in the operating temperature range from – 60ºC to 155ºC  at the standard atmosphere pressure   is shown in   Figure 1


Fig.1

 

I – for resistors C2 – 33H (besides resistors C2-33H – 0,125 with resistance more than 3,01×106 Ohm)

II – for resistors C2-33H-0,125 with resistance more than 3,01×106 Ohm

Acceptable dissipation power of  resistors (Pp) in the operating  pressure range from 10-6 mm of mercury column to 3 kgf/sm2  in the temperature range from 60ºс to 155ºC   is shown in  figure 2


Fig.2

Conventional symbol of resistors when ordering and in the  construction documentation of other production must contain the word “ Resistor”, contracted notation of a type, complete value of rated resistance and tolerance limits, level of  noise index (only for group “А” and  “Б”), TCR  index, all climate  index “В”, letter “И” for resistors with higher stability to impulsed load  and  TR  index for example:
