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:
Resistor С2-33Н - 1,0 - 220 kOhm ± 5% - А - Д - В - И ОЖ0.467.093 ТУ
