FUNCTIONAL DESCRIPTION
OPERATING TEMPERATURE RANGE
Range: –55 °C to +155 °C
POWER RATING
Each type rated power at 70 °C:
SR0805 = 1/8 W (0.125W)
SR1206 = 1/4 W (0.25W)
SR1218 = 1 W
SR2010 = 3/4W (0.75W)
SR2512 = 1 W
RATED VOLTAGE
The DC or AC (rms) continuous working voltage
corresponding to the rated power is determined by
the following formula:

as a function of the operating ambient temperature (T_amb)
V = √(P X R)
Where
V = Continuous rated DC or AC (rms) working voltage (V)
P = Rated power (W)
R = Resistance value (X)
