FUNCTIONAL DESCRIPTION
OPERATING TEMPERATURE RANGE
High Temperature Range Type:
-65°C to +275°C (Fig. 4-1)
Normal Temperature Range Type:
-65°C to +170°C (Fig. 4-2)
POWER RATING
Standard rated power at 70°C:
PU3921 = 3W/5W/9W
PU5931 = 5W/7W/10W
For detail power value, please refer to Table 2.
RATED VOLTAGE
The DC or AC (rms) continuous working voltage
corresponding to the rated power is determined by
the following formula:
V=
Fig. 4-1
Maximum dissipation (P
max
) in percentage of rated
power as a function of the operating ambient
temperature (T
amb
)
(PxR )
Where
V = Continuous rated DC or
AC (rms) working voltage (V)
P = Rated power (W )
R = Resistance value (Ω )
