ELECTRICAL CHARACTERISTICS
DERATING
The power that the resistor can dissipate depends on the operating temperature.
Fig. 2. Maximum dissipation (Pmax) in percentage of rated power as a function of ambient temperature (Tamb)
APPLICATION INFORMATION
Hot spot
Solder spot
Fig. 3.
φ 0.58 mm Cu – leads
Hot spot temperature rise (
∆T) as a function
of dissipated power
