DERATING
The power that the resistor can dissipate depends on the operating temperature.
Maximum dissipation (P
max.
) in percentage of rated power as a function of the ambient temperature (T
amb
)
FUSING CHARACTERISTICS
The resistors will fuse without the risk of fire and within an indicated range of overload. Fusing means that the resistive value of
the resistor increases at least 100 times.
The fusing characteristic is measured under constant voltage.
NFR25 This graph is based on measured data
which may deviate according to the application.
