Power Rating Notes -
The PFS35 Series Resistors must be attached to a suitable
heatsink. The maximum internal resistor temperature is 175°C.
To specify an appropriate heatsink use the following formula :
RHH
=
TMAX - (P * RHR) - TA
P
Where: RqH = Thermal Resistance of Heatsink ( K/W )
RqR = Thermal Resistance of Resistor ( K/W )
TMAX = Maximum Temperature of Resistor
TA = Ambient Temperature of Heatsink ( °C )
P = Power Through Resistor ( W )

Pulse width (seconds)
Tenative continuous-pulse allowance at duty 0.01. Load life test will be necessary
in actual equipment, because curve may be changed by resistance, repetition, duty
and perating temperature.
