CHOICE OF THE BOARD
The user must choose the board according to the working conditions of the component (power, room temperature). Maximum
working temperature must not exceed 175 °C. The dissipated power is simply calculated by the following ratio:

: Thermal resistance value measured between resistive layer and outer side of the resistor. It is the thermal resistance
of the component: 6.5 °C/W.
R
TH (c - h)
: Thermal resistance value measured between outer side of the resistor and upper side of the board. This is the thermal
resistance of the solder layer.

Single Pulse:
These informations are for a single pulse on a cold resistor at 25 °C (not already used for a dissipation) and for pulses of
100 ms maximum duration.
