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:
(1)
ΔT
P = ------------------------------------------------------------------------------------------R TH (j - c) + R TH (c - h) + R TH (h - a)
P:
expressed in W
ΔT:
difference between maximum working temperature and room temperature or fluid cooling temperature
RTH (j - c): thermal resistance value measured between resistive layer and outer side of the resistor. It is the thermal resistance
of the component: 4.28 °C/W.
RTH (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.
RTH (h - a): thermal resistance of the board.
Example:
RTH (c - h) + RTH (h - a) for D2TO35 power rating 3.5 W at ambient temperature +25 °C.
Thermal resistance RTH (j - c): 4.28 °C/W
Considering equation (1) we have:
ΔT = 175 °C - 25 °C = 150 °C
RTH (j - c) + RTH (c - h) + RTH (h - a) = ΔT/P = 150/3.5 = 42.8 °C/W
RTH (c - h) + RTH (h - a) = 42.8 °C/W - 4.28 °C/W = 38.52 °C/W
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.
The formula used to calculate E is:
2
U- x t
E = P x t = ------R
with:
E (J): pulse energy
P (W): pulse power
t (s):
pulse duration
U (V): pulse voltage
R (Ω): resistor
The energy calculated must be less: than that allowed by the graph.
