CHOICE OF THE HEATSINK
The user must choose according to the working conditions of the component (power, room temperature).
Maximum working temperature must not exceed 155 °C. The dissipated power is simply calculated by the following ratio:
(1)
ΔT
------------------------------------------------------------
P =
[RTH (j-c) + RTH (c-a)]
P:
expressed in W
ΔT:
RTH
difference between maximum working temperature and room temperature
:
:
(j-c): thermal resistance value measured between resistive layer and outer side of the resistor. It is the thermal
resistance of the component: (Special Features Table)
RTH
(c-a): thermal resistance value measured between outer side of the resistor and room temperature. It is the thermal
resistance of the heatsink itself (type, shape) and the quality of the fastening device.
Example:
TH: (c-a) for RTO 20 power rating 10 W at ambient temperature + 25 °C
R
Thermal resistance RTH (j-c): 6.5 °C/W
Considering equation (1) we have:
ΔT = 155 °C - 25 °C = 130 °C
ΔT
P
130
---------
= 13 °C/W
-------
RTH (j-c) + RTH (c-a) =
=
10
RTH (c-a) = 13 °C/W - 6.5 °C/W = 6.5 °C/W

OVERLOADS
In any case the applied voltage must be lower than the maximum overload voltage of 375 V.
The values indicated on the graph below are applicable to resistors in air or mounted onto a heatsink.

POWER RATING CHART
The temperature of the heatsink should be maintained within the limits specified.
To improve the thermal conductivity, surfaces in contact should be coated with a silicone grease and the torque applied on the
screw for tightening should be around 1 Nm. Spring clip can also be used to mount the component on an heatsink (ex: Kunze,
clip KU4-498).
