CHOICE OF THE HEATSINK

The user must choose the board 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

T

P = -------------------------------------------------------------------------------------------

+ R

TH (j - c)

TH (c - h) TH (h - a)

Expressed in W

T:

Difference between maximum working temperature and room temperature

R_{TH (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.

_{TH (c - h)}: Thermal resistance value measured between outer side of the resistor and upper side of the heatsink. This is the

thermal resistance of the interface (grease, thermal pad), and the quality of the fastening device.

R_{th (h - a)}

: Thermal resistance of the heatsink.

Examꢁle:

_{TH (c - a)}for RTO 20 power rating 10 W at ambient temperature +25 °C

Thermal resistance R_{TH (j - c)}: 6.5 °C/W 

Considering equation ⁽¹⁾we have:

T = 155 °C - 25 °C = 130 °C 

T

130

R_{TH (j - c)}+ R_{TH (c - h)}+ R_{TH (h - a)}= ------ = -------- = 13 °C/W

R_{TH (c - h)}+ R_{TH (h - a)}= 13 °C/W - 6.5 °C/W = 6.5 °C/W

OVERLOADS

POWER RATING

In any case the applied voltage must be lower than the

maximum overload voltage of 750 V.

The temperature of the heatsink should be maintained within

the limits specified.

The values indicated on the graph below are applicable to

resistors in air or mounted onto a heatsink.

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).
