Proper heat sinking techniques are essential to performance of
a TAP resistor. Pleased follow these guidelines when designing
TAP system:

• Heats sink plate (base plate of the resistor) temperature
must be monitored to establish proper de-rating. Best tech-
nique is to attach a thermocouple to the side of the base
plate of the resistor. Temperature of plastic housing or heat
sink cannot be used to establish rating of the resistor. Usage
of laser thermometers should be avoided.

• To obtain a power rating of 1000W or 2000W, the bottom
case temp must not exceed 85°C. This can only be achieved
if the thermal conduction to the heatsink Rth-cs<0.025°K/W.
This value can be reached by using thermal transfer com-
pound with a heat conductivity of 1W/mK. The flatness of
the cooling plate must be better than 0.05mm overall. The
roughness of the surface should not exceed 6.4µm.
• Due to very high power density, only liquid cooled heat sinks
are recommended for applications when >300W power rating
is desired.

• Properly designed heat sink should have more than 2 cooling
pipes under the surface of the TAP resistor. The Ohmite CP4
heat sink (http://www.ohmite.com/cat/sink_cp4.pdf) is an
example of properly designed heat sink.
