APPLICATION NOTES
Proper heat sinking techniques are essential to performance of a
TAP1000 resistor. Pleased follow these guidelines when designing
TAP1000 system:
• Heat sink compound must always be used. Phase change material is
preferred over silicon pastes.
• Heats sink plate (base plate of the resistor) temperature must be
monitored to establish proper de-rating. Best technique 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.
• Due to very high power density, only liquid cooled heat sinks are rec-
ommended for applications when >300W power rating is desired.
• Properly designed heat sink should have more than 2 cooling pipes
under the surface of the TAP1000 resistor. Hydroblok-1000, a 4 pass
aluminum heat sink (http://www.d6industries.com/HeatSinks.htm) is an
example of properly designed heat sink.
