The maximum internal resistor temperature is 130C. To specify an appropriate heatsink use the following formula : R = T - ( P x R ) - T qH MAX qR A P Where: R = Thermal Resistance of Heatsink ( K/W ) qH R = Thermal Resistance of Resistor ( K/W ) qR T = Maximum Temperature of Resistor MAX T = Ambient Temperature of Heatsink ( C ) A P = Power Through Resistor ( W ) www.powertron.de For technical questions, Document No.: 64238 2 contact powertron vishaypg.com Revision: 25-04-2013 R/R (ppm) Power ( % from nominal power)
