THIS PRODUCT IS DESIGNED FOR
USE WITH PROPER HEATSINKING.
Maximum base plate temperature of the resistor must
be monitored and kept within specified limits to es-
tablish the power rating. Best technique is to attach a
thermocouple to the side of the base plate of the resis-
tor. Temperature of plastic housing or heat sink cannot
be used to establish rating of the resistor.
