Both the thermal curves provided and the example given above are based upon measurements made in TDK Innoveta’s
experimental test setup that is described in the Thermal Management section. Due to the large number of variables in
system design, TDK Innoveta recommends that the user verify the module’s thermal performance in the end application.
The critical component should be thermo coupled and monitored, and should not exceed the temperature limit specified in
the derating curve above. It is critical that the thermocouple be mounted in a manner that gives direct thermal contact or
significant measurement errors may result. TDK Innoveta can provide modules with a thermocouple pre-mounted to the
critical component for system verification tests.
