Thermal measurement location – top view
The thermal curves provided 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 otherwise significant
measurement errors may result.
