CAP Thermal is a simulation tool that helps engineers calculate the thermal performance and lifetime of TDK’s power capacitors under real operating conditions.

CAP Thermal allows you to model the thermal behavior of our power capacitor families based on your specific application parameters, including RMS current spectrum, ambient temperature, and cooling conditions.
