Is the temperature of the NTC thermistor in an IGBT module the same as the junction temperature Tvj?

The temperature of the NTC thermistor and the junction temperature Tvj are different. The junction temperature Tvj becomes higher than the temperature of the NTC thermistor. The thermistor is mounted on the same insulating substrate as the IGBT chip but is away from the IGBT chip. It follows the junction temperature Tvj with an offset in time.
