What is the operating temperature of PCB® model 377B02?

The operating temperature for the microphone is listed at 150C. It is important to note that the microphone requires a preamplifier and the preamplifier will be the limiting factor. Standard 1/2" preamplifiers range from 60C to 80C but PCB® was the first manufacturer to introduce a high temperature preamplifier that when mated with  377B02 can be used to 125C.
