https://www.allaboutcircuits.com/news/toshiba-debuts-thermoflagger-as-temperature-sensor-ic-alternative/ This seems awfully silly to me. At least it's cheap, about 13 cents. Maybe it's useful for something else.

We use NTC thermisters. What I would really like is to be able to point some kind of (cheap) IR sensor at a general area of power components and get a rough estimate. Instead of tacking thermisters to transformers and FETs which is kind of a pain. I looked into those IR sensors used in cheap $20 temperature guns but the lens assembly, I think, makes that not too easy or cheap to implement. boB

But they cost too much for this conumer grade inverter/charger application Thank you for those ideas ! boB

That is the MLX90614, a single pixel temperature sensor, not the MLX90640 which is a 32x32 'camera'. Arie.
