QuoteThey are not. The resistor is the industry standard term for a device that is designed to create the effect of resistance in a well defined manner. While electrical resistance is a physics phenomenon where something opposes the flow of current in a electrical circuit.
What is the point you are trying to make with this thread? That a diode has electrical resistance? Or that everything that exhibits electrical resistance should be called a resistor?
I am trying to uncover the roots of this cognitive dissonance. First you say that varistors are resistors that... And then you say no, they are not resistors, because resistors are only linear.
Go on that Vishay page that shows how to simulate nonlinear resistors (a term that up to a few messages ago you people thought I had invented, LOL) and simulated your resistor with an exponential characteristic. There you have your diode. It is a nonlinear resistor.
The bq27220 fuel gauge will consume a considerable amount of the CR2032s capacity.
Without monitoring, the battery lasts about a year, with monitoring you need to replace it after nine months ;-)

900V, 500A.
If you put big holes in your PCB, you can screw the studs right through the board, so I guess that's "PCB Mount".
The fun part about test equipment is, it's a one-off, we've collectively spent orders of magnitude more labor / project timeline discussing candidates, when a worst-case option is readily available for hardly an hour of shop time.
