While at MOSFETs, those little fellows here seem to be quite capable to handle LED strips (SSM3K324R) - again, PWM at 3.3V logic level. They should be able to handle up to 1A safe and sound in this setup, I guess. Why are spec sheets always guesswork. Just a real nightmare to solder these… guess I finally need to figure out where to order PCBs with parts already assembled :/

I stumbled upon this, and ordered the MOSFET and GaN FET Applications book. Looks like there's some other good stuff too, if you don't mind giving them an address you have access to:

So schaut es aus wenn ein Mosfet - welches der Temperaturüberwachung und -kontrolle dient - seinen Dienst verweigert, also ausfällt.

Ich habe selbst die X-3 Serie von Qidi hier bei mir und mich aber selbst lange nicht mehr bewusst damit auseinandergesetzt.

Allerdings sollte gerade jetzt, wo die meisten Drucker mit geschlossenen Bauraum und höheren Temperaturen und Bauraumheizung daher kommen dieses Thema ernster genommen werden !!!

Electronics idea.

There are opamps with bipolar junction transistors (BJT) in the input stage.

There are others with junction field-effect transistors (JFET) in the input stage.

There are yet others with metal-oxide semiconductor field effect transistors (MOSFET) [1] in the input stage.

Idea: find an application for the bizarre possibility of an opamp with insulated-gate bipolar transistors (IGBT) in the input stage. This is more stunt-designing than anything practical.

[1] IIUC, "CMOS" opamps are really just MOSFET-input opamps. I'm not sure why the process technology name is more commonly used rather than the device type as is universally used for BJT and JFET input opamps.
