@@gsilva220 Traditionally the thermistor is an NTC device because it is made from a non doped semiconductor and the conductivity increases as the temperature increases because more electrons are given energy and are kicked up from the valence band to the conduction band. PTC thermistors, often referred to as silistors, arise as a result of extrinsically doping a piece of semiconductor material.
The effect is not as big. In reverse bias, the current that flows is a minority saturation current, it is very low, and all the heat is doing is enabling that to increase a little. It is not a replacement for a thermistor.

So who remembers the varistor/thermistor combination that activated the degaussing coil on old timey television sets?
Could you explain how it works ?
what a cool word
Resistance of a thermistor is not proportional to temperature.
It is inversely proportional.
There are both types, PTC and NTC

Inversely proportional is a type of proportional relationship 🥂
@@heavenlymonkey They are in fact complete inverses of each other.
Now hand it over to eletrodoom guy😂😂
Lots of intresting components on this short, so much information :) Do inductors next!
Nice selection of components 👍👍 Thanks
Varicap: You may well have solved the mystery of what I found in the tuning section of an old video recorder.
quite exotic components for sure! you won't need these in most of the common circuits.
Are the suppressors also called transorbs or that's another component? Also, they seem to work like two zeners connected face-to-face.
Informative.
Insted of a thermistor, you can also use a standard diode conected in the reverversed way. The heat will change the resistance

more more more!
I knew 4 of them!
