#252 In this video I look at how the thermal behavior of a component can be modeled in the circuit simulator. I go trough multiple types of models, from the very simple thermal resistance only to the more complex, RC - transient models, and finally look at an all in one model - a component that simulates both the electrical and the thermal behavior at the same time.
Tutorials on thermal behaviour:
Basics of thermal: youtu.be/G9RU4uHwROw
LTspice Simulating NTC's: youtu.be/BAaCT0TOh2s
LTspice Effect of temperature on the circuit: youtu.be/VzxnNrOMcMo
LTspice Static and Transient models: youtu.be/BGi_n28D8ro
Datasheets and further reading:
