MAX3243CPWR Junction to case thermal resistance

GaryC

May I know what is the Junction to case thermal resistance of MAX3243CPWR? Since I don’t see this in the datasheet. Thanks.

Gary,

I did not find this model. I will request a new model. This normally take 2 to 3 days.
Tjc value isn't especially useful unless you plan to attach a heat sink to the top of the device.
Psi-JT value can be used to estimate junction temperature based on a measurement of to of case temperature.
Both values will be provided after model completion.

Gary,

Theta-JC = 20.2 C/W
Psi JT = 0.9 C/W
