Thermal Resistance Values for M24128-DRMF3TG/K

Hi,

Could you please provide:

  • T_Jmax (maximum Junction Temperature)
  • R_JA(Junction to Ambient Thermal Resistance)
  • R_JC (Junction to Case)
  • R_JB (Junction to Board)

for the M24128-DRMF3TG/K.

there are no direct thermal information dedicated about this part number. Do you think different part number with same package type be helpful?

Since this is not a high power device, exact thermal resistance values are less critical. If available, thermal resistance values from other part numbers with the same package type, preferably representing the higher end of the range, wouild be helpful, thx!

Did you see the links I posted?

There’s a worked example there ...

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

The Ambient Operating temperature is in the datasheet:

 

I guess it’s not considered a high-power device, so there’s no need to worry about those other measurements?

 

PS:

 

Basically the same question & answer here:
