Hello,

I am looking for the Junction-to-Case Thermal Resistance of the VQFN-68 LM98640 ?

  • Nicolas,

    I will submit a thermal modeling request for this device. It may take 2-3 weeks to be processed.

    Other devices with a similar package have a Rjc of 2.7 C/W. That may give you an educated guess for what to expect.

    Nicholas,

    I received the response from our modeling team earlier than expected!

    Rjc(top) is 7 C/W
    Rjc(bottom) is 0.5 C/W
