LM334: Thermal Resistance Junction to Board

Leo Coic

Part Number: LM334

Hi,

I cannot seem to find the Thermal resistance between Junction and Board (either Theta JB or Psi JB) in the datasheet. Has this measurement been done already and is this information available somewhere?

Thanks in advance,

Hi Leo,

Some of these older devices are missing information.

What is the exact OPN you need the data for and I can request it.

Hi Marcoo,

Thank you for taking the time to handle my issue, I don't have the exact OPN used in my design yet, I'll get back to you as soon as I do !

Does the thermal resistance change significantly with the different versions?

Thank you again, have a nice day.
Leo

Hi Leo,

The request will take 2-3 weeks. There is a huge variance between package types and this device has a variety of package options.
