CDCLVP111-SP: How do you calculate theta-jb in the datasheet?

tom Caltabellotta

Part Number: CDCLVP111-SP

What thermal paths are assumed in the datasheet value of 98.9°C/W? Under what ambient conditions?

Also, what material are the leads made from? I've been assuming kovar leads attached to a ceramic substrate.

Thank-you very much!

Hello Tom,

In the datasheet is a link to this app note on thermal metrics. Note that the numbers in the datasheet are modeled and not measured for each product:

Package construction can be found on the product page in the ordering table on the link in the right most column. The leads are NiAu plated Kovar.

Let me know if you have any more questions.
