The 11th AddOhms Video is live and the subject is What is a MOSFET, and how to use them. This turned out to be the longest video I’ve made so far. In fact, I probably should have broken off the power dissipation part, but felt it needed to be addressed. I think many non-engineers look at a MOSFET (or regulator) datasheet and see a huge power value or current rating, but not realize you need a heatsink to achieve them.

For the behind the scenes look this time, I grabbed my GoPro Hero 3+ and recorded myself doing the Voice Over track. You can watch a few minutes of it, though honestly, not sure why you would!, here.

Something new is a format change.  I decided to start moving towards showing a little bit more of me.  So I’m testing the waters with an introduction and exit.  Any comments on how this works?

  1. Hi James,

    I really like your content and I can see you put a lot of production work into it. Very well thought out and useful information!

    I do have a suggestion for your MOSFET .pdf however: Add a prominent line/field for the part number of what is represented. There is plenty of white space to write something in, but I think the part number is critical information if you want to refer back to your notes at a later date, and if you forget to include it, the exercise is a complete do-over! Thanks for your great work!

    Best Regards, Dave
