We need to have a load resistance to match an internal resistance for peak power.. so we've decided to use a Power MOSFET as the varying load resistance, but my question is.. when I'm looking for which power MOSFET to buy, to use, what should I be looking for in terms of properties?(adsbygoogle = window.adsbygoogle || []).push({});

This is what we need:

The Power MOSFET....

1) Has to be able to handle the ~25W of power that will be fed into it

2) The resistance has to vary between a couple ohms and 25 ohms.

Any ideas?
