Re: do you know a mosfet with smaller than 0,05Ohm resistanc
there are plenty of mosfets with smaller chanel resistance so look foor N channel mosfets those are the one with smaller resistances .the smaller the resistance the pricier those devices get .
Just going trougn my digikey CATALOG ,, i see a lot from FAIRCHILD like
NDB7060lct-ND RDSon = 0.015( $16 by one or half by 100)
there is even a 0.008
digikey is not the best plave to buy ,,but is the one that i consult at first because they carry a lot of stuff ..once i know who makes what i need then i look for the cheaper place to buy ,... i mean if i have to buy in bulk ..
