I always used to think of RS as expensive (but convenient). Kinds of like a 7-11 store for electronics. But that price is really good - 5 packs of 10 for 3.50UKP.

Thanks, Nige
Either I'm losing it or their search engine is as bad as this forum's search engine?
Ah, you probably use google search & not Radionic's search right?

Yea, some of their stuff can be cheaper than elsewhere but I reckon it's just an oversight on their part :)

RS have delivery charges in ireland often makes stuff not competitive, delivery seemed to be slow like 7 days for me
sometimes pricing can be a pleasant surprise
the vast majority of stuff i get is through farnell order before 6pm delivered next day with free delivery no minimum order value
mouser is fine for larger orders, digikey stuff comes with customs/vat bill :(

all search engines in online stores still need a lot of work,
i can search for a part no in the store and not find it then see it stocked there through a google search

Dual channel 35FS in Radionics for same price as 3K35FS
SSM6N35FU
Don't know if dual channel is advantage - matched mosfets but even if not getting two for price of one & easier to handle?

From the DS, can't see anything that indicates they're matched. Two for the price of one has to be good but they may not be easier to solder - pin spacing is 0.65mm. Which might be manageable when there are just two pins, means you have space either side. Getting to that middle pin could be a pain.

what effect does the input capacitance have?
