Hey,
I was in the market for some decent quality resistors when I found the Vishay Dale CMF series. They seem to be highly regarded and look quite funky.
Since I am very new to the whole electronics design aspect of things, I have some questions regarding the differences between the regular CMF Industrial and the mil-spec RN version.
What I'm looking for are the 6.1x2.29mm sized ones so either CMF55 or RN55. What threw me off were the wattage ratings and prices.
I see them rated as 0.5W@70°C and 0.25W@125°C and in other datasheets as 0.125W@70°C and 0.10W@125°C.
Mouser has the CMF55 rated as 0.5W and the RN55 as 0.1W or 0.125W.
So my question is, are they the same thing? To me it looks like the only difference are the larger wattage and voltage margins to meet the mil spec of the RN, RN has no RoHS and maybe tighter QC?
So if I want 1/4W resistors could I just go for the RN, since in some cases they are quite a bit cheaper on Mouser?
