Default What kind of resistor do you use?

I ordered a bunch of 1/2 watt metal film vishay resistors, and assumed they would be the size of carbon. When I got them, I assumed someone filled the order wrong and gave me 1/8 watt resistors..they are soooo tiny. They are about 2.5 mm diameter, and 4 or 5 mm long. I verified that they are indeed 1/2 watt resistors. I do not want to use them.
What do you guys use for standard 1/2 watt signal resistorss?

They are Vishays. Why wouldn't you want to use them?

+1 for Mr. Pass. I have been using Vishays from Texas Components for 20 years. They are among the best in the world. Regards John Dozier

I guess I will use them..I already have them. It is just that they are so tiny. I guess I am old school..used to seeing a 1/2 watt resistor being about 1/8 inch in diameter and about a 1/2 inch long. These things are seriously about the size of a grain of rice. The short grain variety

Hey, Mark--I can understand you not wanting to use those little, tiny resistors. In fact, if you just want to mail them to me, I'll dispose of them for you!

Industry! Science and Technology! Men putting screwdrivers into things. Turning them, and ad-justing them!
(Semi-Obscure movie reference)

Seriously though, the technology has just improved and miniaturized.

isn't cooling in resistors a function of size ? Unless these Vishays are made of some exotic material with extremely high thermal emissivity, it seems reasonable to assume that they will run at a much higher temperature than a conventionally sized 1/2W resistor ?

(and that is a bad thing. right ?)
