Default Asking help for resistor

I have a sample of a resistor that measures 9mmD x 19mmL (2nd one from the top with 180R mark on it). Does anybody have any idea about the manufacturer?

I have also seen one with a 'ohm' mark and a triangle around the mark on it which size looks very like the one I had. I did check ohmite but doesn't seem to able to find anything about it.

Can somebody provide information about them? Tks a lot for the help.

well, Ohmite was my first guess too, without even completely reading your post! the Ohm sign inthe triangle made me think that. What did it come out of? I have some resistors here that seem to be of Russian origin, making it very difficult to find again.
Why do you want the exact same manufacturer? It just looks like a simple wirewound 5 watt resistor.
Alot of other companies make them with the same look. Try Vishay.

hello.
the little grey one in front seems to be a 2watt wirewound res.
the green in the mid a 2watt metal oxide res (b&i,bi technologies?).
in the back a 5watt wirewound res.
the problem is : these are new old stock, hard to get because they are not "rohs conform",not sold further on.
greetings..............

Tks for your response.

I am not exactly looking for the manufacturer but if you don't know anything about them, you could not find any reference point to start with. What I am after is the size 9mmD x 20mmL that is most important. I did try vishay but their AC05 is smaller :
7mm x 17mm which is not exactly what I had in mind (2nd choice if the 9x19 is not available). The aspect ratio of it makes it look more elegant. Actually, the smallest green one in the front is a special ordered one : 5w wound on a 3w rig. It works OK but sure it doesn't look OK.

The 'Ohmite' in the second photo is just what I saw someone selling, I don't have it. The light green one in the 1st photo is what I had in hand now. In fact, the 'Ohmite' should be good enough, if I can ever find them. I had check ohmite's product catalogue but haven't yet find it.

I am not too sure which green one you are referring to. The deep green or the lighter green? I hope you are not referring to the light green one. I expect that it should be a 5W with that kind of size.

Default potentiometer question

I have a circuit diagram that calls for a 5K Key=A potentiometer. Can anyone tell me what Key=A means.

Tks mjf, but I am looking for the ones with the resistance printed and not the color code.
