Identify resistance

[altec9440]

Helllo,

I was given NOS resistances. I browsed the web in order to identify manufacturer and series without success.

May wise initiates of this forum could bring me the light !

thanks

11,4Kohm, 0,5%
Can´t find info on brand though

 

[turk 182]

is it in fact a resistor?

 

[AllenB]

It doesn't look like a resistor. Have seen inductors packaged in this shape.

 

[amplidude]

Try measuring it, maybe with LCR meter as turk said could also be something else, inductor.current sensor..?

 

[altec9440]

thanks for trying to help me.

I have several values and each correspond to marking. (11K4 for one on the picture).
HP or Metrix confirm tolerance.

There is spiral line around colours values that I did not saw before on usuals manufacturers.

have a nice day

It looks very much like a Sfernice precision type made in the 70's and 80's.
No idea about the type N°, but if you can find databooks of that era, you will probably find it

Vishay still produce similar resistor. But the NOS are non magnetic and better sounding.

thanks for answers. ,

I will explore sfernice idea but it's difficult as documents from this time was printed.

Thanks johnego, for this fact that I did not know.

To be more accurate, they must be from SOVCOR (which was acquired by Sfernice)

hello friends,

French sovcor office, did not recognize resistance, perhaps because young workers do not know vintage products 😉

I was directed to TR5 corning electrosil glass tin oxide but I can't find any datasheet to confirm. Do someone of this august assembly have litterature ?

thanks

There are several similar resistors, differs in the end cap etc...
