can you identify this capacitor?

[kropka235]

hi,
i dont even know if that is a capacitor?,...its looks like a Russian bypass cap placed over big electrolytic capacitors in my amplifier,...could you tell me what that little grey thing can be?
thanks

Yes, looks like a capacitor - possibly some sort of plastic film type? I'm sure others will help you decipher the Russian markings. With long legs like that it won't be doing much as a bypass.

 

[kropka235]

...thanx for reply,
i still would like to know more about it.

 

[Refugee1]

It looks like it could be part of a capacitor-resistor-capacitor filter.
This would make the 0,5 0.5 ohms.
Is it connected between the positive terminals of the large capacitors?

 

[kropka235]

...yes it is connected between the positive terminals of a large cap andi think you are right Refugee1 ,...and ive already found out that itsn't a capacitor ...its a Russian carbon resistor
thanx for your help.

 

[Refugee1]

It looks to me more like a Russian copy of the square white ones we see on British gear. They are wire wound and the resistor is cemented into a ceramic body to make it more durable.

It look like resistor. Google "С2-13" - in cyrillic

Ìóçåé ýëåêòðîííûõ ðàðèòåòîâ - Ïàññèâ - Ñ2-13

Taking advantage of the open thread, can someone identify the "date" of manufaturing of this cap? All that can be seen is this 02D05L 05 sign...

Thanks.

Google is your friend. Turned up this

So yours are apparently made in 2000 on the 4th of Feb.

Thank you!

Actually mine are SMH series and are coded 0NM05L 14 → 2010, November 13th - Line 05 Lansing ??

Hello, can anyone help me find out what kind this capacitor is?

Thanks

 

[Capt Grogg]

looks like Siemens stacked mylar

 

[rodrigosalvati]

Thanks. Would you think its a good idea to swap them out for polipro film? They are in the signal path of the eq of my mixer channels.

 

[Refugee1]

I have used those Siemens ones in the past.
The only problem was if on a double sided PCB there was a track running underneath and high voltage involved they could arc from the edge of the stack to the track.
Apart from that and the ends not being insulated they are fine and have low inductance.
I don't see a problem with the board they are shown in there.

 

[rodrigosalvati]

Thanks for the advice.

In this picture are the blue ones tantalum, and the small red ceramic?

If so, is it recomended to replace with another type?

 

[AndrewT]

the thin 22nF are almost certainly hiK ceramic.

 

[EssB]

the thin 22nF are almost certainly hiK ceramic.

.. and somewhat microphonic.

I still have a few of them in my stock, from 35 years ago. They were cheap junkbox parts even then.

 

[rodrigosalvati]

Thank you. What would be the best replacement?

 

[AndrewT]

depends on what each is expected to do.
The duty they perform determines the selection of a suitable type and a suitable size and a suitable value.
Note: size is the physical volume and pin pitch.

 

[rodrigosalvati]

I am analazing the channel circuit on my mixer. There is one of these 22pF capacitors on the first 741 op amp, but I dont know what it does. I am also looking to swap out the 741 for tlo71 as I have read its a safe transition, so I would like to know if it is needed with the new op amps, or if it is worth exchanging.


Thanks
