What component type / value is this?
Just been doing some fault finding and this Tesla brown item looks cracked so will be replacing it hopefully. Its marked:
TC 181 MP M33 160V = JY Does any of that make sense? I was thinking it was a capacitor but don't see a value. Thanks for any help. |

Safe bet to me.

Re: What component type / value is this?
Thank you both kindly. I would never have worked that one out! The other one was a 50uF axial - a rare value for sure.

Re: What component type / value is this?
47uf can be used to replace 50uf without any problems, btw.

Re: What component type / value is this?
They're only rare over here. They're off-the-shelf in the USA http://uk.farnell.com/vishay/tva1512...tor/dp/1199627. In fact RS list them at lower voltages but if you need >150V they don't seem to have those in the catalogue.
Cheers, GJ

Re: What component type / value is this?
For the 50uF I have either 47 (measures 45) or 56 (measures 53.5). I suppose either would do and the original was only 12 Volt rated so not a high stress application.
I have found that even the 10nF ones have dried out so its a blanket replacement job. Good job that there is only 8. Got all the others on order now so hopefully an easy fix. |

Re: What component type / value is this?
That Tesla cap is very reminiscent of crumbly brown 'orrible Hunts that abound in '50s/early '60s kit. I expect that every nation has its own particular MCC (Most Cursed Capacitor).

Re: What component type / value is this?
Out of curiosity. does that cap have Chinese symbols? Or is it my eyes

No, it says "TESLA"

Re: What component type / value is this?
What's the equipment it's fitted in?

Re: What component type / value is this?
Yes, remember that by virtue of the way they work, electrolytics always have a wide tolerance [something like +/- 20% being typical] so you don't need to fret about getting an exact replacement - anything between 40 and 70 uF will do provided it's got an adequate voltage-rating.

Re: What component type / value is this?
Just to wrap up I fitted all the new components and now the unit functions perfectly - thanks to all who helped me. And to disperse any doubts that it was 330nF I opened up a second faulty unit that I am fixing and in that one its clearly marked 330n.
