Electronic Part Identification Help

Dec 20, 2023 Last reply: 2 years ago 11 Replies

Hello all,



I know this will be a bit of a PITA for some, but................



Recently I had a electronic board that was hit by a Lightning Strike or voltage surge and things got a bit messy.



Looking at the board where 120vac is connected just past the input terminals and before the step-down transformer there are two(2) small components that smoked. I can't see any ID on the device because of the strike. But, they are about 1/4" to 3/8" diameter with a small open slot at the top end. The slot might be .030" wide. Two terminals are soldered to the board. Oh and the color of the component is black, which I think it was before the strike.



The open "slot" on the component should trigger a easy suggestion for those that want to assist!!



What would be helpful for this 'old man' would be a name that would fit this kind of component. Maybe a MOV?? But, I don't think that is what it really is.



That is where I need a little assist. It will help me do some searching to find a replacement component and see if just swapping out will do the fix.



And no, I don't have any schematics at this time.



Again, just looking for a part name to begin my searching.



This is just a hobby adventure for fun!!



Thanks,



Les


Manufacture and model number would help. In other words more information.

Any photos to share?

Sorry the picture I have at this time is very dark. So the black component is just a glob of black. Thanks for the "jlaforums" link. Didn't know that existed or that this newsgroup was transferred over.

As for the other question of manufacture or model number. I would not think it would be necessary for the the question and I would prefer not to divulge that info to the group. Won't help.

Thanks for the questions, sorry I can't provide more input.

It's not transferred, just copied for lurking, it's still in /sci/ electronics/repair

Okay, you think, you don't want help!

:(

so against my rules, some advice:

It seems these some kinda capacititors with an overvoltage protection. verify, that they are between Phase and Neutral. If so, I'm right.

Then desolder them and check if your device is running or has more damage.

Obey the rules for working on hot lines or you will be killed!

You have a very small chance, that only the protection is killed.

Report your results

You "would not think it's necessary" & clearly you don't know s*it, so how would you know whether it's necessary?

The 'slot' is a crude spark gap, which may be discrete or introduced to a ceramic capacitor's structure.

To allow downstream faultfinding, the unit will normally run without them in place, while you search for a replacement part, .

Thanks RL!! That is the 'tiny bit' of info I needed.

I need to define more but that is the start point that I couldn't place!

As for all the other comments............ As I said at the top: I know this will be a bit of a PITA for some. Sorry to you all.

Thanks again RL!!

Have a good holiday season or what ever kind you desire!!

If you had posted that information, we could have answered the question easily - but no, you had to be a PITA. Fortunately, the part was found. It is critical to the operation of the machine from which it comes - the Retro model of the Rockwell Turbo Encabulator. The part in question is the dingle arm. Good luck in finding one! Merry Christmas. Ed

Hello again,

During these times of massive amounts of junk on the Newsgroups with excessive un-readable crap like this:

LEGHISTA ARRESTATO LUCA SOSTEGNI SCAPPAVA A PORTO SEGURO

I would think that those that frequent this newsgroup would somewhat enjoy the PITA posting for some electronic help. Obviously I was only a little wrong. It was nice to receive the small tidbit of needed information to assist me in my endeavor!!

Thanks very much, I will now continue my search for the Anatomic Nuclear Capacitor w/ .030" Butt Crack :-)

Have a good Holiday Season!!

Don't let the door hit you on the way out. You're welcome to have a spam filter if you want one.
