Un-Identified componet

[fasner]

I need some help Identifying and replacing this componet on this PCB. It came from a Samsung 914V LCD with some video issues. I happened to notice one of this componets was loose and now it has fallen off. How to replace and resolder. Number on top of the part is T0500 100 16J. Thank you

surface mount cap. 100 volt I think. The 16J is the microfarads or pico or nano. There are charts out the on the web for the usual markings.

Definitely not 100 volt... there's shouldn't be any voltage over 12 volts in that area - I would dare to say nothing even higher than 5v but there are exceptions.

It's probably a 100uF, 16v surface mount capacitor.

I agree with mariushm. Resoldering it is fairly easy provided the solder joint failed. If the solder tabs broke off, you'll have to get a new one. Do you have a soldering iron, solder, and a DMM or VOM? Orientation is important; if you put it in backwards bad things will happen.

Yes I have an iron and meter, I made note of the orientation. It is consistent with the other caps in that area. I am not familar with how to solder the cap and capsule below it. Do I just mount them both and get the solder hot below the plastic base?

Re: Un-Identified componet

These capacitors have the contacts on the bottom and go a bit outside the plastic square, like you see here in this picture:



You center those two metal parts over the golden rectangles on the board so that a part of those can be seen... then solder the two sides.

As for the actual soldering, it can be done either by having solder placed before on those contacts, and then melting it again when you place the capacitor over or the standard way of soldering.

See this youtube video, it shows how to solder various SMD components:

The other two parts are also very well made, I learned a lot from them.
