Reading Capacitor

Other Hardware General Electronics
1

hi,

I have a stereo I am trying to fix. I found that the problem is a broken surface mount capacitor. I am going to replace it with a larger ceramic disk capacitor.

The reading on the surface mount capacitor is 8, 2, and a strange symbol or number - a backward 5 / strange 2 / or maybe a Z. The strange one looks like a 7 seg. display displaying 2. All the other readings on the other capacitors (and the 2 after the 8 in this capacitor) have 2's that look like a normal 2 - curved likes just like this one - 2. I am wondering what the strange number is.

what the strange number looks like

Does anyone know what this reading is supposed to mean? Is It a mistype? Also, will replacing a surface mount capacitor with a normal sized ceramic disk capacitor work?

Thanks,
Thomas

Try it and see if it works.

Maybe start with .1uF

Does the cap have a band on one end?

How do you know it is a capacitor?

Also, i bet if you take a high quality picture of the radio someone can find you a compatable component.

Are you even sure that is a capacitor? I have never seen a surface mount capacitor with markings on it.

How do you know it is broken?

I second what he said

I second what he said

Surface mount Tantalum capacitors have markings on the epoxy packaging.

for example.

In post #1, I asked if there was a band on one side, but the OP is MIA.

What leads you to think its a surface mount capacitor that is 'broken' ?

SMT ceramic capacitors are not marked, so if your 'broken' component has markings, its likely not a ceramic capacitor.

He didn't say it was ceramic, nor did he say it was tantalum, but don't forget about smt electrolytics. They are marked as well

I cleaned the area around the component with alcohol. Before there was an area of black around the resistor (I just noticed something, it is labeled R117, I am guessing R stands for resistor) Still though, I don't know what the reading of R117 (the one I asked about in my first post) Means. I also think it is broken because when I test it with my multi-meter, the reading is really unstable, same with the resistor below it. Since I can't get a reading with my multi-meter, I need to know how to read the resistor. The one below it -that is also broken if i am right- reads 331. Does anyone know what the reading would be on both? Also how do you upload images? I tried to do it with the location in "my documents", but it didn't work.
Thanks

Using the utility at SMD resistor code calculator

R117 indicates 0.117 Ω
331 indicates 330 Ω

I think a clear picture would be the best course of action. The original post has nothing about R117 or 331 and was called a capacitor. I am not convinced it is either.

I just ripped out the resistors, and an other electrode capacitor and replaced them. I have it all done and it should work.
Thanks for the help.

What's an "electrode capacitor"?

Does anyone think we should call the fire brigade?

16

it should work.

Well, does it?

(I meant the emoji for my horrible typo)
It works
