Hi all, can you guess help me identify a couple components? I know they are capacitors, just not sure the values.

I'm trying to find replacements from Digikey.

Help is appreciated

 

22J would be 22pF.
221 would be 220pF.

 

MrChips thank you.

Would this be 1KV or 2KV?

This is for an LCD TV power supply

 

I am not convinced that they are capacitors. They could be polyfuses.
What is the make and model number of the TV?
Can you post more photos of the entire power supply from different angles so that perhaps we can reverse engineer the module and see the role that those components play?

 

I'll have to take some more in addition to these

Yes, they are caps. These caps are safety rated and are the only parts allowed to make direct connections from the "hot" side of a SMPS to the "cold" side.

Why do you suspect that these caps need to be replaced?

It's not my thread, but I agree that these parts are fairly bulletproof (but I have seen them bad before). I don't know what the OP is trying to do.

 

Sorry, this should be directed to the TS.

CP813 the back blew out so I'm going to order that, I also know one mosfet is blown.

I figured with shipping why not order one each of the caps just in case.

Replacing components in that manner is simply shooting in the dark.

 

I’m replacing capacitor cp813 I knew that one blew out the bad physically. One mosfet I desoldered was bad the other I removed tested good. I was getting funny readings on the rectifier when ohming our dc & ac terminals but when I removed it, it tested good and the fuse blew so I need to change that. Guess go from there I’m limited to equipment I have to test. Basically just a fluke voltage meter but it does have diode and limited capacitor test capability.

I saw on another forum you could put a 60 watt bulb in where the fuse was and see if there were more shorts but could find that much info on it

If they are caps, they are rated for 500V-750V, but I can't make out the text next to each of those specs. Everything you need to know is right on the component, including part#

 

Also the mosfets do you all suggest the paste or the silicon rubber pads? Below is what I found I just have 2 mosfets to install.

any suggestions on the mosfet paste or silicon pads? Also would paste have to be non-conductive?
