What is this part?

I had an accident with an RCA TV...video card on side has 2 cap like components...glued on...yes glued to the soldering connections..They have a small black plate that was glued to the board to make the connections...looks like a small electrolytic..Numbers on can are 220 10V PZ...does anyone know what these are? I am thinking diodes...I searched the internet and can't find anything using these codes...I need to replace them..TV is nearly new..but I can't get new leads to solder on them and then to the board...any ideas, any suggestions...throw it away? Thanks again...

Mme Cindy. . . . .
oh Cindy
. .

What you do ? . . . .try to unplug it ?

Me thinks that you have found yourself a surface mount electrolytic for flow soldering installation.

Its- a- look- a- like- a . . . . . this . . . . top side . . .

And you can see the two foil terminls underneath it . . . on the top left corners photo. (Unfortunately . . . . iris opening was excessive and quite a bright photo.

The black referencing is the neg lead and your unit is a 220 ufd @ 10 VDC rating the other micro info tidbit is a manufacturer coding.

My procedure is to never use those types of units for replacement . . . too failure prone.

If of a 35VDC or lower rating, I will use a dry tantaluman "bead" capacitor and have the leads shortened to about 1-16 thru 1/8 in height, with the two leads ends folded out 90 degrees for about 1/16 inch.

Then tin the units leads along with the PCB foil mounting lands and then use a fine tip to reflow solder on, one lead at a time and then reposition it to the vertical position, in case you had to initially slant it . . . to get working room.

They sound like thermal fuses.

These are small, black , round devices with leads that vary their resistance in response to current.
Too much current - high resistance - it protects the circuit.

Anyone agree??

Thanks

Amen to the pic statement. Edd was right on the money...I managed to get the old ones back in with some longer legs now...Aluminum legs.....that little black plate was glued to the board...seriously..why you ask...so they will fall off and we would have to buy new TV...and they wonder why the landfills are full of toxic waste...go figure.
That is one reason we should keep repairing those old fixable ones...they are worth restoring..worth the work, and valuable to the future...for posterity and clean landfills.
Thanks for the great info...I couldn't make it without you guys...Like entire encyclopedia volumes, everything you need to know...Thanks especially to Edd...

Surface mount components are the norm for modern circuit board manufacturing. Things will just keep getting smaller and less serviceable.
Multiple layers within the board substrate carry traces, vias and passive components. If any of these fail, they can't be serviced and the board is replaced.
Many circuit boards are becoming a 'macro' chip and everything is going digital. That's why I still appreciate the old electronics.
