This is off a DC 200 volt drive on a Lagun Mill it runs the table movement one of the legs broke off and in an attempt to solder a new one on it burned
I went off of the number 22 I assumed micro farad and the 250 as volts. I ordered one to that spec and it is 10 times larger I did order 250 AC
I am enclosing the board, upon removal it was marked C5
What am I missing?

 

0.22 µF (220 nF) 250 VDC stacked metalized polyester film, possibly made by Siemens; 10 mm/0.4" lead spacing

 

Thanks a million I have a replacement on order. Since you were kind enough to answer my question do you have any tips for soldering? I do have a temp controlled soldering station, what is prompting me to ask is where I work we make our own controllers and I had a friend who does service work look at the board, after seeing the cap had it's leg tore off we tried to re solder it back on. it instantly all balled up and would not stick (the solder) upon heating the other end while UN soldering from the board the solder that was there balled up like the surface tension forced it too.
I ordered a few as replacement in case I mess up installing it

 

Generally there isn't a big issue with soldering - just work reasonably quickly. I doubt if you'll have any problems.

The film is metalized with aluminum and, as I understand it, the end metalization is applied with a sputtering or spray process and it is something of a minor miracle that it holds together. There is little hope of trying to rework it.

 

thanks again, I hope I can get the drive to work again, I am a engineer but not elec. all of this is to get an old mill to wok again this is the slow feed when milling the motor is dc 200 volt this of course is the driver made in the 70's. I can't help but to be curious why a film capacitor?
what properties does it have over all the other styles ? I wish I had a schematic of the drive there are still 2 wires that ran to a contractor and I think the were connected together to make it run, I understand all of the others, again thanks for the help.
if I post what I have for information will you look it over?

Not possibly they are Siemens, the old style without any encapsulation, over time they can absorb moisture, oils, grease, dust

Similar kinds are often sold as CBB capacitor

One thing about these capacitors is you should never work them close to or at the rated voltage, and DC rating is not AC rating.

Most will survive much higher voltage at first, like 3x or 4x as much, but statistically after some while, some will fail even at only rated voltage.

Theres some with self healing properties (the discharge will leave a puncture) and some without (failure, sparks, fire at worst).
