Hello everyone. I have a card with an embedded capacitor that states: MKP63 300v (alternate). Y2 223K 40/110/56 / B The exact same only found in Chinese pages and it would take a lot to arrive. (I am from Spain) I would be grateful if you could tell me where I can get it to arrive before or explain to me what I have to take into account to buy another one that, although it is not exactly the same, is worth replacing me. The card is from a 40FV plasma cutter machine. My knowledge of electronics is limited and with this type of capacitor I get lost, hehe, 1 Thanks in advance and greetings.

Here is an image and other features in the title of a component That could be a valid replacement, surely among many others. I suggest that you present this data in a component sales trade electronics in your area that they will surely know offer you the right one.

It would be to order it online, because I live in a rural area and there are no electronic stores, the closest to 120km. and when I have gone they are not complicated, if they are not very common things or they do not have it or you have to tell them the substitute,
the photo that you sent me visually does not resemble the original at all, the original encapsulation is of those rectangular capacitors encapsulated in rigid plastic like those usually found in the inputs of the power supplies.

I don't know why something tells me that this capacitor is to reduce the voltage next to 4 diodes ... but that is perhaps the case for protection in the input line with shock coils.

It is grounded and comes from one of the 3 thick wires that go to the cutting gun, marked with the letter N.

if, as I assumed, that is a SPECIAL capacitor called X2 that is to say interference suppressors in the voltage input

pd = apparently here it is used for the exit .. uffff did not know this, every day one learns something new

Hi. Does the board work? If the component is, for example, in parallel with the power supply, it must only be protective. Is the link your capacitor? There you have your value. Regards https://www.ebay.com/itm/2pcs-Safety-Capacitors-0-0047-uF-M-300VAC-FARATRONIC-MKP63-/111345283207?_ul=AR

Yes, the board does work,
The "plasma cutting" machine works everything does not make any mistakes and you can change the intensity and select the type of cut, etc, but just when the arc is formed to start cutting it stays locked and the screen is off,
I don't know any error LED lights or anything,
All that remains is to turn it off and when it is turned on, it will work again until you cut again.
From what Axie told me is 0'022Uf,
The one you suggest is 0'047Uf,
Would that be worth it ??? I have them scrapped;
0'1 Uf but they are X1.
From 0.33Uf but X1
From 0.47 if. But from X1
I would use some of this

Hi Navij. This capacitor is part of a very important filter against electromagnetic disturbances (interferences) (EMI). "Yes" you need to replace it with another that supports the working voltage comfortably and double insulation (X2) to avoid problems in case of failure in components close to it.In addition, it is also very important that it is MKP (metallized film-propylene) for that function. I do not advise a replacement of another type, beyond the isolation voltage and its capacity are compatible. description that it makes regarding its availability to save the moment and the machine can continue to operate until the correct replacement is achieved and the repair is completed correctly. It is perfectly understood.Depending on this, momentarily, you can connect 2 capacitors of those MKP X2 of 0.047uf (thus marked either 473, or 22nF) in series would be about 23.5nF (0.0235 uf) in total resulting. And the connections between them and the circuit as narrow as possible (very important). It is not worth wiring the capacitors with pieces of cable and placing them in another sector. Finally, the issue of isolation (not mentioned) of the replacements. These (both of .047uf) should NOT be less than 150VAC each, if it is more, better in this case. I advise you to request the spare parts of the design, remember that it is a momentary solution. Greetings and luck.

Let's see if I found out, hehe
The original is from:
MKP63 300v (alternate). Y2
223K 40/110/56 / B
The ones I have are X2 and they are not MKP so they are not worth me,
I see no other solution than to ask for the original
Why is it MKP and Y2 I can't find anything online that doesn't come from China and takes 20 days.
Thank you all for your time and interest.
