its 630V564J i can't find this value capacitor in local market...
Instead of this which type capacitor can use alternatively.?
 

Hi,

564 --> 56 * 10^4 pF = 560nF

From the size I´m not sure. I´d expect a larger size.

Klaus
 

why they used 630v..?
Is their any reason..?
I found this capacitor in motor...

You ask us?

How can we know? We don´t see the device where you put it from. We don´t see any circuit. We don´t see the power supply voltage.

We only have that much information that you provide.

Klaus
 

The Voltage is the max Voltage the capacitor can sustain .. Absolute max ratings .. You can use this capacitor for any application with threshold levels below this ..
 

instead of this one shall i use 470J 630V.?
It used in an motor...Their is no nameplate or something else about the motor....
the motor is driven by single phase AC 230V....

Go ahead; try but 47pF is too small for a motor to start. If you multimeter can also measure capacitance, measure both and see the difference.

In post#2 I told you how to get the capacitance value from the code.

Therefore you should be able to rcognize that the one is 560nF and the other is just 47pF
--> you need about 12 thousand pieces of the 47pF to get the equal capacitance of 560nF.

I don´t think it makes sense to use it.

I can't find the value higher than 470nF in my local market...I referred with capacitor code datasheet and got this data...
So i have to go to alternative way to complete my requirement.
 

Hi,

but capacitor code "470" means 47pF and not 470nF. There is a factor of 10000.

A true 470nF capacitor is just a factor 1.2 from the original value.
There is a good chance that the 470nF capacitor will work as expected.

If you have 470nF, that is equal to 0.47 uF, that is certainly going to work in place of 0.56 uF. Make sure the voltage is correct. Most capacitors have large tolerances.

yes the voltage is correct but i can't get correct value only...

Hi,

"yes the voltage is correct but i can't get correct value only..." - What do you mean, please?

If the problem is that you can only find up to 470nF where you live, then put 220nF and 330nF (and 10nF) in parallel to get 550nF (or 560nF), or 270nF and 330nF for 600nF.

Why? What do you mean? We know how to calculate this. We don't need this table.

May I ask why you don't use the 470nF one?
