I am looking for a capacitor with the following requirements. I looked in may distributor websites but did not find it
1µF/25V 10% 402 Pkg X7R

can anyone help to find me a similar or same kind of capacitor

 

Your problem is the operating voltage (25V) vs package (0402).

You can either reduce the voltage or increase the package size (0603 for example).

 

I cannot change my operating voltage and also package size. because its already in layout state

 

Then change the temp range from X7R to X6S.

 

Hello,

X7R is not available in that size and values.
X5R and X6S are available here:

Ok thank you

 

still not satisfied as i am looking for the similar temp range from X7R.
Thanks for your inputs

 

Hello,

Why do you need a high temperature of 125 °C ?

digikey not x7r 1uf 25V 10% 0402

 

Hello,

For X7R the minimum size is 0603:

With 0402 you will not find any in X7R.

We've all done it
you need to re spin your board then,

Sorry , the rules of physics say "at the moment", an 0402 at that voltage and capacitance does not exist in X7

 

Could you please let me know which is the nearest alternative which i can use

 

just look on the sites such as digikey ,
the biggest 0402, 25V X7R I can see is 220 nf

 

Here are your constraints:

1 - value = 1μF
2 - voltage = 25V
3 - temperature range = X7R
4 - package = 0402
5 - PCB layout

Change any one of those and you have a fit.

Edit: Before someone jumps on me, I know, changing 4 and 5 are two changes.

 

just look on the sites such as digikey ,
the highest voltage for 0402, X7R , 1 μF, I can see is 6.3 V

How about 4 of them in series, a sort of supper tomb stone affare on the board.
