NMB1002 HV Transformer

[djordje]

Hello,

I have a question about this NMB1002 High Voltage Transformer. Can i buy NMB0002? If someone is confused its just difference in first digit, in my case is 1 and the one that i can buy is 0.

Thank you!

They do not look like they have the same pinout.

I looked at the pictures from budm and it looks like NMB1002 is surface mount and NMB0002 is through hole.

Re: NMB1002 HV Transformer

Is there any substitute for NMB1002 or i need to find original?

NMB1002 is SMD and i mentioned NMB0002 whic is through hole but in fact that is not big problem in both cases

Re: NMB1002 HV Transformer

I checked that picture you gave me Budm for HV NMB0002 Transformer and i think that the pin out is same as on NMB1002. I am posting a picture of a NMB0002 from site you gave me but i marked it in 2 colors.

Red shows pins that are connected
Black shows pins that are disconnected

It doesnt mater that one transformer is smd and other isnt.

And i am also posting pictures from mine transformer from left and right side,and it can be concluded that pins are same,difference is only that pins on my transformer that are not connected(and they are in same order not connected on picture that budm posted for NMB0002) have just short pins and from top picture they look like they dont exist.

Hope that i explained this clearly and just to mention once again i compared picture of NMB0002 with mine NMB1002.

Re: NMB1002 HV Transformer

The question is how the NMB0002 and the NMB1002 winding are terminated to each pins, and the pin assignment may or may not be the same. There must be a reason why they are not using the same form factor. Beside, you need to know the impedance, the DCR, etc. You cannot really tell until you test them out or find the specification for both transformers to verify.
