Hi Massimo,

Try http://www.vtm.co.uk/.

They had a good calculation method in the printed version of their
catalog which does not seem to be available on the website ( I haven't
looked very hard for it). It worked well for sizing in-rush limiting resistors.

Regards

- Chris

Subject:        Resistors pulse loading capabilities


Does anybody out of there know what are the methods to evaluate resistors
pulse loading capabilities (maximum peak pulse voltage without failing to
open circuit)?
Is there any standard models?
This could be very useful to design the power supply circuit parts involved
in a surge immunity test.

Thanks in advance.
m.p.
