Can thin sections of copper traces be used as fuses ?

Postby maryzhu » Thu Jun 01, 2017 7:00 am

Hello all. Thanks for taking up your time to read my post.

Is it safe to use thin sections of copper traces as one-shot fuses when cost is important, but when it is also vital to protect the rest of the circuitry? Should the solder mask be removed at that location? What about using 0R resistances in small packages as resettable fuses?

That's for applications for JTN60030 as the datasheet of when time to fuse is not critical compared to the location of the failure. For more demanding applications, are there I-t graphs of tracks of various widths available? I have not found any.

Can anyone help me ? I am very puzzled about this question. I do need your help.

thanks in advance
