I know that I'm just a little out of topic, but maybe some of you can help me.
I have found a xref table for US made SMD transistors where, from the number
you can read over one of it, you can know the part number and the equivalence
to a traditional transistor.
I want to know if any of you have or know where I can found the same for JAPAN
made ones.
