[TechAssist] Re: Panasonic SA-CH94M

I cant answer that question with absolute authority but I would guess that
the letters at the end have to do with gain, package, and lead
configuration. The resistors are integrated into the die so the tolerance is
probably very high, maybe plus or minus 30 percent.

> I agree with you they are digital transistor but what about the last 3
letter TSTand EST do you know what those meant. I ask you becouse if you
found a transistor with the same number like DTC143 TST and found another
with the same number but the last 3 letter are diferent and you measure both
you will find out the resistence are not the same.
