#124171 - what is AF? |
I had a look into a datasheet of such a trivial part as a general-purpose PNP transistor is...
I frankly admit that I am stupid: would please anybody explain me, what is AF (as in "PNP silicon AF transistor" and "For general AF applications")? Also, why is frequency specified (f=100MHz) as a condition for determining the transition frequency (which is typ. fT=200MHz)? Interestingly enough, the subsequent fT versus IC diagram, the following conditions are stated: "VCE = parameter in V" (while the diagram contains a single curve); and "f=2GHz"... I believe this has to do with the methodology how fT is determined, but I find it very confusing... Jan Waclawek |

| More than AF is needed to specify the BC807 | 01/01/70 00:00 | |

| Right! | 01/01/70 00:00 | |
