This group of graphs illustrates the relationship between selected from the 2N4403 lines, and the same units were
hfe and other “h” parameters for this series of transistors. To
obtain these curves, a high–gain and a low–gain unit were
used to develop the correspondingly–numbered curves on
each graph.
