This group of graphs illustrates the relationship between

h

fe

and other “h” parameters for this series of transistors. To

obtain these curves, a high−gain and a low−gain unit were

selected from the 2N4403 lines, and the same units were

used to develop the correspondingly−numbered curves on

each graph.
