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 2N4402 line, and the same units were used
to develop the correspondingly−numbered curves on each
graph.
