This group of graphs illustrates the relationship between

hfe and 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 MMBT4401LT1 lines, and the same units

were used to develop the correspondingly numbered curves

on each graph.
