h PARAMETERS
VCE = 10 Vdc, f = 1.0 kHZ, TA = 25oC
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.
