h PARAMETERS
VCE = 10 Vdc, f = 1.0 kHz, TA = 25°C
This group of graphs illustrates the relationship between
hfe and other âhâ parameters for this series of transistors. To
obtain these curves, a highâgain and a lowâgain unit were
selected from the 2N4401 lines, and the same units were
used to develop the correspondingly numbered curves on
each graph.
