2N4403
h PARAMETERS
V_CE = −10 Vdc, f = 1.0 kHz, T_A = 25°C
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.
