BFQ42
V.H.F. POWER TRANSISTOR
N-P-N silicon planar epitaxial transistor intended for use in class-A, 8 or C operated mobile
transmitters with a nominal supply voltage of 13,5 V. The transistor is resistance stabilized and is
guaranteed to withstand severe load mismatch conditions with a supply over-voltage to 16,5 V. The
BFQ42 is especially suited asa driver transistor for the BLW29 in a two-stage wideband or semi-wide-
band v.h.f. amplifier delivering 15 W output power.
It has a TO-39 metal envelope with the collector connected to the case.
