N-channel silicon field-effect transistors BF410A to D
DESCRIPTION
Asymmetrical N-channel planar
epitaxial junction field-effect
transistors in a plastic TO-92 variant;
intended for applications up to the
PINNING - TO-92 VARIANT
1 = drain
2 = source
3 = gate
VHF range.
These FETs can be supplied in four
I
groups. Special features are the
DSS
low feedback capacitance and the low
noise figure. Thanks to these special
handbook, halfpage
features the BF410 is very suitable for
applications such as the RF stages in
FM portables (type A), car radios
(type B) and mains radios (type C) or
the mixer stage (type D).
