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).
