Product specification

NPN 1 GHz wideband transistor

BFS17W

APPLICATIONS

Primarily intended as a mixer,

oscillator and IF amplifier in UHF and

VHF tuners.

DESCRIPTION

Silicon NPN transistor in a plastic

SOT323 (S-mini) package. The

BFS17W uses the same crystal as

the SOT23 version, BFS17.
