BFY90 VHF/UHF NPN Silicon Transistor (Unused OLD stock)

BFY90

NPN Silicon

TO-72 case

Viewed clockwise underneath

Pin 1 (left of tab) Emitter

Pin 2 Base

Pin 3 Collector

Pin 4 Case shield

Ft 1.4Ghz typical

NF 2.5dB @ 200Mhz 5.5dB @ 800Mhz

Very high fT, low reverse capacitance, excellent cross modulation properties and very low noise performance.

Note the 4 legs, the extra being a case connection

COSMETIC CONDITION:

These are all unused but old stock from the radio workshops

I noticed a bit of oxidisation on the legs and would best describe them as a "dull shine" - easy to clean prior to soldering anyway
