5 PCS SF137-D Transistors - RF Gain, 12V 200mA 300mW - Similar To BFY39

Alright electronics tinkerers, here's a grab for your parts bin.

This is a set of five SF137-D transistors.

They're designed for RF gain applications and run at 12V, 200mA, 300mW.

They're similar to the older BFY39 style, so if you're working on a vintage radio restoration or some kind of RF project, these might be exactly what you need.

They're new old stock, brand new and unused.

Five pieces give you some spares for experimenting or matching.

No brand name on these, just the part number and the specs you need to make your circuit work.
