Good all-purpose NPN signal transistor, but you should test the hFE (gain)

I needed matched pairs for a circuit and tested for hFE (gain) before using. Gain ranged from 207 to 260, with most hFE being in the 230's. Out of 20, I found 3 pair which matched and 2 others which would have been close enough.Inherent noise was low and the 2N2222A's were stable.

Pros

Versatile

Cons

While this lot may offer improved performance, it may not be worth purchasing if you don't require high-performance transistors. Cheaper or more basic alternatives may be suitable for your needs
