2N3707

Silicon NPN High-Gain Ultra-Low-Noise Audio Transistor, engineered specifically for low-level analog input amplification, magnetic tape head pre-amplifiers, and high-accuracy laboratory instrumentation feedback loops. It features an exceptionally high small-signal current gain parameter paired with a minimal noise figure metric, housed in a standard through-hole TO-92 plastic encapsulated package. Manufactured by Texas Instruments / Fairchild.
