Transistor - JFET, N-Channel, MMBFJ201, SOT-23
Surface mount MMBFJ201 JFET. Commonly used in place of the discontinued through-hole J201. These JFETs can be found in many effects pedals, synthesizers, and other projects. The MMBFJ201 is an N-Channel general purpose amplifier JFET. This device is designed primarily for low level audio and general purpose applications with high impedance signal sources.
