BF491K PNP Transistor

The BF491K is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the BF491K transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BF491K transistor symbol shows an arrow from the emitter into the base. This means that the current flows from emitter to collector terminal.

Circuit diagram symbol of the BF491K transistor as follows.
