HB9TRU Transistor Audion
USKA-FOS/HB9TRU-Transistor-Audion
Transistor-based Audion radio for shortwave reception

The BC848C is a bipolar made by ALJ in a SOT-23 package with 3 pins. -55℃~+150℃ 1 NPN 100MHz 100mA 100nA 200mW 30V 500mV 6V 800 NPN SOT-23 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:BC848, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 31,841 are in stock at JLCPCB (part C22400347). 4 open-source boards in 4 repositories on GitHub use it.
