Witch transistor should i choose for low noise audio ? Answered
Hello , im making a guitar pedal .The original schematic use transistor BC107B (epitaxial NPN) but i dont have it.so i find some other NPN transistor to replace it. I have 2N3903 ,2SC1815,2N3904 , but witch should i choose for low noise application ?
in their datasheet i found the "NF : noise figure" , the lower NF mean lower noise ??
BC107B NF Typ.= 2 Max.= 10
2N3903 NF Typ.= - Max.= 6
2N3904 NF Typ.= - Max.= 5
2SC1815 NF Typ.= 1 Max.= 10
Thanks for advance!
sorry for my bad English.
