Electronic Components

2N4403 is a widely used PNP general purpose transistor. Due to its good technical features it is a hobbyist?s favorite transistor for their general purpose applications. Apart from that it can be used in wide variety of electronic applications like switching and amplification. The max collector current of the transistor is 600mA that is a quite good value in its size. With 600mA collector current it can be used to control variety of loads in electronic circuits.Moreover the transistor is also having Max collector dissipation of 625miliWatt and max DC current gain of 300 these are also some good value in this size package to use it as a small amplification or preamplification purposes.
