Content for 2N4403


2N4403 is a general purpose PNP transistor used for low power switching and amplifier applications. The NPN complementary for the device is 2N4400, 2N4401. 2N4403 is basically used when you want a simple switching device for low power loads. The component is cheap and easy to work with so it is best suited when choosing a random switching device. 2N4403 can also used as a basic power amplifier and its application include amplifying low power signals.

Lightning Detector

“It is often in the pursuit of one project that leads one to build others. For example, let us say that the work of Victor Frankenstein was being prepared for duplication at the premier Louisville, KY hackerspace; LVL1. Instead of …

Rain Detector

“This rain detector will give you a heads-up the instant it starts to rain, hopefully giving you time to close windows and bring in possessions. The battery-powered circuit draws virtually no current when the sensor is dry and the current …
