The HA17358 is dual operational amplifiers which, provide internal phase compensation and high gain, and mono power source operation is possible. It can be widely applied to control equipment and to general use.
The S8050 is a low voltage high current small signal NPN transistor, designed for Class B push-pull audio amplifier and general purpose applications. S8050 0.5A/40V NPN Transistor TO-92.
The MJE350 is a silicon planar PNP transistor intended for use in medium power linear and switching applications. It is mounted in TO-126. The complementary NPN type is MJE340.
The Hall Effect Sensor Module can be used to detect the presence of an magnetic field. If there is an magnetic field present, it will report a high level signal.
