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 DS1669 Dallas™ is a single digital rheostat or potentiometer with access to all three potentiometer terminals. The potentiometer has 64 wiper positions with equal or linear resistive step sizes.
The MJE13003 is a 1.5A, 400V NPN Bipolar Power Transistor is designed for high voltage power switching inductive circuits where fall time is critical. They are particularly suited for 115 and 220V SWITCHMODE application.
