3309W-1-103 - Brand New BOURNS Trimmer Potentiometers
-
Description
The 3309W-1-103 is a trimmer potentiometer designed for regulating the output voltage in dioderectified alternator charging systems common to automotive applications. It provides either an analog or digital fixed frequency duty cycle control of an alternator's field current. The 3309W-1-103 features Load Response Control (LRC) to eliminate engine speed hunting and vibrations caused by sudden electrical loads at low engine RPM. It also has selectable LRC rates and controlled MOSFET and field flyback diode recovery characteristics for minimum RFI.
