QE RUM smd chip id anyone?
« on: 29 December 2017, 00:05:19 »
This chip is smokin' on a HDD control board for a 120GB Seagate Barracuda Model ST3120026A:
QE
RUM
are the only markings I can see. No markings on the PCB to tell either.  No polarity markings on pcb.
I plugged the atapi bridge -  usb p/s cable in reverse momentarily and may have damaged the component.  The strange part is it did not smoke when I had it plugged in backwards, only when I corrected it.
Thank you
