Re: part enquiry

Gordon,
Regarding your part marked LF:
So far, it doesn't seem to cross to anything made by Philips, Siemens/Infineon, or ST. There's a good document on SMD markings that Infineon has. You may want to look at it, although your part did not show.
Other suspects are Zetex, International Rectifier ( if your part is actually a FET),  Panasonic and Toshiba.
If you tell us where this part is mounted on (toy, appliance, instrument, etc) and who made it, that may give us more clues.

Girish,
Regarding your part marked BM28682:
Need more details for further assistance.
