Transistor ID

[sasarchiver]

hi guys,
i have about 100 NPN and PNP transistors. but i dont know what ones are what. i see it has writing on them but i find it hard to ID them, is there a way to do this. thx in advance

Yes there is a way. You should give a little more information.

heres one
<a href="http://s134.photobucket.com/albums/q106/sasarchiver/electrics/?action=view&amp;current=SAM_0678.jpg" target="_blank"><img src="http://i134.photobucket.com/albums/q106/sasarchiver/electrics/SAM_0678.jpg" border="0" alt="Photobucket"></a>

on the reverse side it has the letter T

actually that ones abit obvious, BC337. ill go through the ones that are hard to work out...

Huh.

The BC 7-25 was a funny one. If search on alldatasheets, it is found (fooled me) but only because the phrase "7-25" is a chapter within a pdf file, and that is found when searcing.

However, google didn't returned anything relevant other than.

i have more like that too, ill need to get em out and take pics of em so i can get em sorted out. thx

these resistors?

26Ω 2%?

110Ω 1% ?

Man i have a lot of electric parts, i mean boxes, LEDs, Resistors,transistors,capacitors, it was ment to be a hobbie lol ended up spending alot of money instead lol

How did you ending up buying a lot of transistors without knowing their real ID ?

 

[sasarchiver]

i won a bid on ebay and the guy threw them in.

It would be easier for us if you just list the numbers instead of taking photos.

okie mate, np. just thought it would be easier with a pic.

just wanna state that im a total newbie.
