Hi
I visited my local Dick Smiths store today to buy a few transistors, when I noticed that they were getting rid of PN4258 transistors for 1 cent each. I didn't know what their specs were, but I figured that at 1 cent I couldn't go wrong - so I bought the whole stock, all 70 of them.
About half of the transistors have three color bars marked on their rounded surfaces of the TO92 package - red, silver, blue or white, brown , blue, or etc, etc.
I have never seen this before on any transistor, and the Fairchild data sheet does not mention it. What does it mean, please?
Thanks,
Andre
