Please Identify Electronic component

[bigbeark]

I realize this would be easier with a picture, but I can describe it very accurately.

It is found on a Yamaha Sound Card. It's a black plastic half-cylinder, vertically sliced in half, with three legs mounted to the soundcard via through holes and soldered in place, It's maybe 3/16 inch tall, maybe 1/8th inch in diameter.

Lettering on the flat side of the flat face says F942 or Fy42, followwd by "TM' on the next line, followed by u1133 on a third line, very hard to read.

I actually removed this bit off a Soundblaster card to replace the one on the Yamaha, which had broken off the Yamaha card. Didn't work, but probably the wrong value for this card.

So what is it and what does it do? Thanks all.

Isn't there a marking on the board at the base of the component? Something like TR, IC or Q followed by a number?

Well, the only one that might apply is "U3"

bigbeark,

Photo of the device with the marking would be helpful if you can. There are many camera that have good macro focus.

Agree with Wizard. U=IC. The package you are describing, if I understand it correctly, apply to several components.

Re: Please Identify Electronic component

Well I searched for a bit and didn't come up with anything. From what you described, the part seems to be something in a TO-92 package. These are commonly small transistors, small voltage regulators, and voltage references. It could be somebody's internal part number, in which case we'll never figure it out. A picture would be very helpful though.
