Still playing with the lightning-hit modem from the other day. Have
tracked traces to a component I can't ID, and am unable to get any kind
of useful meter reading from.
Physical:
Approx 6.5mm long, slightly less - perhaps 4.5-5mm wide, < 2.5mm thick.
Solid black body with silver/grey-ish markings. Two protruding tabs, one
on each short side, bent down to make contact with solder pads on PCB.
Drawing/markings:
| Approx |
| 6.5mm |
| |
| |
V V
-------- <------
| St | Approx
|| BHH || 4-5mm
| C638 |
-------- <------
Other (possibly) helpful commentary:
The "St" is obviously a logo (and maddeningly enough, one that I
recognize, but can't put a company name with) with the top of the "S"
joined with/forming the crossbar of the "t", all done in "inverse
video", if you follow my meaning. A notation silk-screened on the board
near it (may or may not be related to the part, but because of its
position, I think it probably is) reads "TVS1".
Anybody know what this "little black box" is? I can get no reading out
of it with my meter set for ohms, in any range, in either direction -
Meter behaves as if it isn't connected to anything. Whether this is
normal for this part (TVS1 = "Transient Voltage Suppressor #1", perhaps?
Sorta like a MOV?), or a symptom of it being fried is a complete unknown.
Google gives me nothing that makes any kind of sense on "C638" or "BHH",
and I expected (and got) too many hits to even TRY wading through on
"St", most dealing with - you guessed it - catholic saints, but none (of
the 6 pages or so worth of results that I bothered flipping through)
related to electronics.
Anyone?
And in the spirit of "teaching me to fish" instead of just giving me
one, if you know what this critter is, it would be appreciated if you'd
enlighten me as to how and/or where you found the information.
Thanks!
