Default Never mind "Aw, shoot...", it's now "OH CRAP!"

New problem: I broke the J106L "shunt bypass cap" (SMT A-size 10uf 6.3V tantalum capacitor). Could I go to RadioShack tomorrow to get just any ol' 10uf capacitor, or does it really need to be a 6.3V tantalum? Is it OK if it's more or less than 10uf, if it's still 6.3V? Does it have to be *tanalum*?

Not a Zener, will consume 0,7v.

Zener diodes are the ones who prevent high current peaks from going through, they are like "reverse diodes".

Maybe I misread the datasheet, though, I'm studying probability and statistics and my head is kinda messed up right now.

EDIT: Disregard what I said, I just realized how wrong I was, sorry. I told you my head was messed up by this exam My guess is that you'll be fine, but we need some more information on the diode you desoldered, I do not know the rkcstr drive's layout.

I thought, though, the purpose of the diode in the driver was to provide reverse-current protection, in which case almost any diode should work.

Could be, but it depends on how it is placed, that's what led me to believe it was a zener. Maybe you should PM rkcstr and ask him what diode he used so you can replace it.

Uhm, as in the SMD marking, the 106J marking is a 10 uF tantalium capacitor, not a zener ..... and all the ones i have here, are capacitors, too

But if you don't have space problems, you can use any 10 uF 16V tantalium caps (the ones shaped as a tear, takes less space of the axial ones) ..... anyway, tantalium ones are better as quality, in those applications.

Just be sure to not revert the polarity ..... tantalium capacitors have the bad abitude to immediately die, and sometimes short circuit and take fire, if reverted.

Haha, the zener thing was before, he edited the OP with a new problem.

No need to apologize. I'm the same, especially when on Wikipedia.
