Zebralights are pita for modders and now and then some €&@“ happens.
I’m no exemption so to get to the point, i have opened Zebra SC5w, AA boost light and while removing driver i was lucky to damage one of the legs on the backside.
Now, since i’m ok soldering and modding but real dumb€&@ when it comes to knowing stuff, i would need your help to name the component i messed up.
I removed it completly from the board for this purpose.
Letters say 1.2UH and bellow is 1739A and size is 3x3x1.8mm so i guess 1210
As a side note, the boost converter is likely a LTC3425 (guessing from your photo); an expensive part, which is likely why the SC5 costs the same as the 18650 battery variants from ZL.
Nb: When ordering an inductor, you not only have to get the right inductance, but also make sure it can handle at least the rated current of the original.
It’s not a matter of “burning out” if the wire’s too thin. Well, it can be, but the main limitation is how much “magnetism” can go through the core. Too dense, and the core saturates. Just like an LED turning blue from too much current (ie, more current without any more light and often less light), the same happens to the inductor.
