Hello all,

My first posting here. Can anybody help me identifying an SMD component that has no markings on it?

I uploaded two pictures of the same area of two identical boards. They are of a lithium battery pack.
In one a component burned out, and the same component can be seen on the good board. It's the area around the charging plug, I suspect some over voltage or polarity inversion made the damage.
Regardless the resson, is there any way to identify the burned out component by looking at the good picture? I tried to measure the resistance with a multimeter and I measured 0 ohm in both directions, so I don't think it's a diode. Perhaps a non polarized capacitor? Or a fuse, are there such things in SMD?

It is a surface mount inductor.
Cannot tell the inductance.
But you can use an inductance meter to test the good one after desoldering it

PS. It's not a good idea to use ur email as a username

It's safer to say it WAS a surface mount inductor.
