Hello all,
Maybe someone could help identify a component for me?
It's from a laptop's charger board. There are two on there, both on the 19V input line, one straight after the 19V comes to the board, so the rest of the board is fed through this part. The other has a similar function on the other end of the board, where the charging circuitry is. They are designated RS1 and RS2. The second pic shows more of the board to give an idea on size and perspective of the part.
They are in plastic packages - the first one on the board had got hot and was bulging and inflated considerably, like a balloon ready to pop. Still read short, though. The one which is pictured and working fine measures just 0.5 ohms on the meter, which is actually 0 ohms, since just connecting the meter probes together gives me 0.5 ohms resistance...
So, that rules them out as resistors, despite the odd marking of 50 m(ohm sign) F. If they're fuses, it didn't go open despite passing enough current to heat it up and melt it, and they're like none I've seen of the SMD variety, and I wouldn't know the rating from the odd markings on them.
Any ideas anyone please?
