As Altima said, it's a 22ohm SMD resistor. You'll need to measure it to get the package size.
Unfortunately resistors don't really just burn out. If the resistor did cause damage from overheating, it's because something drew too much current. My guess is there's a short somewhere else, but there's almost certainly more damage than that resistor.
Good luck!
I was thinking the same. How the heck does a resistor cause that much damage? Definitely not the resistors fault alone.
This right here. It’s likely not the resistor itself even though it’s showing the most symptoms of the overall problem.
Somewhere along that circuit branch is a short or something causing too much current to be drawn through the resistor here.
I dont think the resistors are faulty but the design. Resistors (especially low-ish value 22Ohm ones) are meant to dissipate energy as heat. Putting them in a cramped housing made of plastic, then using them to dissipate high power is going to build up heat in there. There could also be another component faulty that puts too much current into the resistors. They are probably part of the balancing circuit.
This is my first post here. Have I attached the photo correctly?
I can see the photo. Can't offer help though.
They are 22ohm resistors. You can see they are resistor by the marking R on the pcb. The first two digit is the value (22), the last is the multiplier (0), so it would be 22*10^0 =22 ohm
Looks like a 22 ohm resistor
Maybe I'm looking at the wrong thing, but I don't see melted plastic. I see a collapsed bubble (a "fisheye") in the conformal coating that is providing moisture resistance to the components.
